Karbon Platform Services Overview

Karbon Platform Services is a Kubernetes-based multicloud platform as a service that enables rapid development and deployment of microservice-based applications. These applications can range from simple stateful containerized applications to complex web-scale applications across any cloud.

In its simplest form, Karbon Platform Services consists of a Service Domain encapsulating a project, application, and services infrastructure, and other supporting resources. It also incorporates project and administrator user access and cloud and data pipelines to help converge edge and cloud data.

With Karbon Platform Services, you can:

Quickly build and deploy intelligent applications across a public or private cloud infrastructure.
Connect various mobile, highly distributed data sensors (like video cameras, temperature or pressure sensors, streaming devices, and so on) to help collect data.
Create intelligent applications using data connectors and machine learning modules (for example, implementing object recognition) to transform the data. An application can be as simple as text processing code or it could be advanced code implementing AI by using popular machine learning frameworks like TensorFlow.
Push this data to your Service Domain or the public cloud to be stored or otherwise made available.

This data can be stored at the Service Domain or published to the cloud. You can then create intelligent applications using data connectors and machine learning modules to consume the collected data. These applications can run on the Service Domain or the cloud where you have pushed collected data.

Nutanix provides the Service Domain initially as a VM appliance hosted in an AOS AHV or ESXi cluster. You manage infrastructure, resources, and Karbon Platform Services capabilities in a console accessible through a web browser.

Cloud Management Console and User Experience

As part of initial and ongoing configuration, you can define two user types: an infrastructure administrator and a project user . The cloud management console and user experience help create a more intuitive experience for infrastructure administrators and project users.

Admin Console drop-down menu for infra admins and Home Console drop-down menu for project users. Both menus provide a list of all current projects and 1-click access to an individual project. In the navigation sidebar, Projects also provides a navigation path to the overall list of projects.
Vertical tabs for most pages and dashboards. For example, clicking Administration > Logging shows the Logging dashboard with related task and Alert tabs. The left navigation menu remains persistent to help eliminate excessive browser refreshes and help overall navigation.
Simplified Service Domain Management . In addition to the standard Service Domain list showing all Service Domains, a consolidated dashboard for each Service Domain is available from Infrastructure > Service Domain . Karbon Platform Services also simplifies upgrade operations available from Administration > Upgrades . For convenience, infra admins can choose when to download available versions to all or selected Service Domains, when to upgrade them, and check status for all or individual Service Domains.
Updated Workflows for Infrastructure Admins and Project Users . Apart from administration operations such as Service Domain, user management, and resource management, the infra admin and project user work flow is project-centric. A project encapsulates everything required to successfully implement and monitor the platform.
Updated GPU/vGPU Configuration Support . If your Service Domain includes access to a GPU/vGPU, you can choose its use case. When you create or update a Service Domain, you can specify exclusive access by any Kubernetes app or data pipeline or by the AI Inferencing API (for example, if you are using ML Models).

Built-In App Services, Logging, and Alerting

Karbon Platform Services includes these ready-to-use built-in services, which provide an advantage over self-managed services:

Secure by design.
No life cycle management. Service Domains do not require any user intervention to maintain or update service versions, patches, or other hands-on activities. For ease of use, all projects using the Service Domain use the same service version.
Dedicated service resources. Your project uses isolated service resources. Service resources are not shared with other projects. Applications within a project are not required to authenticate to use the service.
Service-specific alerts. Like other Karbon Platform Services features, the Service Domain helps monitor service health and raises service-specific alerts.

App Runtime Service

These services are enabled by default on each Service Domain. All services now have monitoring and status capabilities

Kubernetes Apps. Container-as-a-Service to manage and run Kubernetes apps without worrying about Kubernetes complexity and having to manage the underlying infrastructure.
Functions and Data Pipelines. Function-as-a-Service to run serverless functions. Invoke functions based on data triggers and publish to service end points.
AI Inferencing - updated in this release. ML model management and AI Inferencing runtime, pooled though an abstraction of GPUs and hardware accelerators. Enable this service to use your machine learning (ML) models in your project.

Ingress Controller

Ingress controller configuration and management is now available from the cloud management console (as well as from the Karbon Platform Services kps command line). Options to enable and disable the Ingress controller are available in the user interface.

Traefik or Nginx-Ingress. Content-based routing, load balancing, SSL/TLS termination. If your project requires Ingress controller routing, you can choose the open source Traefik router or the NGINX Ingress controller to enable on your Service Domain. You can only enable one Ingress controller per Service Domain.

Service Mesh

Istio. Provides traffic management, secure connection, and telemetry collection for your applications.

Data Streaming | Messaging

Kafka. Options to enable and disable Kafka are available in the user interface. Persistent, high performance data streaming with publish/subscribe and queue based messaging. Available for use within project applications and data pipelines, running on a Service Domain hosted in your environment.
NATS. In-memory, high performance data streaming with publish/subscribe and queue based messaging. Available for use within project applications and data pipelines. In-memory high performance data streaming including pub/sub (publish/subscribe) and queue-based messaging.

Logging | Monitoring | Alerting | Audit Trail

Prometheus. Provides Kubernetes app monitoring and logging, alerting, metrics collection, and a time series data model (suitable for graphing).
Logging. Centralized real-time log monitoring, log bundle collection, and external log forwarding.
Log forwarding policies for all users. Create, edit, and delete log forwarding policies to help make collection more granular, and then forward those Service Domain logs to the cloud - for example, AWS CloudWatch.
Audit trail. Karbon Platform Services maintains an audit trail of any operations performed by users in the last 30 days and displays them in an Audit Log dashboard in the cloud management console.

Infrastructure Administrator Role

Karbon Platform Services allows and defines two user types: an infrastructure administrator and a project user. An infrastructure administrator can create both user types.

Infrastructure administrator creates and administers most aspects of Karbon Platform Services. The infrastructure administrator provisions physical resources, Service Domains, services, data sources, and public cloud profiles. This administrator allocates these resources by creating projects and assigning project users to them. This user has create/read/update/delete (CRUD) permissions for:

Categories
Cloud profiles
Container registry profiles
Data sources
Service Domains
Projects
Users
Logs

When an infrastructure administrator adds another infrastructure administrator as a user to a project, that administrator is assigned the project user role for that project.

Infrastructure Administrator Role Capabilities

Project User Role

A project user can view and use projects created by the infrastructure administrator. This user can view everything that an infrastructure administrator assigns to a project. Project users can utilize physical resources, as well as deploy and monitor data pipelines and Kubernetes applications.

Karbon Platform Services allows and defines two user types: an infrastructure administrator and a project user. An infrastructure administrator can create both user types.

The project user has project-specific create/read/update/delete (CRUD) permissions: the project user can create, read, update, and delete the following and associate it with an existing project:

Kubernetes Apps
Functions (scripts)
Data pipelines
Runtime environments

When an infrastructure administrator adds another infrastructure administrator as a user to a project, that administrator is assigned the project user role for that project.

Naming Guidelines

Data Pipelines and Functions

When you create, clone, or edit a function, you can define one or more parameters. When you create a data pipeline, you define values for the parameters when you specify the function in the pipeline.
Data pipelines can share functions, but you can specify unique parameter values for the function in each data pipeline.

Service Domain, Data Source, and Data Pipeline Naming

Starts and ends with a lowercase alphanumeric character
Dash (-) and dot (.) characters are allowed.For example, my.service-domain is a valid Service Domain name.
Maximum length of 63 characters

Data Source Topic and Field Naming

Topic and field naming must be unique across the same data source types. You are allowed to duplicate names across different data source types. For example, an MQTT topic name and RTSP protocol stream name can share /temperature/frontroom.

An MQTT topic name must be unique when creating an MQTT data source. You cannot duplicate or reuse an MQTT topic name for multiple MQTT data sources.
An RTSP protocol stream name must be unique when creating an RTSP data source. You cannot duplicate or reuse an RTSP protocol stream name for multiple RTSP data sources.
A GigE Vision data source name must be unique when creating a GigE Vision data source. You cannot duplicate or reuse a GigE Vision data source name for multiple GigE Vision data sources.

Container Registry Profile Naming

Starts and ends with a lowercase alphanumeric character
Dash (-) and dot (.) characters are allowed.
Maximum length of 200 characters

All Other Resource Naming

Starts and ends with a lowercase alphanumeric character
Dash (-) and dot (.) characters are allowed. For example, my.service-domain is a valid Service Domain name
Maximum length of 200 characters

Certificates Used with MQTT Data Sources

Each Service Domain image is preconfigured with security certificates and public/private keys.

When you create an MQTT data source, you generate and download a ZIP file that contains X.509 sensor certificate (public key) and its private key and Root CA certificates. Install these components on the MQTT enabled sensor device to securely authenticate the connection between an MQTT enabled sensor device and Service Domain. See your vendor document for your MQTT enabled sensor device for certificate installation details.

Certificates downloaded from the Karbon Platform Services management console have an expiration date 30 years from the certificate creation date. Download the certificate ZIP file each time you create an MQTT data source. Nutanix recommends that you use each unique set of these security certificates and keys for any MQTT data sources you add.

Onboard and Manage Your Service Domain

The Karbon Platform Services cloud management console provides a rich administrative control plane to manage your Service Domain and its infrastructure. The topics in this section describe how to create, add, and upgrade a Service Domain.

Checking Service Domain Details

In the cloud management console, go to Infrastructure > Service Domains to add a VM-based Service Domain. You can also view health status, CPU/Memory/Storage usage, version details, and more information for every service domain.

Upgrading a Service Domain

In the cloud management console, go to Administration > Upgrades to upgrade your existing Service Domains. This page provides you with various levels of control and granularity over your maintenance process. At your convenience, download new versions for all or specific Service Domains and upgrade them with "1-click".

Onboarding a Multinode Service Domain By Using Nutanix Karbon

You can now onboard a multinode Service Domain by using Nutanix Karbon as your infrastructure provider to create a Service Domain Kubernetes cluster. To do this, use Karbon on Prism Central with the kps command line and cloud management console Create a Service Domain workflow. See Onboarding a Multinode Service Domain By Using Nutanix Karbon. (You can also continue to use other methods to onboard and create a Service Domain, as described in Onboarding and Managing Your Service Domain.)

For advanced Service Domain settings, the Nutanix public Github repository includes a README file describing how to use the command line and the required YAML configuration file for cluster.

This public Github repository at https://github.com/nutanix/karbon-platform-services/tree/master/cli also describes how to install the command line and includes sample YAML files for use with applications, data pipelines, data sources, and functions.

About the Service Domain Image Files

The Karbon Platform Services Release Notes include information about any new and updated features for the Service Domain. You can create one or more Service Domains depending on your requirements and manage them from the Karbon Platform Services management console.

The Service Domain is available as a qcow disk image provided by Nutanix for hosting the VM in an AOS cluster running AHV.

The Service Domain is also available as an OVA disk image provided by Nutanix for hosting the VM in a non-Nutanix VMware vSphere ESXi cluster. To deploy a VM from an OVA file on vSphere, see the documentation at the VMware web site describing how to deploy a virtual machine from an OVA file for your ESXi version

Each Service Domain you create by using these images are configured with X.509 security certificates.

If your network requires that traffic flow through an HTTP/HTTPS proxy, see HTTP/HTTPS Proxy Support for a Service Domain VM.

Download the Service Domain VM image file from the Nutanix Support portal Downloads page. This table describes the available image file types.

Table 1. Service Domain Image Types
Service Domain Image Type	Use
QCOW2	Image file for hosting the Service Domain VM on an AHV cluster
OVA	Image file for hosting the Service Domain VM on vSphere.

Deploying the Service Domain Image on a Bare Metal Server

Before you begin

For installing the Service Domain on bare metal, see About the Service Domain Image Files for available image types. In this procedure, you can use a RAW or EFI RAW compressed Service Domain image depending on the bare metal server BIOS type.
For a list of approved hardware for bare metal installation, contact Nutanix Support or send email to kps@nutanix.com.
Before imaging the bare metal server, prepare it by updating any required firmware and performing hardware RAID virtual disk configuration.
Minimum destination disk size is 200 GB.
Single node Service Domain support only. Multinode Service Domains are not supported.

Procedure

Download and boot a live image.
You can image the bare metal serve by live-booting any Linux operating system that includes destination driver support and these utilities or packages: lshw (list hardware), tar (tape archive), gzip (GNU compression utilitiy), dd (file convert and copy). You can live-boot an image through a USB or BMC connection. These steps use an Ubuntu distro and USB drive as an example.
1. Use MacOS or Microsoft Windows, create an Ubuntu bootable USB drive.
2. Download the Service Domain image and copy to the USB drive.
3. Boot from the Ubuntu bootable USB drive with the Try Ubuntu option.
In Ubuntu, open Terminal, find the destination disk, and image it.
1. Find the destination disk.
```
$ sudo lshw -c disk
```
2. Go to the directory where you saved the Service Domain image. For example, where drive_label is the USB drive:
```
$ cd /media/ubuntu/drive_label
```
3. Image the destination disk. For example:
```
$ sudo tar -xOzvf service-domain-image.raw.tgz | sudo dd of=destination_disk bs=1M status=progress
```
  - service-domain-image.raw .tgz. RAW or EFI RAW compressed Service Domain image you downloaded and copied to the USB drive.
  - destination_disk . Destination disk. For example, /dev/sda , /dev/nvme0n1 , and so on.
When imaging is completed successfully, restart the baremetal server.
1. Connect the primary network interface to a network with DHCP.
2. Remove the USB drive.
3. Restart the bare metal server and note the IP address received from DHCP on boot.
During startup (boot), note the IP address assigned by the DHCP server.

Deploying the Service Domain on Amazon Web Services

Before you begin

For installing the Service Domain on Amazon Web Services (AWS), see About the Service Domain Image Files for available image types. In this procedure, you can use a RAW uncompressed Service Domain image.
You need an AWS account to deploy the Service Domain on AWS.
Nutanix recommends that you create a new dedicated Amazon S3 bucket for the Service Domain. This procedure applies a new trust policy to the S3 bucket storing the Service Domain. Creating a dedicated S3 bucket helps avoid other policies or configurations being inadvertently being applied to the Service Domain.
Install configure the AWS command line interface aws on your local machine, so that you can communicate with AWS as required in these steps. For convenience, download the Service Domain image to this machine.
Single node Service Domain support only. Multinode Service Domains are not supported.

Procedure

Create an AWS S3 bucket and copy the Service Domain RAW image to it.
1. Create the bucket.
```
$ aws s3 mb s3://raw-image-bkt
```
  - raw-image-bkt . Name of the your S3 bucket.
  - aws_region . Your AWS Region.
2. Copy the Service Domain RAW image to the bucket you just created.
```
$ aws s3 cp service-domain-image.raw s3://raw-image-bkt
```
  - service-domain-image.raw . RAW uncompressed Service Domain image you downloaded.

In a text editor, create a new trust policy configuration file named trust-policy.json .

{
   "Version": "2012-10-17",
   "Statement": [
      {
         "Effect": "Allow",
         "Principal": { "Service": "vmie.amazonaws.com" },
         "Action": "sts:AssumeRole",
         "Condition": {
            "StringEquals":{
               "sts:Externalid": "vmimport"
            }
         }
      }
   ]
}

Create a role named vmimport and grant VM Import/Export access to it.

$ aws iam create-role --role-name vmimport --assume-role-policy-document file://trust-policy.json

Create a new role policy configuration file named role-policy.json .

Make sure you replace raw-image-bkt with the actual name of your S3 bucket.

{
   "Version":"2012-10-17",
   "Statement":[
      {
         "Effect": "Allow",
         "Action": [

            "s3:PutObject",
            "s3:GetBucketAcl"
         ],
         "Resource": [
            "arn:aws:s3:::raw-image-bkt",
            "arn:aws:s3:::raw-image-bkt/*"
         ]
      },
      {
         "Effect": "Allow",
         "Action": [
            "ec2:ModifySnapshotAttribute",
            "ec2:CopySnapshot",
            "ec2:RegisterImage",
            "ec2:Describe*"
         ],
         "Resource": "*"
      }
   ]
}

Attach the role policy in role-policy.json to the vmimport role.

$ aws iam put-role-policy --role-name vmimport --policy-name vmimport --policy-document file://role-policy.json

Create a file named container.json .
Make sure you replace raw-image-bkt with the actual name of your S3 bucket and service-domain-image.raw with the name of the RAW uncompressed Service Domain image.
```
{
     "Description": "Karbon Platform Services Raw Image",
     "Format": "RAW",
     "UserBucket": {
        "S3Bucket": "raw-image-bkt",
        "S3Key": "service-domain-image.raw"
    }
 }
```
Import the snapshot as an Amazon Machine Image (AMI) by specifying container.json .
```
$ aws ec2 import-snapshot --description "exampletext" --disk-container "file://container.json"
```
The command output displays a task_id . With the task_id , you can see the snapshot task progress as follows:
```
$ aws ec2 describe-import-snapshot-tasks --import-task-ids task_id
```

After the task completes successfully, get the snapshot ID ( SnapshotId , needed for the next steps).

$ aws ec2 describe-import-snapshot-tasks --import-task-ids task_id

Example completed task status output:

{
    "ImportSnapshotTasks": [
        {
            "Description": "Karbon Platform Services Raw Image",
            "ImportTaskId": "import-task_id",

                   "S3Key": "service-domain-image.raw"
                }
            }
        }
    ]
}

Registering and Launching the Image in the EC2 Console

Procedure

To register the AMI from the snapshot, run this command.

$ aws ec2 register-image --virtualization-type hvm \
--name "Karbon Platform Services Service Domain Image" --architecture x86_64 \
--root-device-name "/dev/sda1"  --block-device-mappings \
"[{\"DeviceName\": \"/dev/sda1\", \"Ebs\": {\"SnapshotId\": \"snapshot_ID\"}}]"

snapshot_ID . Snapshot ID from completed task status output

In the EC2 console, go to Images > AMIs , and select the AMI you created.
Click Launch .
1. For Choose Instance Type , select an instance with minimum 4 vCPUs and 16GiB memory.
2. Click through to Add Storage and create an EBS volume with minimum disk size of 100 GiB and a device name of /dev/xvdf .
3. Proceed to Review .
4. In the Select an existing key pair or create a new key pair dialog box, use an existing key pair or create a new pair.
5. If you create a new key pair, download the corresponding .PEM file.
Launch the AMI.

Return to the AWS CLI and get the Public and Private IP address of your instance by using the instance ID instance_id .

$ aws ec2 describe-instances --instance-id instance_id --query 'Reservations[].Instances[].[PublicIpAddress]' --output text | sed '$!N;s/\n/ /'

HTTP/HTTPS Proxy Support for a Service Domain VM

Attach a cloud-init script to configure HTTP/HTTPS proxy server support.

If your network policies require that all HTTP network traffic flow through a proxy server, you can configure a Service Domain to use an HTTP proxy. When you create the service domain VM, attach a cloud-init script with the proxy server details. When you then power on the VM and it fully starts, it will include your proxy configuration.

If you require a secure proxy (HTTPS), use the cloud-init script to upload SSL certificates to the Service Domain VM.

You can attach or copy the script in the Custom Script section of the Nutanix AOS cluster Create VM dialog box.

This picture shows the cloud-init section of the Nutanix AOS cluster Create VM dialog box.

Sample cloud-init Script for HTTPS Proxy Server Configuration

This script creates an HTTP/HTTPS proxy server configuration on the Service Domain VM after you create and start the VM. Note that CACERT_PATH= in the first content spec is optional in this case, as it is already specified in the second path spec.

#cloud-config
#vim: syntax=yaml

Manage a Multinode Service Domain

Create and deploy a Service Domain cluster that consists of three or more nodes.

Caution: Nutanix does not support upgrading Tech Preview multinode Service Domains to generally available Service Domain versions, then deploying those Service Domains in a production environment. For example, upgrading a multinode Service Domain v1.18 to v2.0.0, then using that Service Domain in production.

A multinode Service Domain is a cluster initially consisting of a minimum of three leader nodes. Each node is a single Service Domain VM hosted in an AHV cluster.

Creating and deploying a multinode Service Domain is a three-step process:

Log on to the AHV cluster web console and upload the Service Domain disk image to a Nutanix AHV cluster through the image service as described in Uploading the Service Domain Image.
Create three or more Service Domain VMs from this disk image, as described in Creating and Starting the Service Domain VM.
Add a multinode Service Domain in the Karbon Platform Services management console as described in Adding a Multinode Service Domain.

Multinode Service Domain Requirements and Limitations

The Service Domain image version where Karbon Platform Services introduces this feature is described in the Karbon Platform Services Release Notes.

Service Domain VM hosting

Create and then start Service Domain VMs in a Nutanix AHV cluster only.

Single node Service Domain

You can create a single node Service Domain from a multinode compatible image version. It must remain a single node Service Domain, as you cannot expand this domain type.
You can upgrade an existing single node Service Domain to a multinode compatible image version, but it is limited for use as a single node Service Domain only.

Supported multinode Service Domain configuration

You can add a multinode Service Domain consisting of three Service Domain nodes initially created from a multinode compatible image version only.
Each node in a multinode Service Domain must reside on the same subnet.
You cannot mix image versions. Create each node in a multinode Service Domain from the same image version. You can also upgrade them to the same multinode compatible version later.

Service Domain High Availability Kubernetes API Support

Starting with new Service Domain version 2.3.0 deployments, high availability support for the Service Domain is now implemented through the Kubernetes API server (kube-apiserver). This support is specific to new multinode Service Domain 2.3.0 deployments. When you create a multinode Service Domain to be hosted in a Nutanix AHV cluster, you must specify a Virtual IP Address (VIP), which is typically the IP address of the first node you add.

To enable the HA kube-apiserver support, ensure that the VIP address is part of the same subnet for all Service Domain VMs and the VIP address has not already been allocated to any VM. Otherwise, the Service Domain will not enable this feature.
Also ensure that the VIP address in this case is not part of any cluster IP address pool range that you have specified when you created a virtual network for guest VMs in the AHV cluster. That is, the VIP address must be outside this IP pool address range. Otherwise, creation of the Service Domain in this case will fail.

Adding or removing nodes from a multinode Service Domain

You can add or remove nodes to an existing multinode Service Domain. However, you cannot remove the first three nodes you add to the Service Domain. These nodes are tagged as leader nodes. Each subsequent node you add is a worker node and is removable.

Configuring Storage and Storage Infrastructure

Each node requires access to shared storage from an AOS cluster. Ensure that you meet the following requirements to create a storage profile. Adding a Multinode Service Domain requires these details.

On your AOS cluster:

Create a Cluster Administrator user dedicated for use with this feature. Do not use this admin user for day-to-day AOS cluster tasks. For information about creating a user role, see Creating a User Account in the Security Guide .
You must configure the AOS cluster with a cluster virtual IP address and an iSCSI Data Services IP address. See Modifying Cluster Details in the Prism Web Console Guide .
Ensure that the AOS cluster has at least one storage container available for shared storage use by the nodes. If you want to optionally maintain a storage quota for use by the nodes, create a new storage container. See Creating a Storage Container in the Prism Web Console Guide .
Get the storage container name from the Prism Element web console Storage dashboard. Do not use the NutanixManagementShare or SelfServiceContainer storage containers. AOS reserves these storage containers for special use.

Unsupported multinode Service Domain configurations

Nutanix does not support the following configurations.

You cannot create (add) a multinode Service Domain where you have upgraded each node to a multinode compatible version from a previous incompatible single-node-only version.
For example, you have upgraded three older single-node Service Domains to a multinode image version. You cannot create a multinode Service Domain from these nodes.
In a multinode Service Domain, you cannot mix Service Domain nodes that you have upgraded to a multinode compatible version with newly created multinode compatible nodes.
For example, you have upgraded two older single-node Service Domains to a multinode image version. You have a newly created multinode compatible single node. You cannot add these together to form a new muiltinode service domain.
Service domain version 1.14 and previous versions allow you to create single node Service Domains only. These Service Domain nodes are not "multinode aware" but are still useful as single node Service Domains.

Adding a Multinode Service Domain

Create and deploy a Service Domain cluster that consists of three or more nodes.

Before you begin

See Multinode Service Domain Requirements and Limitations.
If you deploy each Service Domain node as a VM, the procedure described in Creating and Starting the Service Domain VM can provide the VM ID (serial number) and IP address.
After adding a Service Domain, the status and dot color shows Service Domain status and can take a few minutes to update. See also Example: Managing a Service Domain From Its Dashboard.
- Healthy (green). Service domain nodes started and connected.
- Not Onboarded (gray). Service domain nodes have not started and are not yet connected. Might be transitioning to Healthy.
- Disconnected (red). Service domain nodes have not started and are not connected. VM might be offline or unavailable.

Adding Each Node

Procedure

Log on to the cloud management console at https://karbon.nutanix.com/.
Click Infrastructure > Service Domains > + Service Domain .
Select Any other On-prem or Cloud Environment and click Next .
Name your Service Domain.
- Starts and ends with a lowercase alphanumeric character
- Maximum length of 63 lowercase alphanumeric characters
- Dash (-) and dot (.) characters are allowed. For example, my.service-domain is a valid Service Domain name.
Select Multi-Node to create a multinode Service Domain type.
Click Add Node and enter the following node details:
1. Name the node.
2. Serial Number of your Service Domain node VM.
  - If a Nutanix AOS cluster hosts your Service Domain node VM: in the cluster Prism web console, open the VM page, select the Service Domain node VM, and note the ID.
  - You can also display the serial number by opening this URL in a browser. Use your Service Domain node VM IP address: http://service-domain-node-ip-address:8080/v1/sn
3. IP Address of your Service Domain node VM.
  The IP address of the first node you add becomes the Service Domain Virtual IP Address . By default, Karbon Platform Services uses this node IP address to represent the Service Domain cluster in the Service Domains List page.
4. Subnet Mask and Gateway . Type the subnet mask and gateway IP address in these fields.
5. Click the check mark icon. To change the details, hover over the ellipses menu and click Edit .
6. Click Add Node and repeat these steps to add two leader nodes and worker nodes.
  The first three nodes are tagged as leader nodes and cannot be removed. Nodes four and later are considered as worker nodes and can be removed.
7. Virtual IP Address . The IP address of the first node you add becomes the Service Domain Virtual IP Address . By default, this node IP address represents the Service Domain cluster in the Service Domains List page.
  
  Starting with new Service Domain version 2.3.0 deployments, high availability support for the Service Domain is now implemented through the Kubernetes API server (kube-apiserver). This support is specific to new multinode Service Domain 2.3.0 deployments.
  
  To enable the HA kube-apiserver support, ensure that the VIP address is part of the same subnet as the Service Domain VMs and the VIP address is unique (that is, has not already been allocated to any VM). Otherwise, the Service Domain will not enable this feature.
  
  Also ensure that the VIP address in this case is not part of any cluster IP address pool range that you have specified when you created a virtual network for guest VMs in the AHV cluster. That is, the VIP address must be outside this IP pool address range. Otherwise, creation of the Service Domain in this case will fail.

Upgrade Service Domains

Your network bandwidth might affect how long it takes to completely download the latest Service Domain version. Nutanix recommends that you perform any upgrades during your scheduled maintenance window.

Note: Each Kubernetes release potentially deprecates or removes support for API versions or resources. To help ensure that your applications run correctly after upgrading your Service Domain version, Nutanix recommends that you check the Deprecated API Migration Guide available at the Kubernetes Documentation web site. Depending on the deprecated or removed APIs, you might have to modify your Kubernetes App YAML files.

Upgrade your existing Service Domain VM by using the Upgrades page in the cloud management console. From Upgrades , you can see available updates that you can download and install on one or more Service Domains of your choosing.

Upgrading the Service Domain is a two-step process where you:

Download an available upgrade to one or more existing Service Domains.
Upgrade selected Service Domains to the downloaded version.

Upgrades lets you choose how to upgrade your Service Domains.

Note: During a Service Domain upgrade operation, you might see service or app related alerts such as Kafka is degraded, partitions are under-replicated, and others. These messages are expected and can be safely ignored when you are upgrading your Service Domain. Nutanix recommends that you perform installation and upgrades during your scheduled maintenance window or outside your normal business hours.

Table 1. Upgrades Page Links
Link	Use Case
Service Domains	"1-click" download or upgrade for all upgrade-eligible Service Domains. Select the most recent available version (N) or the next most recent available versions (N-1, and N-2). For example, if your current Service Domain version is 1.16, you can download, then upgrade your Service Domain to available versions 1.16.1, 1.17, and 1.18. Upgrade all Service Domains where you have already downloaded the selected available Service Domain version(s)

Projects

A project is an infrastructure, apps, and data collection created by the infrastructure administrator for use by project users.

When an infrastructure administrator creates a project and then adds themselves as a user for that project, they are assigned the roles of project user and infrastructure administrator for that project. When an infrastructure administrator adds another infrastructure administrator as a user to a project, that administrator is assigned the project user role for that project.

A project can consist of:

Existing administrator or project users
A Service Domain
Cloud profile
Container registry profile

When you add a Service Domain to a project, all resources such as data sources associated with the Service Domain are available to the users added to the project.

Projects Page

The Projects page lets an infrastructure administrator create a new project and lists projects that administrators can update and view.

For project users, the Projects page lists projects created and assigned by the infrastructure administrator that project users can view and add apps and data. Project users can view and update any projects assigned by the administrator with applications, data pipelines, and so on. Project users cannot remove a project.

Managing Project Services

The Karbon Platform Services cloud infrastructure provides services that are enabled by default. It also provides access to services that you can enable for your project.

The platform includes these ready-to-use services, which provide an advantage over self-managed services:

Secure by design.
No life cycle management. Service Domains do not require any user intervention to maintain or update service versions, patches, or other hands-on activities. For ease of use, all projects using the Service Domain use the same service version.
Dedicated service resources. Your project uses isolated service resources. Service resources are not shared with other projects. Applications within a project are not required to authenticate to use the service.
Service-specific alerts. Like other Karbon Platform Services features, the Service Domain helps monitor service health and raises service-specific alerts.

App Runtime Services

These services are enabled by default on each Service Domain.

Kubernetes Apps. Containers as a service. You can create and run Kubernetes apps without having to manage the underlying infrastructure.
Functions and Data Pipelines. Run server-less functions based on data triggers, then publish data to specific cloud or Service Domain endpoints.
AI Inferencing. Enable this service to use your machine learning (ML) models in your project. The ML Model feature provides a common interface for functions (that is, scripts) or applications.

Ingress Controller

Traefik or Nginx-Ingress. If your project requires Ingress controller routing, you can choose the open source Traefik router or the NGINX Ingress controller to enable on your Service Domain. See Enable an Ingress Controller.

Service Mesh

Istio. Provides secure connection, traffic management, and telemetry. See Istio Service Mesh.

Data Streaming | Messaging

Kafka. Available for use within project applications and data pipelines, running on a Service Domain hosted in your environment. See Kafka as a Service.
NATS. Available for use within project applications and data pipelines. In-memory high performance data streaming including pub/sub (publish/subscribe) and queue-based messaging.

Logging | Monitoring | Alerting

Prometheus. Provides Kubernetes app monitoring and logging, alerting, metrics collection, and a time series data model (suitable for graphing). See Prometheus Application Monitoring and Metrics as a Service.

Enabling or Disabling One or More Services for a Project

Enable or disable services associated with your project.

Before you begin

You cannot disable the default Kubernetes Apps, Functions and Data Pipelines, and AI Inferencing services.
Disabling Kafka. When you disable Kafka, data stored in PersistentVolumeClaim (PVC) is not deleted and persists. If you later enable Kafka on the same Service Domain, the data is reused.
Disabling Prometheus. When you disable Prometheus and then later enable it, the service creates a new PVC and clears any previously-stored metrics data stored in PVC.

Procedure

From the home menu, click Projects , then click a project.
Depending on your role, you can also select a project from Admin Console drop-down menu.
Click Manage Services .
Enable a service.
1. Click Enable in a service tile.
2. Click Enable service_name .
  For Istio, apps in this project restart.
3. Click Confirm .
If the minimum Service Domain version is detected, the service is available for use in your project in a few minutes, after the service initializes. Otherwise, an alert is triggered if the Service Domain does not support the service.
Disable a service.
1. Click Disable in a service tile.
2. Click Disable service_name .
  For Istio, apps in this project restart.
3. Click Confirm .
The service is no longer available for use in your project.

Kafka as a Service

Kafka is available as a data service through your Service Domain.

The Kafka data service is available for use within a project's applications and data pipelines, running on a Service Domain hosted in your environment. The Kafka service offering from Karbon Platform Services provides the following advantages over a self-managed Kafka service:

Secure by design.
No need to explicitly declare Kafka topics. With Karbon Platform Services Kafka as a service, topics are automatically created.
No life cycle management. Service Domains do not require any user intervention to maintain or update service versions, patches, or other hands-on activities. For ease of use, all projects using the Service Domain use the same service version.
Dedicated service resources. Your project uses isolated service resources. Service resources are not shared with other projects. Applications within a project are not required to authenticate to use the service.
Service-specific alerts. Like other Karbon Platform Services features, the Service Domain monitors service health and raises service-specific alerts.

Using Kafka in an Application

Information about application requirements and sample YAML application file

Create an application for your project as described in Creating an Application and specify the application attributes and configuration in a YAML file.

Sample Kafka Application YAML Template File


apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-app-deployment
  labels:
    app: my-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      containers:
      - name: my-app
        image: some.container.registry.com/myapp:1.7.9
        ports:
        - containerPort: 80
     env:
        - name: KAFKA_ENDPOINT
          value: {{.Services.Kafka.Endpoint}}


Field Name	Value or Field Name / Description	Value or Field Name / Description
`kind`	`Deployment`	Specify the resource type. Here, use `Deployment` .
`metadata`	`name`	Provide a name for your deployment.
	`labels`	Provide at least one label. Here, specify the application name as `app: my-app`
`spec`		Define the Kafka service specification.
	`replicas`	Here, 1 to indicate a single Kafka cluster (single Service Domain instance or VM) to keep data synchronized.
	`selector`	Use `matchLabels` and specify the `app` name as in `labels` above.
	`template`
		Specify the application name here ( `my-app` ), same as `metadata` specifications above.
	`spec`	Here, define the specifications for the application using Kafka.
	`containers`	`name: my-app` . Specify the container application `image: some.container.registry.com/myapp:1.7.9` . Define the container registry host address where the container image is stored. `ports: containerPort: 80` . Define the container registry port. Here, 80.
	`env`	`name: KAFKA_ENDPOINT` `value: {{.Services.Kafka.Endpoint}}` Leave these values as shown.

Using Kafka in a Function for a Data Pipeline

Information about data pipeline function requirements.

See Functions and Data Pipelines.

You can specify a Kafka endpoint type in a data pipeline. A data pipeline consists of:

Input. An existing data source or real-time data stream (output from another data pipeline).
Transformation. A function (code block or script) to transform data from a data source (or no function at all to pass data directly to the endpoint).
Output. An endpoint destination for the transformed or raw data.

Kafka Endpoint Function Requirements

For a data pipelines with a Kafka topic endpoint:

Language . Select the golang scripting language for the function.
Runtime Environment . Select the golang runtime environment for the function. A default runtime environment is already selected in most cases depending on the Language you have selected.

Viewing Kafka Status

In the cloud management console, you can view Kafka data service status when you use Kafka in an application or as a Kafka endpoint in a data pipeline as part of a project. This task assumes you are logged in to the cloud management console.

Procedure

Click the menu button, then click Projects .
Click a project in the list.
The project dashboard is displayed along with Edit and Manage Services buttons.
Click Kafka .
This dashboard shows a consolidated, high-level view of all Kafka topics, deployments, and related alerts. The default view is Topics.
To show all topics for this project, click Topics .
1. Topics. All Kafka topics used in this project.
2. Service Domain. Service Domains in the project employing Kafka messaging.
3. Bytes/sec produced and Bytes/sec consumed. Bandwidth use.
To view Service Domain status where Kafka is used, click Deployments .
1. List of Service Domains and provisioned status.
2. Brokers. A No Brokers Available message might mean the Service Domain is not connected.
3. Alerts. Number of Critical (red) and Warning (yellow) alerts.
To see all alerts associated with Kafka for this project, click Alerts .

Enable an Ingress Controller

The Service Domain supports the Traefik open source router as the default Kubernetes Ingress controller. You can also choose the NGINX ingress controller instead.

An infrastructure admin can enable an Ingress controller for your project through Manage Services as described in Managing Project Services. You can only enable one Ingress controller per Service Domain.

When you include Ingress controller annotations as part of your application YAML file, Karbon Platform Services uses Traefik as the default on-demand controller.

If your deployment requires it, you can alternately use NGINX (ingress-nginx) as a Kubernetes Ingress controller instead of Traefik.

In your application YAML, specify two snippets:

Service snippet. Use annotations to define the HTTP or HTTPS host protocol, path, service domain, and secret for each Service Domain to use as an ingress controller. You can specify one more Service Domains.
Secret snippet. Use this snippet to specify the certificates used to secure app traffic.

Sample Ingress Controller Service Domain Configuration

To securely route application traffic with a Service Domain ingress controller, create YAML snippets to define and specify the ingress controller for each Service Domain.

You can only enable and use one Ingress controller per Service Domain.

Create an application for your project as described in Creating an Application to specify the application attributes and configuration in a YAML file. You can include these Service and Secret snippets Service Domain ingress controller annotations and certificate information in this app deployment YAML file.

Istio Service Mesh

Istio provides secure connection, traffic management, and telemetry.

Add the Istio Virtual Service and DestinationRules to an Application - Example

In the application YAML snippet or file, define the VirtualService and DestinationRules objects.

These objects specify traffic routing rules for the recommendation-service app host. If the traffic rules match, traffic flows to the named destination (or subset/version of it) as defined here.

In this example, traffic is routed to the recommendation-service app host if it is sent from the FireFox browser. The specific policy version ( subset ) for each host helps you identify and manage routed data.

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: recomm-svc
spec:
  hosts:
  - recommendation-service
  http:
  - match:
    - headers:
        user-agent:
          regex: .*Firefox.*
    route:
    - destination:
        host: recommendation-service
        subset: v2
  - route:
    - destination:
        host: recommendation-service
        subset: v1

This DestinationRule YAML snippet defines a load-balancing traffic policy for the policy versions ( subsets ), where any healthy host can service the request.

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: recomm-svc
spec:
  host: recommendation-service
  trafficPolicy:
    loadBalancer:
      simple: RANDOM
  subsets:
  - name: v1
    labels:
      version: v1
  - name: v2
    labels:
      version: v2

Manage Traffic by Weight - Example

In this YAML snipped, you can split traffic for each subset by specifying a weight of 30 in one case, and 70 in the other. You can also weight them evenly by giving each a weight value of 50.

apiVersion: networking.istio.io/v1beta1
kind: VirtualService
metadata:
  name: recomm-svc
spec:
  hosts:
  - recommendation-service
  http:
  - route:
    - destination:
       host: recommendation-service
       subset: v2
      weight: 30   
    - destination:
       host: recommendation-service
       subset: v1
      weight: 70

Viewing Istio Details

In the cloud management console, you can view Istio service mesh status associated with applications in a project. This task assumes you are logged in to the cloud management console.

About this task

The Istio tabs show service resource and routing configuration information derived from project-related Kubernetes Apps YAML files and service status.

Procedure

Click the menu button, then click Projects .
Click a project in the list, then click Istio in the navigation sidebar to show the default Application Metrics page.
Application Metrics shows initial details about the applications and related traffic metrics.
1. Name and Service Domain. Application name and Service Domain where the application is deployed and the Istio service is enabled.
2. Workloads. One or more workloads associated with the application. For example, Kubernetes Deployments, StatefulSets, DaemonSets, and so on.
3. Inbound Request Volume / Outbound Request Volume. Inbound/Outbound HTTP requests per second for the last 5 minutes
To see details about any traffic routing configurations associated with the application, click Virtual Services .
An application can specify one or more virtual services, which you can deploy across one or more Service Domains.
1. Application and Virtual Services. Application and service name.
2. Service Domains. Number and name of the Service Domains where the service is deployed.
3. Matches. Lists matching traffic routes.
4. Destinations. Number of service destination host connection or request routes. Expand the number to show any destinations served by the virtual service (v1, v2, and so on) where traffic is routed. If specified in the Virtual Service YAML file, Weight indicates the proportion of traffic routed to each host. For example, Weight: 50 indicates that 50 percent of the traffic is routed to that host.
To see rules associated with Destinations, click Destination Rules .
An application can specify one or more destination rules, which you can deploy across one or more Service Domains. A destination rule is a policy that is applied after traffic is routed (for example, a load balancing configuration).
1. Application. Application where the rule applies.
2. Destination Rules. Rules by name.
3. Service Domains. Number and name of the Service Domains where the rule is deployed.
4. Subsets. Name and number of the specific policies (subsets). Expand the number to show any pod labels (v1, v2, and so on), service versions (v1, v2, and so on), and traffic weighting, where rules apply and traffic is routed.
To view Service Domain status where Istio is used, click Deployments .
1. List of Service Domains where the service is deployed and status.
  - PROVISIONED. The service has been successfully installed and enabled.
  - PROVISIONING. The service initialization and provisioning state is in progress.
  - UNPROVISIONED. The service has been successfully disabled (uninstalled).
  - FAILED. The service provisioning has failed.
2. Alerts. Number of Critical (red) and Warning (yellow) alerts.
To see all alerts associated with the controller for this project, click Alerts .

Prometheus Application Monitoring and Metrics as a Service

Note: When you disable Prometheus and then later enable it, the service creates a new PersistentVolumeClaim (PVC) and clears any previously-stored metrics data stored in PVC.

The Prometheus service included with Karbon Platform Services enables you to monitor endpoints you define in your project's Kubernetes apps. Karbon Platform Services allows one instance of Prometheus per project.

Prometheus collects metrics in your app endoints. The Prometheus Deployments dashboard displays Service Domains where the service is deployed, service status, endpoints, and alerts. See Viewing Prometheus Service Status.

You can then decide how to view the collected metrics, through graphs or other Prometheus-supported means. See Create Prometheus Graphs with Grafana - Example.

Default Service Settings

Table 1. Prometheus Default Settings
Setting	Default Value or Description
Frequency interval to collect and store metrics (also known as scrape and store)	Every 60 seconds ¹
Collection endpoint	`/metrics` ¹
Default collection app	collect-metrics
Data storage retention time	10 days
You can create a customized `ServiceMonitor` YAML snippet to change this default setting. See Enable Prometheus App Monitoring and Metric Collection - Examples.

Enable Prometheus App Monitoring and Metric Collection - Examples

Monitor an Application with Prometheus - Default Endpoint

This sample app YAML specifies an app named metricsmatter-sample-app and creates one instance of this containerized app ( replicas: 1 ) from the managed Amazon Elastic Container Registry.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: metricsmatter-sample-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: metricsmatter-sample-app 
  template:
    metadata:
      name: metricsmatter-sample-app
      labels:
        app: metricsmatter-sample-app
    spec:
      containers:
        - name: metricsmatter-sample-app
          imagePullPolicy: Always
          image: 1234567890.dkr.ecr.us-west-2.amazonaws.com/app-folder/metricmatter_sample_app:latest

Next, in the same application YAML file, create a Service snippet. Add the default collect-metrics app label to the Service object. When you add app: collect-metrics , Prometheus scrapes the default /metrics endpoint every 60 seconds, with metrics exposed on port 8010.

---
apiVersion: v1
kind: Service
metadata:
  name: metricsmatter-sample-service
  labels:
    app: collect-metrics
spec:
  selector:
    app: metricsmatter-sample-app
  ports:
    - name: web
      protocol: TCP
      port: 8010

Monitor an Application with Prometheus - Custom Endpoint and Interval Example

Add a ServiceMonitor snippet to the app YAML above to customize the endpoint to scrape and change the interval to collect and store metrics. Make sure you include the Deployment and Service snippets.

Here, change the endpoint to /othermetrics and the collection interval to 15 seconds ( 15s ).

Prometheus discovers all ServiceMonitors in a given namespace (that is, each project app) where it is installed.

---
apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
 name: metricsmatter-sample-app
 labels:
   app: collect-metrics
spec:
 selector:
   matchLabels:
     app: collect-metrics
 endpoints:
   - path: /othermetrics
     interval: 15s
     port: 8010

Use Environment Variables as the Endpoint

You can also use endpoint environment variables in an application template for the service and AlertManager.

{{.Services.Prometheus.Endpoint}} defines the service endpoint.
{{.Services.AlertManager.Endpoint}} defines a custom Alert Manager endpoint.

Configure Service Domain Environment Variables describes how to use these environment variables.

Viewing Prometheus Service Status

The Prometheus Deployments dashboard displays Service Domains where the service is deployed, service status, Prometheus endpoints, and alerts.

Procedure

Click the menu button, then click Projects .
Click a project in the list.
The project dashboard is displayed along with Edit and Manage Services buttons.
Click Prometheus to view the default Deployments page.
1. Service Domain and Status. Service Domains where the Prometheus service is deployed and status.
  - PROVISIONED. The service has been successfully installed and enabled.
  - PROVISIONING. The service initialization and provisioning state is in progress.
  - UNPROVISIONED. The service has been successfully disabled (uninstalled).
  - FAILED. The service provisioning has failed.
2. Prometheus Endpoints. Endpoints that the service is scraping, by ID.
3. Alert Manager. Alert Manager shows alerts associated with the Prometheus endpoints, by ID.
4. Alerts. Number of Critical (red) and Warning (yellow) alerts.
To see all alerts associated with Prometheus for this project, click Alerts .

Create Prometheus Graphs with Grafana - Example

This example shows how you can set up a Prometheus metrics dashboard with Grafana.

This topic provides examples to help you expose Prometheus endpoints to Grafana, an open-source analytics and monitoring visualization application. You can then view scraped Prometheus metrics graphically.

Define Prometheus as the Data Source for Grafana

The first ConfigMap YAML snippet example uses the environment variable {{.Services.Prometheus.Endpoint}} to define the service endpoint. If this YAML snippet is part of an application template created by an infra admin, a project user can then specify these per-Service Domain variables in their application.

The second snippet provides configuration information for the Grafana server web page. The host name in this example is woodkraft2.ntnxdomain.com


apiVersion: v1
kind: ConfigMap
metadata:
 name: grafana-datasources
data:
 prometheus.yaml: |-

Define the Grafana Service and Use an Ingress Controller

Define the Grafana Service object to use port 3000 and an Ingress controller to manage access to the service (through woodkraft2.ntnxdomain.com).


apiVersion: v1
kind: Service
metadata:
  name: grafana
spec:
  selector:
    app: grafana
  ports:
    - port: 3000
      targetPort: 3000
---
apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: grafana
  labels:

          backend:
            serviceName: grafana
            servicePort: 3000

Kubernetes Apps

You can create intelligent applications to run on the Service Domain infrastructure or the cloud where you have pushed collected data. You can implement application YAML files to use as a template, where you can customize the template by passing existing Categories associated with a Service Domain to it.

You need to create a project with at least one user to create an app.

You can undeploy and deploy any applications that are running on Service Domains or in the cloud. See Deploying and Undeploying a Kubernetes Application.

Privileged Kubernetes Apps

Important: The privileged mode is deprecated. Nutanix plans to remove this feature in an upcoming release.

For Kubernetes apps running as privileged, you might have to specify the Kubernetes namespace where the application is deployed. You can do this by using the {{ .Namespace }} variable you can define in app YAML template file.

In this example, the resource kind of ClusterRoleBinding specifies the {{ .Namespace }} variable as the namespace where the subject ServiceAccount is deployed. As all app resources are deployed in the project namespace, specify the project name as well (here, name: my-sa).

apiVersion: v1
kind: ServiceAccount
metadata:
  name: my-sa
---
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: my-role-binding
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: my-cluster-role
subjects:
  - kind: ServiceAccount
    name: my-sa
    namespace: {{ .Namespace }}

Creating an Application

Create a Kubernetes application that you can associate with a project.

Before you begin

To complete this task, log on to the cloud management console.

About this task

If your app requires a service, make sure you enable it in the associated project.
Application YAML files can also be a template where you can customize the template by passing existing Categories associated with a Service Domain to it.
See also Configure Service Domain Environment Variables to set and use environment variables in your app.
Nutanix recommends that you do not reuse application names after creating and then deleting (removing) an application. If you subsequently create an application with the same name as a deleted application, your application might re-use stale data from the deleted application.

Procedure

From the home menu, click Projects , then click a project.
Click Kubernetes Apps > Create Kubernetes App .
Name your application. Up to 200 alphanumeric characters are allowed.
Description . Provide a relevant description for your application.

Click Kubernetes Apps , then select an application in the list.
Click Actions > Remove , then click Delete to confirm.
The Kubernetes Apps page lists any remaining applications.

Deploying and Undeploying a Kubernetes Application

You can undeploy and deploy any applications that are running on Service Domains or in the cloud. You can choose the Service Domains where you want the app to deploy or undeploy. Select the table or tile view on this page by clicking one of the view icons.

Before you begin

Undeploying a Kubernetes app deletes all config objects directly created for the app, including PersistentVolumeClaim data. Your app can create a PersistentVolumeClaim indirectly through StatefulSets. The following points describe scenarios when data is deleted and when data is preserved after you undeploy an app.

If your application specifies an explicit PersistentVolumeClaim object, when the app is undeployed, data stored in PersistentVolumeClaim is deleted. This data is not available if you then deploy the app.
If your application specifies a VolumeClaimTemplates object, when the app is undeployed, data stored in PersistentVolumeClaim persists. This data is available for reuse if you later deploy the app. If you plan to redeploy apps, Nutanix recommends using VolumeClaimTemplates to implement StatefulSets with stable storage.

Procedure

From the home menu, click Projects , then click a project.
Click Kubernetes Apps , then select an application in the list.
To undeploy a running application, select an application, then click Actions > Undeploy

Helm Chart Support and Requirements

Helm Chart Format

When you create a Kubernetes app in the cloud management console, you can upload a Helm chart package in a gzipped TAR file (.TGZ format) that describes your app. For example, it can include:

Helm chart definition YAML file
App YAML template files that define your application (deployment, service, and so on). See also Privileged Kubernetes Apps
Values YAML file where you declare variables to pass to your app templates. For example, you can specify Ingress controller annotations, cloud repository details, and other required settings

Supported Helm Version

Karbon Platform Services supports Helm version 3.

Kubernetes App Support: Karbon Platform Services supports the same Kubernetes resources in Helm charts as in application YAML files. For example, daemonsets, deployment, secrets, services, statefulsets, and so on are supported when defined in a Helm chart.

Data Pipelines

The Data Pipelines page enables you to create and view data pipelines, and also see any alerts associated with existing pipelines.

A data pipeline is a path for data that includes:

Input . An existing data source or real-time data stream.
Transformation . Code block such as a script defined in a Function to process or transform input data.
Output . A destination for your data. Publish data to the Service Domain, cloud, or cloud data service (such as AWS Simple Queue Service).

It also enables you to process and transform captured data for further consumption or processing.

To create a data pipeline, you must have already created or defined at least one of the following:

Project
Category
Data source
Function
Cloud profile. Required for cloud data destinations or Service Domain endpoints

When you create, clone, or edit a function, you can define one or more parameters. When you create a data pipeline, you define the values for the parameters when you specify the function in the pipeline.
Data pipelines can share functions, but you can specify unique parameter values for the function in each data pipeline.

Creating a Log Collector for Log Forwarding - Command Line

Create a log collector for log forwarding by using the kps command line.

Nutanix has released the kps command line on its public Github channel. https://github.com/nutanix/karbon-platform-services/tree/master/cli describes how to install the command line and includes sample YAML files for use with applications, data pipelines, data sources, and functions.

Each sample YAML file defines a log collector. Log collectors can be:

Infrastructure-based: collects infrastructure-related (Service Domain) information. For use by infra admins.
Project-based: project-related information (applications, data pipelines, and so on). For use by project users and infra admins (with assigned projects).

See the most up-to-date sample YAML files and descriptions at https://github.com/nutanix/karbon-platform-services/tree/master/cli.

Stream Real-Time Application and Pipeline Logs

Real-Time Log Monitoring built into Karbon Platform Services provides real-time log monitoring and lets you view application and data pipeline log messages securely in real time.

Note: Infrastructure administrators can stream logs if they have been added to a project.

Viewing the most recent log messages as they occur helps you see and troubleshoot application or data pipeline operations. Messages stream securely over an encrypted channel and are viewable only by authenticated clients (such as an existing user logged on to the Karbon Platform Services cloud platform).

The cloud management console shows the most recent log messages, up to 2 MB. To get the full logs, collect and then download the log bundles by Running Log Collector - Service Domains.

Displaying Real-Time Logs

View the most recent real-time logs for applications and data pipelines.

About this task

To complete this task, log on to the cloud management console.

Procedure

Go to the Deployments page for an application or data pipeline.
1. From the home menu, click Projects , then click a project.
2. Click Kubernetes Apps or Functions and Data Pipelines .
3. Click an app name or data pipeline name, then click Deployments .
4. Click an application or a data pipeline in the table, then click Deployments .
  A table shows each Service Domain deploying the application or data pipeline.
Select a Service Domain, then click View Real-time Logs .
The window displays streaming log messages and shows the most recent 2 MB of log messages from a container associated with your data pipeline function or application, from the Service Domain.

What to do next

: Real-Time Log Monitoring Console describes what you see in the terminal-style display.

Real-Time Log Monitoring Console

The Karbon Platform Services real-time log monitoring console is a terminal-style display that streams log entries as they occur.

After you do the steps in Displaying Real-Time Logs, a terminal-style window is displayed in one or more tabs. Each tab is streaming log messages and shows the most recent 2 MB of log messages from a container associated with your data pipeline function or application.

Your application or data pipeline function generates the log messages. That is, the console shows log messages that you have written into your application or function.

One or more tabs with a terminal style display shows messages generated by your application or function.

No Logs Message

If your Karbon Platform Services Service Domain is connected and your application or function is not logging anything, the console might show a No Logs message. In this case, the message means that the application or function is idle and not generating any log messages.

Errors

You might see one or more error messages in the following cases. As a result, Real-Time Log Monitoring cannot retrieve any logs.

If your application, function, or other resource fails
Network connectivity fails or is highly intermittent between the Karbon Platform Services Service Domain or your browser and karbon.nutanix.com

Tips for Real-Time Log Monitoring for Applications

The first tab shows the first container associated with the application running on the Karbon Platform Services Service Domain. The console shows one tab for each container associated with the application, including a tab for each container replicated in the same application.
Each tab displays the application and container name as app_name : container_id ) and might be truncated. To see the full name on the tab, hover over it.
Reordering tabs is not available. Unlike your usual tabbed browser experience, you cannot reorder or move the tabs.

Tips for Real-Time Log Monitoring for Functions in Data Pipelines

The first tab shows the first function deployed in the data pipeline running on the Service Domain. The console shows one tab for each function deployed in the data pipeline.
Reordering tabs is not available. Unlike your usual tabbed browser experience, you cannot reorder or move the tabs. For data pipelines, the displayed tab order is the order of the functions (that is, scripts of transformations) in the data pipeline.
Duplicate function names. If you use the same function more than once in the data pipeline, you will see duplicate tabs. That is, one tab for each function instance.
Each tab displays the data pipeline and function name as data_pipeline_ : function ) and might be truncated. To see the full name on the tab, hover over it.

Configure Service Domain Environment Variables

Define environment variables for an individual Service Domain. After defining them, any Kubernetes app that specifies that Service Domain can access them as part of a container spec in the app YAML.

As an infrastructure administrator, you can set environment variables and associated values for each Service Domain, which are available for use in Kubernetes apps. For example:

You can provide environment variables and values by using a Helm chart you upload when you create an app. See Creating an Application and Helm Chart Support and Requirements.
You can also set specific environment variables per Service Domain by updating a Service Domain in the cloud management console or by using the kps update svcdomain command line.
See also Privileged Kubernetes Apps.

As a project user, you can then specify these per-Service Domain variables set by the infra admin in your app. If you do not include the variable name in your app YAML file but you pass it as a variable to run in your app, Karbon Platform Services can inject this variable value.

Setting and Clearing Service Domain Environment Variables - Command Line

How to set environment variables for a Service Domain.

Before you begin

You must be an infrastructure admin to set variables and values.

Procedure

Install the kps command line as described at GitHub: https://github.com/nutanix/karbon-platform-services/tree/master/cli
From your terminal window, create a Karbon Platform Services context to associate with an existing infra admin user.
```
user@host$  kps config create-context context_name --email user_email_address --password password
```
1. context_name . A context name to associate with the specified user_email_address and related Karbon Platform Services resources.
2. user_email_address . Email address of an existing Karbon Platform Services user. This email address can be a My Nutanix account address or local user address.
3. password . Password for the Karbon Platform Services user.
Verify that the context is created.
```
user@host$ kps config get-contexts
```
The terminal displays CURRENT CONTEXT as the context_name . It also displays the NAME, URL, TENANT-ID, and Karbon Platform Services email and password.
Get the Service Domain names (displayed in YAML format) to find the service domain where you set the environment variables.
```
user@host$ kps get svcdomain -o yaml
```
For a Service Domain named my-svc-domain , for example, set the Service Domain environment variable. In this example, set a secret variable named SD_PASSWORD with a value of passwd1234 .
```
user@host$ kps update svcdomain my-svc-domain --set-env '{"SD_PASSWORD":"passwd1234"}'
```
Verify the changes.
```
user@host$ kps get svcdomain my-svc-domain -o yaml
```
```
kind: edge
name: my-svc-doamin
connected: true
.
.
.
env: '{"SD_PASSWORD": "passwd1234"}'
```
The Service Domain is updated. Any infra admin or project user can deploy an app to a Service Domain where you can refer to the secret by using the variable $(SD_PASSWORD) .
You can continue to add environment variables by using the kps update svcdomain my-svc-domain --set-env '{" variable_name ": " variable_value "}' command.
You an also clear one or all variables for Service Domain svc_domain_name .
1. To clear (unset) all environment variables:
```
user@host$ kps update svcdomain svc_domain_name --unset-env
```
2. To clear (unset) a specific environment variables:
```
user@host$ kps update svcdomain svc_domain_name --unset-env '{"variable_name":"variable_value"}'
```
To update an app, restart it. See also Deploying and Undeploying a Kubernetes Application.

What to do next

Using Service Domain Environment Variables - Example

Example: how to use existing environment variables for a Service Domain in application YAML.

About this task

You must be an infrastructure admin to set variables and values. See Setting and Clearing Service Domain Environment Variables - Command Line.
In this example, an infra admin has created these environment variables: a Kafka endpoint that requires a secret (authentication) to authorize the Kafka broker.
As a project user, you can then specify these per-Service Domain variables set by the infra admin in your app. If you do not include the variable name in your app YAML file but you pass it as a variable to run in your app, Karbon Platform Services can inject this variable value.

Procedure

In your app YAML, add a container snippet similar to the following.


apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-app-deployment
  labels:
    app: my-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      containers:
      - name: my-app
        image: some.container.registry.com/myapp:1.7.9
        ports:
        - containerPort: 80
     env:
        - name: KAFKA_ENDPOINT
          value: some.kafka.endpoint
        - name: KAFKA_KEY
        - value: placeholder
     command:
       - sh
       - c

Use this app YAML snippet when you create a Kubernetes app in Karbon Platform Services as described in Kubernetes Apps.

Karbon Platform Services Terminology

Category

Logically grouped Service Domain, data sources, and other items. Applying a category to an entity applies any values and attributes associated with the category to the entity.

Cloud Connector

Built-in Karbon Platform Services platform feature to publish data to a public cloud like Amazon Web Services or Google Cloud Platform. Requires a customer-owned secured public cloud account and configuration in the Karbon Platform Services management console.

Cloud Profile

Cloud provider service account (Amazon Web Services, Google Cloud Platform, and so on) where acquired data is transmitted for further processing.

Container Registry Profile

Credentials and location of the Docker container registry hosted on a cloud provider service account. Can also be an existing cloud profile.

Data Pipeline

Path for data that includes input, processing, and output blocks. Enables you to process and transform captured data for further consumption or processing.

Input. An existing data stream or data source, identified according to a Category
Transformation. Code block such as a script defined in a Function to process or transform input data.
Output. A destination for data. Publish data to the cloud or cloud service (such as AWS Simple Queue Service) at the edge.

Data Service

Data service such as Kafka as a Service or Real-Time Stream Processing as a Service.

Data Source

A collection of sensors, gateways, or other input devices to associate with a node or Service Domain (previously known as an edge). Enables you to manage and monitor sensor integration and connectivity.

A node minimally consists of a node (also known as edge device) and a data source. Any location (hospital, parking lot, retail store, oil rig, factory floor, and so on) where sensors or other input devices are installed and collecting data. Typical sensors measure (temperature, pressure, audio, and so on) or stream (for example, an IP-connected video camera).

Functions

Code used to perform one or more tasks. A script can be as simple as text processing code or it could be advanced code implementing artificial intelligence, using popular machine learning frameworks like Tensorflow.

Infrastructure Administrator

User who creates and administers most aspects of Karbon Platform Services. The infrastructure administrator provisions physical resources, Service Domains, data sources and public cloud profiles. This administrator allocates these resources by creating projects and assigning project users to them.

Project

A collection of infrastructure (Service Domain, data source, project users) plus code and data (Kubernetes apps, data pipelines, functions, run-time environments), created by the infrastructure administrator for use by project users.

Project User

User who views and uses projects created by the infrastructure administrator. This user can view everything that an infrastructure administrator assigns to a project. Project users can utilize physical resources, as well as deploy and monitor data pipelines and applications. This user has project-specific CRUD permissions: the project user can create, read, update, and delete assigned applications, scripts, data pipelines, and other project users.

Real-time Data Stream

Data Pipeline output endpoint type with a Service Domain as an existing destination.
An existing data pipeline real-time data stream that is used as the input to another data pipeline.

Run-time Environment

A run-time environment is a command execution environment to run applications written in a particular language or associated with a Docker registry or file.

Service Domain

Intelligent Platform as a Service (PaaS) providing the Karbon Platform Services Service Domain infrastructure (consisting of a full software stack combined with a hardware device). It enables customers to deploy intelligent applications (powered by AI/artificial intelligence) to process and transform data ingested by sensors. This data can be published selectively to public clouds.

Karbon Platform Services Management Console

Browser-based console where you can manage the Karbon Platform Services platform and related infrastructure, depending on your role (infrastructure administrator or project user).

Karbon Platform Services

Software as a Service (SaaS)/Platform as a Service (PaaS) based management platform and cloud IoT services. Includes the Karbon Platform Services management console.

Last updated: 2022-11-24

Karbon Platform Services Overview

With Karbon Platform Services, you can:

Quickly build and deploy intelligent applications across a public or private cloud infrastructure.
Connect various mobile, highly distributed data sensors (like video cameras, temperature or pressure sensors, streaming devices, and so on) to help collect data.
Create intelligent applications using data connectors and machine learning modules (for example, implementing object recognition) to transform the data. An application can be as simple as text processing code or it could be advanced code implementing AI by using popular machine learning frameworks like TensorFlow.
Push this data to your Service Domain or the public cloud to be stored or otherwise made available.

Cloud Management Console and User Experience

Admin Console drop-down menu for infra admins and Home Console drop-down menu for project users. Both menus provide a list of all current projects and 1-click access to an individual project. In the navigation sidebar, Projects also provides a navigation path to the overall list of projects.
Vertical tabs for most pages and dashboards. For example, clicking Administration > Logging shows the Logging dashboard with related task and Alert tabs. The left navigation menu remains persistent to help eliminate excessive browser refreshes and help overall navigation.
Simplified Service Domain Management . In addition to the standard Service Domain list showing all Service Domains, a consolidated dashboard for each Service Domain is available from Infrastructure > Service Domain . Karbon Platform Services also simplifies upgrade operations available from Administration > Upgrades . For convenience, infra admins can choose when to download available versions to all or selected Service Domains, when to upgrade them, and check status for all or individual Service Domains.
Updated Workflows for Infrastructure Admins and Project Users . Apart from administration operations such as Service Domain, user management, and resource management, the infra admin and project user work flow is project-centric. A project encapsulates everything required to successfully implement and monitor the platform.
Updated GPU/vGPU Configuration Support . If your Service Domain includes access to a GPU/vGPU, you can choose its use case. When you create or update a Service Domain, you can specify exclusive access by any Kubernetes app or data pipeline or by the AI Inferencing API (for example, if you are using ML Models).

Project User Role

Karbon Platform Services allows and defines two user types: an infrastructure administrator and a project user. An infrastructure administrator can create both user types.

The project user has project-specific create/read/update/delete (CRUD) permissions: the project user can create, read, update, and delete the following and associate it with an existing project:

Kubernetes Apps
Functions (scripts)
Data pipelines
Runtime environments

When an infrastructure administrator adds another infrastructure administrator as a user to a project, that administrator is assigned the project user role for that project.

Viewing Dashboards

Quick Start Menu

Getting Started - Project User

The Quick Start Menu lists the common onboarding tasks for the project user. It includes links to project resource pages. You can also go directly to any project resource from the Apps & Data menu item.

As the project user, you can update a project by creating the following items.

Applications
Data pipelines
Runtime environments
Functions

If any Getting Started item shows Pending , the infrastructure administrator has not added you to that entity (like a project or application) or you need to create an entity (like an application).

Start At The Project Page

To get started after logging on to the cloud management console, see Projects.

Projects

A project is an infrastructure, apps, and data collection created by the infrastructure administrator for use by project users.

A project can consist of:

Existing administrator or project users
A Service Domain
Cloud profile
Container registry profile

When you add a Service Domain to a project, all resources such as data sources associated with the Service Domain are available to the users added to the project.

Projects Page

The Projects page lets an infrastructure administrator create a new project and lists projects that administrators can update and view.

When you click a project name, the project Summary dashboard is displayed and shows resources in the project.

Managing Project Services

The Karbon Platform Services cloud infrastructure provides services that are enabled by default. It also provides access to services that you can enable for your project.

The platform includes these ready-to-use services, which provide an advantage over self-managed services:

Secure by design.
No life cycle management. Service Domains do not require any user intervention to maintain or update service versions, patches, or other hands-on activities. For ease of use, all projects using the Service Domain use the same service version.
Dedicated service resources. Your project uses isolated service resources. Service resources are not shared with other projects. Applications within a project are not required to authenticate to use the service.
Service-specific alerts. Like other Karbon Platform Services features, the Service Domain helps monitor service health and raises service-specific alerts.

App Runtime Services

These services are enabled by default on each Service Domain.

Kubernetes Apps. Containers as a service. You can create and run Kubernetes apps without having to manage the underlying infrastructure.
Functions and Data Pipelines. Run server-less functions based on data triggers, then publish data to specific cloud or Service Domain endpoints.
AI Inferencing. Enable this service to use your machine learning (ML) models in your project. The ML Model feature provides a common interface for functions (that is, scripts) or applications.

Ingress Controller

Service Mesh

Istio. Provides secure connection, traffic management, and telemetry. See Istio Service Mesh.

Data Streaming | Messaging

Kafka. Available for use within project applications and data pipelines, running on a Service Domain hosted in your environment. See Kafka as a Service.
NATS. Available for use within project applications and data pipelines. In-memory high performance data streaming including pub/sub (publish/subscribe) and queue-based messaging.

Logging | Monitoring | Alerting

Prometheus. Provides Kubernetes app monitoring and logging, alerting, metrics collection, and a time series data model (suitable for graphing). See Prometheus Application Monitoring and Metrics as a Service.
Logging. Provides log monitoring and log bundling. See Audit Trail and Log Management.

Kafka as a Service

Kafka is available as a data service through your Service Domain.

Secure by design.
No need to explicitly declare Kafka topics. With Karbon Platform Services Kafka as a service, topics are automatically created.
No life cycle management. Service Domains do not require any user intervention to maintain or update service versions, patches, or other hands-on activities. For ease of use, all projects using the Service Domain use the same service version.
Dedicated service resources. Your project uses isolated service resources. Service resources are not shared with other projects. Applications within a project are not required to authenticate to use the service.
Service-specific alerts. Like other Karbon Platform Services features, the Service Domain monitors service health and raises service-specific alerts.

Using Kafka in an Application

Information about application requirements and sample YAML application file

Create an application for your project as described in Creating an Application and specify the application attributes and configuration in a YAML file.

Sample Kafka Application YAML Template File


apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-app-deployment
  labels:
    app: my-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      containers:
      - name: my-app
        image: some.container.registry.com/myapp:1.7.9
        ports:
        - containerPort: 80
     env:
        - name: KAFKA_ENDPOINT
          value: {{.Services.Kafka.Endpoint}}


Field Name	Value or Field Name / Description	Value or Field Name / Description
`kind`	`Deployment`	Specify the resource type. Here, use `Deployment` .
`metadata`	`name`	Provide a name for your deployment.
	`labels`	Provide at least one label. Here, specify the application name as `app: my-app`
`spec`		Define the Kafka service specification.
	`replicas`	Here, 1 to indicate a single Kafka cluster (single Service Domain instance or VM) to keep data synchronized.
	`selector`	Use `matchLabels` and specify the `app` name as in `labels` above.
	`template`
		Specify the application name here ( `my-app` ), same as `metadata` specifications above.
	`spec`	Here, define the specifications for the application using Kafka.
	`containers`	`name: my-app` . Specify the container application `image: some.container.registry.com/myapp:1.7.9` . Define the container registry host address where the container image is stored. `ports: containerPort: 80` . Define the container registry port. Here, 80.
	`env`	`name: KAFKA_ENDPOINT` `value: {{.Services.Kafka.Endpoint}}` Leave these values as shown.

Using Kafka in a Function for a Data Pipeline

Information about data pipeline function requirements.

See Functions and Data Pipelines.

You can specify a Kafka endpoint type in a data pipeline. A data pipeline consists of:

Input. An existing data source or real-time data stream (output from another data pipeline).
Transformation. A function (code block or script) to transform data from a data source (or no function at all to pass data directly to the endpoint).
Output. An endpoint destination for the transformed or raw data.

Kafka Endpoint Function Requirements

For a data pipelines with a Kafka topic endpoint:

Language . Select the golang scripting language for the function.
Runtime Environment . Select the golang runtime environment for the function. A default runtime environment is already selected in most cases depending on the Language you have selected.

Viewing Kafka Status

Procedure

Click the menu button, then click Projects .
Click a project in the list.
The project dashboard is displayed along with Edit and Manage Services buttons.
Click Kafka .
This dashboard shows a consolidated, high-level view of all Kafka topics, deployments, and related alerts. The default view is Topics.
To show all topics for this project, click Topics .

2. Brokers. A No Brokers Available message might mean the Service Domain is not connected.
3. Alerts. Number of Critical (red) and Warning (yellow) alerts.
To see all alerts associated with Kafka for this project, click Alerts .

Enable an Ingress Controller

The Service Domain supports the Traefik open source router as the default Kubernetes Ingress controller. You can also choose the NGINX ingress controller instead.

When you include Ingress controller annotations as part of your application YAML file, Karbon Platform Services uses Traefik as the default on-demand controller.

If your deployment requires it, you can alternately use NGINX (ingress-nginx) as a Kubernetes Ingress controller instead of Traefik.

In your application YAML, specify two snippets:

Service snippet. Use annotations to define the HTTP or HTTPS host protocol, path, service domain, and secret for each Service Domain to use as an ingress controller. You can specify one more Service Domains.
Secret snippet. Use this snippet to specify the certificates used to secure app traffic.

Sample Ingress Controller Service Domain Configuration

To securely route application traffic with a Service Domain ingress controller, create YAML snippets to define and specify the ingress controller for each Service Domain.

You can only enable and use one Ingress controller per Service Domain.

Add the Istio Virtual Service and DestinationRules to an Application - Example

In the application YAML snippet or file, define the VirtualService and DestinationRules objects.

These objects specify traffic routing rules for the recommendation-service app host. If the traffic rules match, traffic flows to the named destination (or subset/version of it) as defined here.

apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: recomm-svc
spec:
  hosts:
  - recommendation-service
  http:
  - match:
    - headers:
        user-agent:
          regex: .*Firefox.*
    route:
    - destination:
        host: recommendation-service
        subset: v2
  - route:
    - destination:
        host: recommendation-service
        subset: v1

This DestinationRule YAML snippet defines a load-balancing traffic policy for the policy versions ( subsets ), where any healthy host can service the request.

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: recomm-svc
spec:
  host: recommendation-service
  trafficPolicy:
    loadBalancer:
      simple: RANDOM
  subsets:
  - name: v1
    labels:
      version: v1
  - name: v2
    labels:
      version: v2

Manage Traffic by Weight - Example

In this YAML snipped, you can split traffic for each subset by specifying a weight of 30 in one case, and 70 in the other. You can also weight them evenly by giving each a weight value of 50.

apiVersion: networking.istio.io/v1beta1
kind: VirtualService
metadata:
  name: recomm-svc
spec:
  hosts:
  - recommendation-service
  http:
  - route:
    - destination:
       host: recommendation-service
       subset: v2
      weight: 30   
    - destination:
       host: recommendation-service
       subset: v1
      weight: 70

Data Pipelines

The Data Pipelines page enables you to create and view data pipelines, and also see any alerts associated with existing pipelines.

A data pipeline is a path for data that includes:

Input . An existing data source or real-time data stream.
Transformation . Code block such as a script defined in a Function to process or transform input data.
Output . A destination for your data. Publish data to the Service Domain, cloud, or cloud data service (such as AWS Simple Queue Service).

It also enables you to process and transform captured data for further consumption or processing.

To create a data pipeline, you must have already created or defined at least one of the following:

Project
Category
Data source
Function
Cloud profile. Required for cloud data destinations or Service Domain endpoints

When you create, clone, or edit a function, you can define one or more parameters. When you create a data pipeline, you define the values for the parameters when you specify the function in the pipeline.
Data pipelines can share functions, but you can specify unique parameter values for the function in each data pipeline.
You can also stop and start a data pipeline. See Stopping and Starting a Data Pipeline.

Data Pipeline Visualization

After you create one or more data pipelines, the Data Pipelines > Visualization page shows data pipelines and the relationship among data pipeline components.

Stream Real-Time Application and Pipeline Logs

Real-Time Log Monitoring built into Karbon Services provides real-time log monitoring and lets you view application and data pipeline log messages securely in real time.

Note: Infrastructure administrators can stream logs if they have been added to a project.

The cloud management console shows the most recent log messages, up to 2 MB.

Displaying Real-Time Logs

View the most recent real-time logs for applications and data pipelines.

About this task

To complete this task, log on to the cloud management console.

Procedure

Go to the Deployments page for an application or data pipeline.
1. From the home menu, click Projects , then click a project.
2. Click Kubernetes Apps or Functions and Data Pipelines .
3. Click an app name or data pipeline name, then click Deployments .
4. Click an application or a data pipeline in the table, then click Deployments .
  A table shows each Service Domain deploying the application or data pipeline.
Select a Service Domain, then click View Real-time Logs .
The window displays streaming log messages and shows the most recent 2 MB of log messages from a container associated with your data pipeline function or application, from the Service Domain.

What to do next

: Real-Time Log Monitoring Console describes what you see in the terminal-style display.

Real-Time Log Monitoring Console

The Karbon Platform Services real-time log monitoring console is a terminal-style display that streams log entries as they occur.

Your application or data pipeline function generates the log messages. That is, the console shows log messages that you have written into your application or function.

No Logs Message

Errors

You might see one or more error messages in the following cases. As a result, Real-Time Log Monitoring cannot retrieve any logs.

If your application, function, or other resource fails
Network connectivity fails or is highly intermittent between the Karbon Platform Services Service Domain or your browser and karbon.nutanix.com

Tips for Real-Time Log Monitoring for Applications

The first tab shows the first container associated with the application running on the Karbon Platform Services Service Domain. The console shows one tab for each container associated with the application, including a tab for each container replicated in the same application.
Each tab displays the application and container name as app_name : container_id ) and might be truncated. To see the full name on the tab, hover over it.
Reordering tabs is not available. Unlike your usual tabbed browser experience, you cannot reorder or move the tabs.

Tips for Real-Time Log Monitoring for Functions in Data Pipelines

The first tab shows the first function deployed in the data pipeline running on the Service Domain. The console shows one tab for each function deployed in the data pipeline.
Reordering tabs is not available. Unlike your usual tabbed browser experience, you cannot reorder or move the tabs. For data pipelines, the displayed tab order is the order of the functions (that is, scripts of transformations) in the data pipeline.
Duplicate function names. If you use the same function more than once in the data pipeline, you will see duplicate tabs. That is, one tab for each function instance.
Each tab displays the data pipeline and function name as data_pipeline_ : function ) and might be truncated. To see the full name on the tab, hover over it.

Configure Service Domain Environment Variables

Define environment variables for an individual Service Domain. After defining them, any Kubernetes app that specifies that Service Domain can access them as part of a container spec in the app YAML.

As an infrastructure administrator, you can set environment variables and associated values for each Service Domain, which are available for use in Kubernetes apps. For example:

You can provide environment variables and values by using a Helm chart you upload when you create an app. See Creating an Application and Helm Chart Support and Requirements.
You can also set specific environment variables per Service Domain by updating a Service Domain in the cloud management console or by using the kps update svcdomain command line.
See also Privileged Kubernetes Apps.

Setting and Clearing Service Domain Environment Variables - Command Line

How to set environment variables for a Service Domain.

Before you begin

You must be an infrastructure admin to set variables and values.

Procedure

Install the kps command line as described at GitHub: https://github.com/nutanix/karbon-platform-services/tree/master/cli
From your terminal window, create a Karbon Platform Services context to associate with an existing infra admin user.
```
user@host$  kps config create-context context_name --email user_email_address --password password
```
1. context_name . A context name to associate with the specified user_email_address and related Karbon Platform Services resources.
2. user_email_address . Email address of an existing Karbon Platform Services user. This email address can be a My Nutanix account address or local user address.
3. password . Password for the Karbon Platform Services user.
Verify that the context is created.
```
user@host$ kps config get-contexts
```
The terminal displays CURRENT CONTEXT as the context_name . It also displays the NAME, URL, TENANT-ID, and Karbon Platform Services email and password.
Get the Service Domain names (displayed in YAML format) to find the service domain where you set the environment variables.
```
user@host$ kps get svcdomain -o yaml
```
For a Service Domain named my-svc-domain , for example, set the Service Domain environment variable. In this example, set a secret variable named SD_PASSWORD with a value of passwd1234 .
```
user@host$ kps update svcdomain my-svc-domain --set-env '{"SD_PASSWORD":"passwd1234"}'
```
Verify the changes.
```
user@host$ kps get svcdomain my-svc-domain -o yaml
```
```
kind: edge
name: my-svc-doamin
connected: true
.
.
.
env: '{"SD_PASSWORD": "passwd1234"}'
```
The Service Domain is updated. Any infra admin or project user can deploy an app to a Service Domain where you can refer to the secret by using the variable $(SD_PASSWORD) .
You can continue to add environment variables by using the kps update svcdomain my-svc-domain --set-env '{" variable_name ": " variable_value "}' command.
You an also clear one or all variables for Service Domain svc_domain_name .
1. To clear (unset) all environment variables:
```
user@host$ kps update svcdomain svc_domain_name --unset-env
```
2. To clear (unset) a specific environment variables:
```
user@host$ kps update svcdomain svc_domain_name --unset-env '{"variable_name":"variable_value"}'
```
To update an app, restart it. See also Deploying and Undeploying a Kubernetes Application.

What to do next

Using Service Domain Environment Variables - Example

Example: how to use existing environment variables for a Service Domain in application YAML.

About this task

You must be an infrastructure admin to set variables and values. See Setting and Clearing Service Domain Environment Variables - Command Line.
In this example, an infra admin has created these environment variables: a Kafka endpoint that requires a secret (authentication) to authorize the Kafka broker.
As a project user, you can then specify these per-Service Domain variables set by the infra admin in your app. If you do not include the variable name in your app YAML file but you pass it as a variable to run in your app, Karbon Platform Services can inject this variable value.

Procedure

In your app YAML, add a container snippet similar to the following.


apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-app-deployment
  labels:
    app: my-app
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-app
  template:
    metadata:
      labels:
        app: my-app
    spec:
      containers:
      - name: my-app
        image: some.container.registry.com/myapp:1.7.9
        ports:
        - containerPort: 80
     env:
        - name: KAFKA_ENDPOINT
          value: some.kafka.endpoint
        - name: KAFKA_KEY
        - value: placeholder
     command:
       - sh
       - c
       - "exec node index.js $(KAFKA_KEY)"

Use this app YAML snippet when you create a Kubernetes app in Karbon Platform Services as described in Kubernetes Apps.

License Manager Guide

Last updated: 2022-11-29

Welcome to License Manager

The Nutanix corporate web site includes up-to-date information about AOS software editions .

License Manager provides Licensing as a Service (LaaS) by integrating the Nutanix Support portal Licensing page with licensing management and agent software residing on Prism Element and Prism Central clusters. Unlike previous license schemes and work flows that were dependent on specific Nutanix software releases, License Manager is an independent software service residing in your cluster software. You can update it independently from Nutanix software such as AOS, Prism Central, Nutanix Cluster Check, and so on.

License Manager provides these features and benefits.

Simplified upgrade path. Upgradeable through Life Cycle Manager (LCM), which enables Nutanix to regularly introduce licensing features, functions, and fixes. Upgrades through LCM help ensure that your cluster is running the latest licensing agent logic.
Streamlined web console interface for Prism Element and Prism Central. After licensing unlicensed clusters and adding new software products through the Nutanix Support Portal, the web console provides a single 1-click control plane for most work flows. The web console only displays your licensed products and their current status.
Simplified 1-click work flow. Invisible integration with the Nutanix Support Portal helps simplify the most common licensing work flows and use cases.
Consistent experience. License Manager works for all licensable products that are available for Prism Element and Prism Central.

Licensing Management Options

License Manager provides more than one way to manage your licenses, depending on your preference and cluster deployment. Except for dark-site clusters, where AOS and Prism Central clusters are not connected to the Internet, these options require that your cluster is connected to the Internet.

Manage Licenses with License Manager and 1-Click Licensing

This feature is not available to dark site clusters, which are not connected to the Internet.

See Enable 1-Click Licensing and Manage Licenses with 1-Click Licensing.

Nutanix recommends that you configure and enable 1-click licensing. 1-click licensing simplifies license and add-on management by integrating the licensing work flow into a single interface in the web console. Once you enable this feature, you can perform most licensing tasks from the web console. It is disabled by default.

Depending on the product license you purchase, you apply it through the Prism Element or Prism Central web console. See Prism Element Cluster Licensing or Prism Central License Categories.

Manage Licenses with License Manager Without Enabling 1-Click Licensing (3-Step Licensing)

This feature is not available to dark site clusters, which are not connected to the Internet.

See Manage Licenses with Update License (3-Step Licensing).

After you license your cluster, the web console Licensing page allows you to manage your license tier by upgrading, downgrading, or otherwise updating a license. If you have not enabled 1-click licensing and want to use 3-step licensing, the Licensing page includes a Update License button.

Manage Licenses For Dark-Site Clusters

For legacy licenses (that is, licenses other than Nutanix cloud platform package licenses), see Manage Licenses for Dark Site Clusters (Legacy License Key).

For cloud platform package licenses, see Manage Licenses for Dark Site Clusters (Cloud Platform License Key).

Use these procedures if your dark site cluster is not connected to the Internet (that is, your cluster is deployed at a dark site). To enter dark site cluster information at the Nutanix Support Portal, these procedures require you to use a web browser from a machine connected to the Internet. If you do not have Internet access, you cannot use these procedures.

Nutanix Support Portal Licenses Page

This topic assumes that you already have user name and password credentials for the Nutanix Support portal.

After you log on to the Nutanix Support portal at https://portal.nutanix.com, click the Licenses link on the portal home page or the hamburger menu available from any page. Licenses provides access to these licensing landing pages:

Summary . Displays a license summary page with panes (widgets) for each type of license that you have purchased. Each pane specifies the tier type, usage percentage (how many you have used out of your total availability), and the metric for each type of license. Click the Manage Licenses button (top of page) to get started with new licenses or administer existing licenses.
License Inventory . Includes the following two license category pages.
- Active Licenses . Displays a table of active licenses for your account (default view for License Inventory ). Active licenses are purchased licenses that are usable currently. Entry information in the table varies by tab and includes license ID, tier, class, expiration date, and other information. If you are using tags, the portal displays tag names on the page, which you can use to Filter licenses. To download a comma-separated values file containing the details from the table, click Download all as CSV . You can also select one or more specific entries to download only the selected cluster license details. The table includes the following tabs that filter the list by status:
  - All : Lists all active licenses in your inventory.
  - Available : Lists licenses that are currently available to be provisioned to a cluster.
  - Applied : Lists licenses that are provisioned to an active cluster.
  - Upgrade : Lists purchased upgrade licenses. An upgrade license enables you to activate one or more features from a higher licensing tier without having to purchase completely new licenses. That is, you upgrade your existing unexpired lower tier license (for example, AOS Pro) with an upgrade license (AOS Ultimate). For each upgrade license, you must have an existing lower tier license to activate the upgrade license. As with future licenses, you cannot apply an upgrade license to a cluster until the Start Date has passed. See Upgrade Licenses.
  - Reserved (Nutanix Cloud Clusters only): Lists the licenses that you have partially or fully reserved for Nutanix Cloud Clusters. You can download the licensing details as a CSV file and manage the license reservations. You can also specify the capacity allocation for Nutanix Cloud Clusters (see Reserve Licenses for Nutanix Cloud Clusters).
  - Expiring : Lists licenses that will be expiring soon.
  - Future : Lists licenses that start at a future date and cannot be applied to clusters until the start date is in the past.
- Inactive Licenses . Displays a table of inactive licenses for your account. Inactive licenses are purchased licenses that have either expired or were decommissioned. Entry information includes license ID, expiration date, days since expiry, quantity, tier, class, PO number, and tag.
Clusters . Includes one or more of the following category pages depending on your account type. To download a comma-separated values file containing the details from any of the pages, click Download all as CSV . Click the Cluster UUID link to see cluster license details.
- Licensed Clusters . Displays a table of licensed clusters including the cluster name, cluster UUID, license tier, and license metric.
- Cloud Clusters . Displays a table of licensed Nutanix Cloud Clusters including the cluster name, cluster UUID, billing mode, and status.
- License with file . Displays a table of clusters licensed with a license summary file (LSF) including the cluster name, cluster UUID, license tier, and license metric.
- License with key . Displays a table of (usually dark site) clusters licensed with a license key including the cluster name, cluster UUID, license key, and license tags.
- Cluster Expirations . Displays a table that lists when a license will expire. Entries include the expiry date, days to expiration, cluster name, and cluster UUID. To filter the table, select the duration from the pull-down list in the View all clusters expiring in the next XX Days field.

Upgrading License Manager

License Manager is independent software and is therefore updated independently from Nutanix software such as AOS, Prism Central, Nutanix Cluster Check, and so on.

When upgrades are available, you can upgrade License Manager through Life Cycle Manager (LCM). LCM enables Nutanix to regularly introduce licensing features, functions, and fixes. Upgrades through LCM help ensure that your cluster is running the latest licensing agent logic.

Nutanix has also designed License Manager so that cluster node restarts are not required.

The Life Cycle Manager Guide describes how to perform an inventory and, if a new version is available, how to update a component like License Manager.

What Version Of License Manager Do I Have?

Log on to the Prism Element or Prism Central web console and do one of the following.

Click the gear icon, then select Licensing in the Settings panel. Under the gear icon, you can see the version. For example, LM.2021.7.2.

From the Home menu, click LCM > Inventory . Select View By > Component . The list shows the version. For example, LM.2021.7.2.

About Licenses

Products That Do Not Require a License

Not all Nutanix software products require a license. Nutanix provides these products and their features without requiring you to do anything license-wise:

Nutanix AHV
Karbon (enabled through Prism Central)
Prism Starter
Framework and utility software such as Life Cycle Manager (LCM), X-Ray, and Move
Foundation

Prism Element License Categories

See these Nutanix corporate web sites for the latest information about software licensing and the latest available platforms.

Nutanix Software Editions and AOS Software Licensing Models
Nutanix Hardware Platforms and Dynamic Specsheet

Nutanix generally categorizes licenses as follows.

Software-only

Platforms are qualified by Nutanix (NX Series) or by approved third-party vendors, such as HPE, Cisco, Dell, and others.
No license is embedded or delivered as a default, as you purchase hardware and licenses separately.
You can purchase AOS Starter, Pro, or Ultimate, and Add-On licenses.
Your purchased license metric is based on capacity based licensing (CBL), remote office/back office (ROBO), or virtual desktop infrastructure (VDI).
Licenses are transferable.

Third-party OEM

Includes OEM platforms qualified by Dell (Nutanix on Dell XC Series appliances and XC Core nodes), Lenovo (Lenovo HX Series Certified Nodes), and other vendors.
No license is embedded or delivered as a default, as you purchase hardware and licenses separately.
You can purchase AOS Starter, Pro, or Ultimate, and Add-On licenses.
Your purchased license metric is based on capacity based licensing (CBL), remote office/back office (ROBO), or virtual desktop infrastructure (VDI).
Licenses are transferable.

Prism Element Cluster Licensing

Licenses you can apply through the Prism Element web console include:

AOS Starter, Pro, and Ultimate Licenses

See Prism Element License Categories.

Software-only and third-party OEM platforms require you to download and install a Starter license file that you have purchased.

For all platforms: the AOS Pro and Ultimate license levels require you to install this license on your cluster. When you upgrade a license or add nodes or clusters to your environment, you must install the license.

If you enable 1-click licensing as described in Enable 1-Click Licensing, you can apply the license through the Prism Element web console without needing to log on to the support portal.

If you do not want to enable this feature, you can manage licenses as described in Manage Licenses with Update License (3-Step Licensing). This licensing workflow is also appropriate for dark-site (non-Internet connected or restricted connection) deployments.

Note: Legacy-licensed life of device Nutanix NX and OEM AOS Appliance platforms include an embedded Starter license as part of your purchase. It does not have to be downloaded and installed or otherwise applied to your cluster.

AOS Remote and Branch Office (ROBO) and Virtual Desktop Infrastructure per User (VDI) Licenses

The Nutanix corporate web site includes the latest information about these license models.

AOS Capacity-Based Licenses

Capacity-based licensing is the Nutanix licensing model where you purchase and apply licenses based on cluster attributes. Cluster attributes include the number of raw CPU cores and total raw Flash drive capacity in tebibytes (TiBs). See AOS Capacity-Based Licensing.

Add-Ons

You can add individual features known as add-ons to your existing license feature set. When Nutanix makes add-ons available, you can add them to your existing license, depending on the license level and add-ons available for that license.

See Add-On Licenses.

Prism Central License Categories

As the control console for managing multiple clusters, Prism (also known as Prism Central) consists of three license tiers. If you enable 1-click licensing as described in Enable 1-Click Licensing, you can apply licenses through the Prism web console without needing to log on to the support portal.

Licenses that are available or that you can apply through the Prism web console include:

Prism Starter

Default free Prism license, which enables you to register and manage multiple Prism Element clusters, upgrade Prism with 1-click through Life Cycle Manager (LCM), and monitor and troubleshoot managed clusters. You do not have to explicitly apply the Prism Starter license tier, which also never expires.

Prism Pro

Includes all Prism Starter features plus customizable dashboards, capacity, planning, and analysis tools, advanced search capabilities, low-code/no-code automation, and reporting.

Prism Ultimate

Prism Ultimate adds application discovery and monitoring, budgeting/chargeback and cost metering for resources, and a SQL Server monitoring content pack. Every Prism Central deployment includes a 90-day trial version of this license tier.

Add-Ons

See Add-On Licenses.

Cluster-based Licensing

Prism Central cluster-based licensing allows you to choose the level of data to collect from an individual Prism Element cluster managed by your Prism Central deployment. It also lets you choose the related features you can implement for a cluster depending on the applied Prism Central license tier. You can collect data even if metering types (capacity [cores] and nodes) are different for each node in a Prism Element cluster. See Prism Central Cluster-Based Licensing for more details.

AOS Capacity-Based Licensing

AOS capacity-based licensing is the Nutanix licensing model where you purchase and apply licenses based on cluster attributes. Cluster attributes include the number of raw CPU cores and raw total Flash drive capacity in tebibytes (TiBs). This licensing model helps ensure a consistent licensing experience across different platforms running Nutanix software.

Each license stores the currently licensed capacity (CPU cores/Flash TiBs). If the capacity of the cluster increases, the web console informs you that additional licensing is required.

Upgrade Licenses

An upgrade license enables you to upgrade your existing unexpired lower license tier to a higher license tier without having to purchase completely new stand-alone licenses. For example, you can upgrade your lower tier AOS Pro license to an Ultimate Upgrade license, which allows you to now activate or use the available Ultimate features.

For each upgrade license, you must have an existing unexpired lower tier license to activate the upgrade license. As with future licenses, you cannot apply an upgrade license to a cluster until the Start Date has passed.

View Upgrade Licenses at the Nutanix Support Portal

When you log on to the Nutanix Support portal and go to Licenses > License Inventory > Upgrade Licenses , the table shows all purchased Upgrade Licenses. See also Nutanix Support Portal Licenses Page.

A web page listing upgrade license details

Click a License Id link to see the properties of the upgrade license.

License ID . Upgrade license ID.
Upgraded From License . License ID of the existing unexpired lower tier license.
Applied qty / Available qty . Number of licenses that you have applied to clusters and the available number of licenses.
Product . Software product type such as Acropolis (AOS), Prism Central, and so on.
Tier . The upgraded license tier. Depending on your base lower tier, Pro or Ultimate.
Meter . How the license usage is metered. In this example, a capacity-based license (CBL) using vCPU cores as the metric.
Expires . Upgrade license expiration date. Your base license most likely has a different expiration date, expiring sooner than the upgrade license. The upgrade license typically extends your license term.

Nutanix Calm Licensing

For more information about how to enable Calm in Prism Central, see Enabling Calm in the Prism Central Guide and Calm Administration and Operations Guide.

The Nutanix Calm license for Prism Central enables you to manage the number of VMs that are provisioned or managed by Nutanix Calm. Calm licenses are required only for VMs managed by Calm, running in either the Nutanix Enterprise Cloud or public clouds.

The most current status information about your Calm licenses is available from the Prism Central web console. It is also available at the Nutanix Support Portal.

Once Calm is enabled, Nutanix provides a free trial period of 60 days to use Calm. It might take up to 30 minutes to show that Calm is enabled and your trial period is started.

Approximately 30 minutes after you enable Nutanix Calm, the Calm licensing card and licensing details show the trial expiration date. In Use status is displayed as Yes . See also License Warnings in the Web Console.

How The Nutanix Calm License VM Count is Calculated

The Nutanix Calm license VM count is a concurrent VM management limit and is linked to the application life cycle, from blueprint launch to application deletion. Consider the following:

You launch a Nutanix Marketplace blueprint as an application named Example that includes three VMs. These three VMs are counted against your Calm license (that is, three VMs under Calm management).
You later scale Example with two additional VMs. Now, five VMs are under Calm management.
You launch another blueprint as an application named Example2 with four new VMs. Total current number of VMs now under Calm management is nine (total from Example and Example2 ).
You delete Example . Total current number of VMs now under Calm management is four (from the existing active Example2 deployment).

Any VM you have created and are managing independently of Nutanix Calm is not part of the Calm license count. For example, you created a Windows guest OS VM through the Prism Element web console or with other tools (like a Cloudinit script). This VM is not part of a Calm blueprint.

However, if you import an existing VM into an existing Calm blueprint, that VM counts toward the Calm license. It counts until you delete the application deployment. If you stop the VM in this case and the application deployment is active, the VM is considered as under Calm management and part of the license count.

Endpoints Associated with a Runbook

For license usage, Calm also counts each endpoint that you associate to a runbook as one VM under Calm management. This license usage count type is effective as of the Nutanix Calm 3.1 release.

Add-On Licenses

Individual products known as add-ons can be added to your existing license feature set. For more information, see Nutanix Platform Software Options.

Before You License Your Cluster

Requirements and considerations for licensing. Consider the following before you attempt to manage your licenses.

Create a Cluster

Before attempting to install a license, ensure that you have created a cluster and logged into the Prism Element or Prism Central web console at least once. You must install a license after creating a cluster for which you purchased AOS Pro or AOS Ultimate licenses. If you are using Nutanix Cloud Clusters, you can reserve licenses for those clusters (see Reserve Licenses for Nutanix Cloud Clusters).

Before You Destroy a Cluster, Reclaim Licenses By Unlicensing Your Cluster

In general, before destroying a cluster with AOS licenses (Starter / Pro / Ultimate) for software-only and third-party hardware platforms, you must reclaim your licenses by unlicensing your cluster. Unlicensing a cluster returns your purchased licenses to your inventory.

You do not need to reclaim licenses in the following cases.

When you use the dark site license key method to apply a key to your cluster, there is no requirement to reclaim licenses. Each license key is associated with a unique cluster UUID, so there is nothing to reclaim.
You do not need to reclaim legacy-licensed life of device AOS Starter licenses for Nutanix and OEM AOS Appliance platforms. These licenses are embedded and are automatically applied whenever you create a cluster. You do need to reclaim AOS Pro and Ultimate licenses for these platforms.

Can I Mix License Tiers in a Cluster?

If a cluster includes nodes with different license tiers (for example, AOS Pro and AOS Ultimate), the cluster and each node in the cluster defaults to the feature set enabled by the lowest license tier. For example, if two nodes in the cluster have AOS Ultimate licenses and two nodes in the same cluster have AOS Pro licenses, all nodes effectively have AOS Pro licenses and access to that feature set only.

Attempts to access AOS Ultimate features in this case result in a license noncompliance warning in the web console.

License a Cluster and Add-On

As 1-click licensing is disabled by default, use these Update License procedures to license your cluster that is also connected to the Internet. These procedures also apply if a cluster is unlicensed (newly deployed or previously unlicensed by you).

Licensing a Cluster (Internet Connected)

Use this procedure to license your cluster. These procedures also apply if a cluster is unlicensed (newly deployed or previously unlicensed by you). After you complete this procedure, you can enable 1-click licensing.

Before you begin

For this procedure, keep two browser windows open:

One browser window for the Prism Element (PE) or Prism Central (PC) web console
One browser on an Internet-connected machine for the Nutanix Support Portal

Procedure

Log on to your PE or PC web console, click the gear icon, then select Licensing in the Settings panel.
Click Update License , then click Download to save a cluster summary file to your local machine.
The cluster summary file is saved to your browser download folder or any folder that you choose.

Figure. First Time Licensing Page Click to enlarge
To open the Nutanix Support Portal license page and upload the cluster summary file, click Licenses page , then click Manage Licenses at the portal.

  In most cases, select None of the Above . The list includes countries where certain technology license restrictions apply. If your cluster deployment is in one of those locations, select it.
3. Click Save .
  The Acropolis tile now shows the license level and other available license tiles. For example, your available add-ons like Nutanix Files are shown with a Add Licenses link, meaning you can apply that license now. Add-ons not associated with your account appear grayed out or unavailable. For example, you might not have the Data Encryption add-on feature.
[Optional] Before continuing, you can also license any add-ons as part of this step by clicking Add Licenses in the add-on tile.
Depending on the add-on, you simply license it with the same steps as the Acropolis work flow above (for example, Data Encryption). For add-ons that are based on capacity like Nutanix Files, you might have to specify the disk capacity to allocate to files. You can rebalance this add-on in the web console later if you need to make any changes.
If you choose not to license any add-ons at this time, you can license them later. See Licensing An Add-On (Internet Connected).
Click Next , review the Summary page, then click Confirm and Close .
Clicking Confirm automatically downloads the license summary file, which you need in the next step. Clicking Close shows the portal Licenses page with a summary of your purchased licenses, including how many you have used.

Enable 1-Click Licensing

This feature is not available to dark site clusters, which are not connected to the Internet. To enable 1-click licensing, you must create an API key and download an SSL key from your My Nutanix dashboard. 1-click licensing simplifies licensing by integrating the licensing work flow into a single interface in the web console. As this feature is disabled by default, you need to enable and configure it first.

Note: Your network must allow outbound traffic to portal.nutanix.com:443 to use this feature.

If your cluster is unlicensed, make sure you have licensed it first, then enable 1-click licensing. See Licensing a Cluster (Internet Connected).

1-click licensing simplifies licensing by integrating the licensing work flow into a single control plane in the Prism Element (PE) and Prism Central (PC) web consoles. Once you enable 1-click licensing, you can perform most licensing tasks from the web console Licensing settings panel without needing to explicitly log on to the Nutanix Support Portal.

1-click license management requires you to create an API key and download an SSL key from your My Nutanix dashboard to secure communications between the Nutanix Support Portal and the PE or PC web console.

With the API and SSL keys associated with your My Nutanix account, the web console can communicate with the Nutanix Support Portal to detect any changes or updates to your cluster license status.

The API key is initially bound to the user that creates the key on the Nutanix Support Portal. All subsequent licensing operations are done on behalf of the user who created the key and any operations written to an audit log include information identifying this user. That is, licensing task X was performed by user Y (assuming user Y created the key).
The API key is also bound to the Prism user that logs on to the web console and then registers the key. For example, if user admin registers the key, any licensing task performed by admin is performed on behalf of user Y (who created the key on the Support Portal). A Prism user (such as admin) must have access to the API key to use this feature. You can use Role Mapping and/or Lightweight Directory Access Protocol to manage key access or provide an audit trail if more than one admin user is going to manage licensing.

After enabling 1-click licensing, you can also disable it.

Enabling 1-Click Licensing

This feature is not available to dark site clusters, which are not connected to the Internet. To enable 1-click licensing, first create a Licensing API key and download an SSL public key. After you do this, register both through the Prism Element or Prism Central web console. You might need to turn off any pop-up blockers in your browser to display dialog boxes.

Before you begin

Ensure that you have an active My Nutanix account with valid credentials.
Make sure you have licensed your cluster first. See Licensing a Cluster (Internet Connected) or Licensing a Cluster (Dark Site).

Procedure

Create an API key and download the SSL key as described in Creating an API Key.
Make sure you select the Licensing scope when creating the API key. If you are currently logged on to the Nutanix Support Portal, you can access the API Key page by selecting API Keys from your profile. See also API Key Management.
When you create an API key, make sure you give it a unique name.
Register the keys through the Prism Element or Prism Central web console.
1. Log on to the web console, click the gear icon, then click Licensing .
2. Click Enable 1-Click Licensing .
3. Paste the API key in the API KEY field in the dialog box.
4. Add the SSL public key by clicking Choose File and browsing to the public key file that you downloaded when you created the key.
5. Click Save .
Figure. Enable 1-click licensing Click to enlarge

Messages display showing that 1-click licensing is enabled. You can also check related task messages on the Tasks page in the web console.
The Licensing page now shows two buttons: Disable 1-Click Licensing , which indicates 1-click licensing is enabled, and License With Portal , which lets you upgrade license tiers and add-ons by using the manual Nutanix Support Portal 3-step licensing work flow.

Below each license tile is the 1-Click Licensing options menu, where you can select more licensing actions: Rebalance , Extend , or Unlicense . See 1-Click Licensing Actions.

After enabling 1-click licensing, you can also disable it .

Disabling 1-Click Licensing

This feature is not available to dark site clusters, which are not connected to the Internet. Disables 1-click licensing through the web console. For security reasons, you cannot reuse your previously-created API key after disabling 1-click licensing.

About this task

You might need to disable the 1-click licensing connection associated with the API and public keys. If you disable the connection as described here, you can enable it again by obtaining a new API key as described in Creating an API Key.

Procedure

Log on to the web console, click the gear icon, then click Licensing .
Click Disable 1-Click Licensing .
Click Disable , then click Yes to confirm.
A status message and dialog box is displayed.
To close the dialog box, click Cancel .
The Licensing page now shows two buttons: Enable 1-Click Licensing , which indicates 1-click licensing is enabled, and License With Portal , which lets you upgrade license tiers and license add-ons by using the manual Nutanix Support Portal 3-step licensing work flow.

Manage Licenses with 1-Click Licensing

After you license your cluster, 1-click licensing helps simplify licensing by integrating the licensing work flow into a single interface in the web console. As this feature is disabled by default, enable and configure it first.

This feature is not available to dark site clusters, which are not connected to the Internet.

Once you configure this feature, you can perform most tasks from the Prism web console without needing to explicitly log on to the Nutanix Support Portal.

When you open Licensing from the Prism Element or Prism Central web console for a licensed cluster, each license tile includes a drop-down menu so you can manage your licenses without leaving the web console. 1-click licensing communicates with the Nutanix Support Portal to detect any changes or updates to your cluster license status.

If you want to change your license tier by upgrading or downgrading your license, use the procedures in Upgrading or Downgrading (Changing Your License Tier).

Before You Begin

Before you begin, make sure your cluster and any add-ons are licensed.

See Before You License Your Cluster, License a Cluster and Add-On, and Enable 1-Click Licensing.
Your network must allow outbound traffic to portal.nutanix.com:443 to use this feature.

1-Click Licensing Actions

On the Licensing page in the Prism Element or Prism Central web console for a licensed cluster, each license tile includes a drop-down menu so you can manage your licenses directly from the web console.

Rebalance

If you have made changes to your cluster, choose Rebalance to help ensure your available licenses (including licensed add-ons) are applied correctly. Use Rebalance if you:

Have added a node and have an available license in your account
Have removed one or more nodes from your cluster. Choose Rebalance to reclaim the now-unused license and return it to your license inventory.
Move nodes from one cluster to another.
Have reduced in capacity in your cluster (number of nodes, Flash storage capacity, number of licenses, and so on)

Extend

Choose Extend to extend the term of current expiring term-based licenses if you have purchased one or more extensions.

If your license has expired, you have to license the cluster as if it were unlicensed. See License a Cluster and Add-On.

Unlicense

Choose Unlicense to unlicense a cluster (including licensed add-ons) in one click. This action removes the licenses from a cluster and returns them to your license inventory. This action is sometimes referred to as reclaiming licenses.

Before destroying a cluster, you must unlicense your cluster to reclaim and return your licenses to your inventory.
You do not need to reclaim legacy-licensed life of device AOS Starter licenses for Nutanix and OEM AOS Appliance platforms. These licenses are embedded and are automatically applied whenever you create a cluster. You do need to reclaim AOS Pro and Ultimate licenses for these platforms.

License a Cluster and Add-On (Dark Site Legacy License Key)

Use this procedure to license your cluster if your cluster is not connected to the Internet (that is, a dark site). These procedures also apply if a cluster is unlicensed (newly deployed or previously unlicensed by you). This procedure requires you to collect only the PC or cluster UUID that you later enter at the Nutanix Support portal.

Note: To license a dark site cluster with a license key, first contact your account team (sales engineer) or Nutanix Support to enable this feature.

Use the procedure described in Licensing a Cluster (Dark Site Legacy License Key) if:

You have not purchased Nutanix cloud platform packages.
Your cluster is running a version of Nutanix Cluster Check (NCC) that supports license keys. See the NCC Release Notes version that introduces license key support
Your cluster is not licensed and also not connected to the Internet (that is, a dark site)
You are applying a license key that you generate from the Nutanix Support portal

If you purchased Nutanix cloud platform packages, see License a Cluster and Add-On (Dark Site Cloud Platform License Key).

Licensing a Cluster (Dark Site Legacy License Key)

Use this procedure to generate and apply a legacy license key to a cluster that is not connected to the Internet (that is, a dark site).

Before you begin

For this procedure, you must access:

The Prism Element (PE) or Prism Central (PC) dark-site web console
The Nutanix Support Portal on an Internet-connected machine

About this task

These steps apply to dark site clusters, where you are using the Nutanix Cluster Check utility script license_key_util to apply a legacy license key you obtain from the Nutanix Support portal. These procedures also apply if the dark site cluster is unlicensed (newly deployed or previously unlicensed by you) and you need to generate and apply a legacy license key.

Procedure

Log on to your dark-site PE or PC web console and get the cluster UUID.
1. Click the gear icon, then select Cluster Details in the Settings panel.
2. Copy the Cluster UUID.
On an Internet-connected machine, log on to the Nutanix Support portal and click Licenses > Summary > Manage Licenses .

1. Provide a unique Name for your cluster. The name cannot include spaces.
2. Enter the unique Cluster UUID .
3. Click the plus sign.
If you want to license more than one cluster and have the unique cluster UUID for each cluster, repeat these steps.
Click Next .
The Select Licenses page is displayed. Here, you can:
- Create a license tag to group your licenses or select an existing tag
- Select all licensing required for your cluster, like AOS, PC, and any add-ons.
If you have previously tagged your licenses as described in Creating and Adding a Tag to Your Licenses, select the tag name or All Licenses in the Choose License Tags drop-down menu.
The default tag is All Licenses . You can also leave this field blank.
Click Add Licenses in the Acropolis tile (for AOS clusters) or Prism tile (for PC clusters).
1. Select a License Level such as Pro or Ultimate from the drop-down menu.
2. For Cluster Deployment Location? , select your location or None of the Above .
  In most cases, select None of the Above . The list includes countries where certain technology license restrictions apply. If your cluster deployment is in one of those locations, select it.
3. Click Save .
  The Acropolis tile now shows the license level and other available license tiles. For example, your available add-ons like Nutanix Files are shown with a Add Licenses link, meaning you can add that license now. Add-ons not associated with your account appear grayed out or unavailable. For example, you might not have the Data Encryption add-on feature.
Before continuing, you can also license any add-ons as part of this step by clicking Add Licenses in the add-on tile.
Depending on the add-on, you simply license it with the same steps as the Acropolis work flow above (for example, Data Encryption). For add-ons that are based on capacity like Nutanix Files, you might have to specify the disk capacity to allocate to Files. You can rebalance this add-on in the web console later if you need to make any changes.
Click Next , review the Summary page, then click Generate License Keys .
The portal begins generating keys.
After the portal generates the keys, you can print the resulting page for a copy of the license keys or click Download as CSV to download a comma-separated file that lists each key and the associated cluster UUID.
For example, a key might look like this: ABCDE-FGH2K-L3OPQ-RS4UV-WX5ZA-BC7EF-GH9KL
Click Done .

Applying Licenses with the License Key

About this task

Apply the licenses with the license key to the dark site cluster with the license_key_util script. Apply one license key per cluster. The key is associated with the cluster UUID and is unique to that cluster, as described in this procedure.

When you apply the license key to the cluster, the license key enables the license tiers and add-ons that you select in this procedure. After you apply the key to your cluster, your license details show the AOS or Prism Central (PC) license tier, license class, purchased add-ons, and so on.

Procedure

Log on to the dark-site PE Controller VM or PC Controller VM with SSH as the Nutanix user.
To apply the licenses to the cluster, use the utility script license_key_util with the apply and cluster options. For example:
```
nutanix@cvm$ ~/ncc/bin/license_key_util apply key=license_key cluster=cluster_uuid
Licenses Applied:
AOS
Add-Ons:
Software_Encryption
File
```
Note: You must apply the PC license key first, and then you can apply the Prism Element (PE) license key. If you have multiple PE license keys, you must apply them one at a time.
Use the show option to display the licenses associated with the license key.
```
nutanix@cvm$ ~/ncc/bin/license_key_util show key=license_key cluster=cluster_uuid
Licenses Allowed:
AOS
Add-Ons:
Software_Encryption
File
```
You can also log on to the web console and display license details as described in Displaying License Features, Details, and Status.

Help is available from the command by typing ~/ncc/bin/license_key_util help

Manage Licenses for Dark Site Clusters (Legacy License Key)

Use these procedures if your cluster is not connected to the Internet (that is, your cluster is deployed at a dark site) and you plan to apply a legacy license key. To enter dark site cluster information at the Nutanix Support Portal and generate a legacy license key, use a web browser from a machine with an Internet connection.

To adhere to regulatory, security, or compliance policies at the customer site, dark-site AOS and Prism Central clusters are not connected to the Internet. 1-click licensing and License with Portal licensing actions are not available in this case.

Before You Begin

To license a dark site cluster with a license key, first contact your account team (sales engineer) or Nutanix Support to enable this feature.
Before attempting to install a license, ensure that you have created a cluster and logged into the Prism Element or Prism Central web console at least once.
You must install a license after creating a cluster for which you purchased AOS Pro or AOS Ultimate licenses. After creating the cluster, license your cluster, including any add-ons licensed. See Licensing a Cluster (Dark Site Legacy License Key) and Licensing An Add-On (Dark Site Legacy License Key).
A key point to remember is that each license key is associated with a unique cluster UUID. The generated key cannot be used with a different cluster (that is, with a different cluster UUID).

Dark Site Legacy License Key Considerations

Considerations and related actions or work flows that apply when you license your dark site Prism Element or Prism Central cluster with a license key. A key point to remember is that each license key is associated to a unique cluster UUID. The generated key cannot be used with a different cluster (that is, with a different cluster UUID).

When Do I Need to Generate a License Key?

You need to generate a license key at the Nutanix Support portal and apply it to your cluster for the following scenarios.

Licensing a cluster, including an unlicensed cluster (newly deployed or previously unlicensed by you).
Purchasing an add-on after previously licensing your cluster. For example, you applied a license key to your cluster that is running the AOS Pro tier. Six months later, you purchase the Nutanix Files add-on. You must license your cluster again with a new key to reflect the add-on.
Upgrading or downgrading your license tier.
Extending a license term. If you have purchased one or more license extensions, generate and apply a new key to extend the term of current expiring term-based licenses.

Do I Need to Rebalance a License Key After a Cluster Change?

No. Each license key is associated to a unique cluster UUID. If you have made changes to your cluster, you do not need to rebalance licenses across your cluster. A cluster rebalance or cluster change is defined as one or more of the following scenarios:

You add one or more nodes to your cluster.
You remove one or more nodes from your cluster.
You move one or more nodes from one cluster to another.
You reduce capacity in your cluster (number of nodes, Flash storage capacity, number of licenses, and so on).

Can I Reclaim Licenses and Return Them to My Inventory?

When you use the dark site license key method to apply a key to your cluster, there is no requirement to reclaim licenses. Each license key is associated with a unique cluster UUID, so there is nothing to reclaim.

Before I Destroy a Cluster, Do I Need to Reclaim the License Key?

No. Each license key is associated with a unique cluster UUID, so there is nothing to reclaim. When you create a new cluster, however, you do need to generate and apply a new license key.

I Previously Licensed My Clusters with a License Summary File. Can I Use License Keys Instead?

Yes. If your cluster is running the latest version of NCC and AOS or Prism Central versions compatible with this NCC version, you can switch to using a license key when any cluster attribute changes. That switch to a key includes clusters where you have upgraded NCC and AOS/Prism Central to versions that support license keys. Nutanix recommends the following if you want to use license keys:

See the NCC Release Notes version that introduces license key support.
Do not upgrade to using a license key unless your cluster attributes change.
If your cluster capacity or other cluster attribute changes (upgrade the license tier, extend the license term, or purchase additional add-ons), you can then license these changes by applying a license key.

Extending Your License Term (Dark Site Legacy License Key)

If you have purchased one or more license extensions to extend the term of current expiring term-based legacy licenses, use this procedure to update your cluster license.

Before you begin

For this procedure, you must access:

The Prism Element (PE) or Prism Central (PC) dark-site web console
The Nutanix Support Portal on an Internet-connected machine

About this task

Procedure

Log on to your dark-site PE or PC web console and get the cluster UUID.
1. Click the gear icon, then select Cluster Details in the Settings panel.
2. Copy the Cluster UUID.
On an Internet-connected machine, log on to the Nutanix Support portal and click Licenses > Summary > Manage Licenses .
From License Options , select Generate Legacy License Keys .
Depending on your cluster type, select Prism Element or Prism Central and do the following:
1. Provide a unique Name for your cluster. The name cannot include spaces.
2. Enter the unique Cluster UUID .
3. Click the plus sign.
If you want to license more than one cluster and have the unique cluster UUID for each cluster, repeat these steps.
Click Next .
If you have previously tagged your licenses, select the tag name or All Licenses in the Choose License Tags drop-down menu.
The default tag is All Licenses . You can also leave this field blank. To read about tags, see Creating and Adding a Tag to Your Licenses.
If your license has expired, do these steps. Otherwise, skip this step.
1. Click Add Licenses in the Acropolis tile (for AOS clusters) or Prism tile (for PC clusters).
2. Select a License Level such as Pro or Ultimate from the drop-down menu.
3. For Cluster Deployment Location? , select your location or None of the Above .
  In most cases, select None of the Above . The list includes countries where certain technology license restrictions apply. If your cluster deployment is in one of those locations, select it.
4. Click Save .
  The Acropolis tile now shows the license level and other available license tiles. For example, your available add-ons like Nutanix Files are shown with a Add Licenses link, meaning you can add that license now. Add-ons not associated with your account appear grayed out or unavailable. For example, you might not have the Data Encryption add-on feature.
5. [Optional] Before continuing, you can also license any add-ons as part of this step by clicking Add Licenses or Edit License in the add-on tile.
  Depending on the add-on, you simply license it with the same steps as the Acropolis work flow above (for example, Data Encryption). For add-ons that are based on capacity like Nutanix Files, you might have to specify the disk capacity to allocate to files. You can rebalance this add-on in the web console later if you need to make any changes.
Click Next , review the Summary page, then click Generate License Keys .
The portal begins generating keys.
After the portal generates the keys, you can print the resulting page for a copy of the license keys or click Download as CSV to download a comma-separated file with each key and associated cluster UUID.
For example, a key might look like this: ABCDE-FGH2K-L3OPQ-RS4UV-WX5ZA-BC7EF-GH9KL

Before You Begin

To license a dark site cluster with a license key, first contact your account team (sales engineer) or Nutanix Support to enable this feature.
Before attempting to install a license, ensure that you have created a cluster and logged into the Prism Central web console at least once.
You must install a license after creating a cluster for which you purchased NCI Pro or NCI Ultimate licenses. After creating the cluster, license your cluster, including any add-ons licensed. See Licensing a Cluster (Dark Site Cloud Platform License Key) and Licensing an Add-On (Dark Site Cloud Platform License Key).
A key point to remember is that each license key is associated with a unique cluster UUID. The generated key cannot be used with a different cluster (that is, with a different cluster UUID).

Dark Site Cloud Platform License Key Considerations

When Do I Need to Generate a License Key?

You must generate a license key at the Nutanix Support portal and apply it to your cluster for the following scenarios.

Licensing a cluster, including an unlicensed cluster (newly deployed or previously unlicensed by you).
Purchasing an add-on after previously licensing your cluster. For example, you applied a license key to your cluster that is running the NCI Pro tier. Six months later, you purchase the NDB add-on. You must license your cluster again with a new key to reflect the add-on.
Upgrading or downgrading your license tier.
Extending a license term. If you have purchased one or more license extensions, generate and apply a new key to extend the term of current expiring term-based licenses.

Do I Need to Rebalance a License Key After a Cluster Change?

You add one or more nodes to your cluster.
You remove one or more nodes from your cluster.
You move one or more nodes from one cluster to another.
You reduce capacity in your cluster (number of nodes, Flash storage capacity, number of licenses, and so on).

Can I Reclaim Licenses and Return Them to My Inventory?

Before I Destroy a Cluster, Do I Need to Reclaim the License Key?

No. Each license key is associated with a unique cluster UUID, so there is nothing to reclaim. When you create a new cluster, however, you do need to generate and apply a new license key.

I Previously Licensed My Clusters with a License Summary File. Can I Use License Keys Instead?

Yes. If your cluster is running the latest version of Nutanix Cluster Check (NCC) and AOS or Prism Central versions compatible with this NCC version, you can switch to using a license key when any cluster attribute changes. That switch to a key includes clusters where you have upgraded NCC and AOS/Prism Central to versions that support license keys. Nutanix recommends the following if you want to use license keys:

See the NCC Release Notes version that introduces license key support.
Do not upgrade to using a license key unless your cluster attributes change.
If your cluster capacity or other cluster attribute changes (upgrade the license tier, extend the license term, or purchase additional add-ons), you can then license these changes by applying a license key.

Reserve Licenses for Nutanix Cloud Clusters

Note: This feature applies to Nutanix Cloud Clusters only.

With a bring-your-own-license (BYOL) experience, you can leverage your existing on-prem licenses for Nutanix Cloud Clusters. You can reserve your licenses, partially or entirely, for Nutanix Cloud Clusters and specify the capacity allocation for cloud deployments. The licenses reserved for Nutanix Cloud Clusters are automatically applied to Cloud Clusters to cover their configuration and usage.

You can unreserve the licenses when you do not need them for Nutanix Cloud Clusters and add them back to the on-prem licenses pool. You can use the unreserved capacity for your on-prem clusters.

You can better use your licenses and control your expenses by tracking the reserved licenses consumption and making appropriate adjustments in the capacity usage. The reserved licenses are consumed first, and when no more reserved licenses are available, your chosen Pay As You Go or Cloud Commit payment plans are used.

Note:

You can reserve the licenses only if the products are metered and you are using Pay As You Go or Cloud Commit plans. The supported licenses are AOS PRO, AOS ULT, VDI ULT, and Files licenses.
It is recommended to unreserve the licenses and return them before your subscription is canceled or expired or when you terminate your cluster.
You can expand the license capacity up to the maximum unreserved capacity in the licenses pool and shrink the license capacity up to the currently used capacity.

Prism Central Cluster-Based Licensing

Cluster-based licensing allows you to choose the Prism Central (PC) features you can use and level of data to collect from a Prism Element (PE) cluster managed by your PC deployment.

With cluster-based licensing, you decide which PC license tier features to use to manage a specific cluster. For example, you might need features provided by a Prism Ultimate license to manage PE cluster A, while you only need Prism Pro features to manage PE cluster B. You can also designate a cluster (PE Cluster C) as unlicensed (no cluster-based license is applied). For example, you can leave a non-production or development cluster as unlicensed.

All nodes in a cluster must be licensed with a cluster-based license or unlicensed (that is, no cluster-based license is applied). For cluster-based licensing, all nodes in each cluster must be at the same cluster-based licensing tier. You cannot mix license tiers in the same cluster (for example, unlicensed and Prism Ultimate licensed nodes cannot reside in the same cluster).

Only Prism Starter features are available in an unlicensed cluster. If you try to access a Prism Pro or Prism Ultimate feature for an unlicensed cluster (for example, Capacity Runway), PC displays a Feature Disabled type message. Any unlicensed cluster data is filtered out from any reporting.

Cluster-based licensing also lets you select different metering types (capacity [cores] and nodes, depending on the cluster licensing) for each node in a PE cluster. Also, if your PC deployment includes Nutanix Calm or Flow, you can choose Calm Core or Flow Core licensing as the metering type.

See the Prism Central release notes or supplement where PC Cluster-based licensing is introduced. Also read Cluster-based Licensing Requirements and Limitations.

Prism Central is managing Prism Pro, Prism Ultimate, and unlicensed clusters

Cluster-based Licensing Requirements and Limitations

Cluster-based licensing is not available for dark site clusters or deployments where clusters are not connected to the Internet.
To use Prism Central (PC) cluster-based licensing, Prism Element (PE) AOS clusters registered with PC must be licensed with an AOS Starter, AOS Pro, or AOS Ultimate license.
If you have not implemented cluster-based licensing for your managed clusters, you have access to features provided by your existing PC license tier for all clusters registered to PC as usual.
When using PC cluster-based licensing, a PE cluster is considered unlicensed if no cluster-based license is applied. Only PC Starter features are available to manage a cluster without a cluster-based licensed applied.
If you have not implemented cluster-based licensing for your managed clusters when it is available in your PC version, the next time you update your license from PC (for example, applying a new license or consuming unused existing licenses), the Licensing page at the Nutanix Support portal will now present the cluster-based licensing work flow tasks. That is, you must now use cluster-based licensing for eligible registered clusters.

Manage Cluster-Based Licenses

The Prism Central (PC) web console Licensing page allows you to apply your cluster-based licenses with the Apply licenses button and by using 3-Step Licensing. 3-Step Licensing is a mostly manual licensing procedure. After the licenses are applied, manage them with the Update License button.

Before you begin, make sure AOS clusters registered with and managed by PC are licensed with AOS licenses.

In the PC web console, download a cluster summary file, then upload it to the Nutanix Support portal. Your network must allow outbound traffic to portal.nutanix.com:443.
Download a license file from the Nutanix Support portal.
In the PC web console, apply the license file.

The Licensing panel displays all license details for the cluster, like license tier, licensed add-ons, and expiration dates.

Nutanix Cloud Platform Package Licensing

Prism Central supports licensing for a set of cloud platform packages that deliver broad solutions to customers with simple and comprehensive bundles. The packages are:

Nutanix Cloud Infrastructure (NCI)
Nutanix Cloud Manager (NCM)
Nutanix Unified Storage (NUS)
Nutanix Database Service (NDB)
Nutanix End User Computing

You can add licenses or convert existing licenses to the new packages. For more information about the cloud platform packages, see Nutanix Cloud Platform Software Options.

Cloud platform licensing follows the same workflow as cluster-based licensing (see Prism Central Cluster-Based Licensing). This chapter provides supplemental information about licensing your clusters for the cloud platform packages.

Licensing Views

You can view licensing information from the Nutanix Support Portal for your entire account, Prism Central (PC) for all clusters registered to that PC instance, and Prism Element for that cluster. However, only the Support Portal and PC are used to apply or convert cloud platform licenses.

Support Portal Licensing View

The Licensing view on the Support Portal is extended to include cloud platform packages. Select Licenses from the collapse ("hamburger") menu to display the Licensing view. The Summary page includes widgets for any purchased licenses including cloud platform packages. The cloud platform package names also appear in the relevant fields in other licensing pages, for example the License Tier column in the Licensed Clusters page.

This picture shows the license summary page in the support portal.

Prism Central Licensing View

The Licensing view in PC is extended to include cloud platform packages. Select Licensing in the Settings panel to display the Licensing view. The View All Licenses tab includes sections for any applied licenses including cloud platform packages.

This picture shows the applied licenses summary page in Prism Central

Clicking View license details displays the details page, which also now includes applied cloud platform package license information.

This picture shows the applied licenses details page in Prism Central

The View all clusters tab and cluster license details pages are also extended to include cloud platform packages.

Applying Cloud Platform Licenses

Use this procedure to apply cloud platform licenses to your cluster.

Before you begin

Make sure that the cluster is connected to the Internet (no dark sites).
You might need to turn off any pop-up blockers in your browser to display dialog boxes.
Applying cloud platform licenses, excluding NUS, requires that the cluster is running the minimum versions of the following software:
- AOS 6.0.1.7
- Nutanix Cluster Check (NCC) 4.3.0
- pc.2021.9
Applying NUS licenses requires that the cluster is running the minimum versions of the following software:
- AOS 6.1.1
- NCC 4.5.0
- pc.2022.4

Conversion Requirements and Mapping

This topic contains requirements and limitations for you to consider before you convert your existing licenses to the new cloud platform packages. This topic also provides a conversion table of old (current) to new (cloud platform) licenses.

Review the following requirements and limitations before you convert licenses to the new cloud platform packages.

Requirements
- The cluster is running the minimum versions of AOS 6.0.1.7, Nutanix Cluster Check (NCC) 4.3.0, and pc.2021.9. For NUS, the cluster is running the minimum versions of AOS 6.1.1, NCC 4.5.0, and pc.2022.4.
- The cluster is fully licensed before conversion or has enough available licenses to fully convert the cluster (combination of old and new licenses).
- The expiration date must be the same if two licenses are being merged into one, for example AOS + Flow or Prism + Calm.
- ATR-related objects are not populated immediately after conversion. Actions to populate ATR-related objects are triggered after the cool off period (1 week) after conversion.
- All existing Prism licenses in a Prism Central instance should be converted to NCM.
- Flow, Encryption, and Object licenses must be applied. Unapplied licenses will not be converted.
Limitations
- Cloud platform licensing is not available for dark sites.
- The following licenses may not be converted: POC (Proof of Concept), LOD (Life of Device), EPA (Enterprise Purchase Agreement), NTE (Not To Exceed), Upgrade Licenses, SWO (software only) perpetual licenses.
- Prism Pro, Prism Ultimate, and Calm licenses may not be mixed with cloud platform licenses in a single Prism Central.
- Conversion is not allowed if an upgrade quote is in flight, the license is due for renewal in the next 90 days, or a renewal opportunity is in the advanced stage.
- RBAC-based users are not allowed to perform conversions.
- Partial conversions are not allowed for Files licenses. All Files licenses in Prism Central are converted.

Use Tags to Organize Your Licenses

On the Licenses > License Inventory page on the Nutanix Support portal, you can label your licenses with a tag to conveniently group them.

Tags help provide more granularity and ease of use to your license management.

For example, you can apply a tag to licenses to group them according to:

A common expiration date
Use case (clusters used by remote offices)
Assigned organization (clusters used by an engineering department)

When you tag one or more licenses, you can then:

Sort them by tag name on the support portal
Perform license actions (on the portal) on clusters grouped by tag (especially when selecting licenses manually)

Creating and Adding a Tag to Your Licenses

Label your licenses with a tag to conveniently group them. You can add multiple tags to a single license.

Procedure

Log on to the Nutanix Support Portal, then click Licenses > License Inventory .
The portal displays a sortable table listing your purchased licenses. You can sort the table by clicking any table heading (License ID, Tier, License Class, and so on).
To create a new tag:
1. Click Actions > Create a Tag , then enter a tag name in the New Tag field.
2. Click Create .
To apply one or more existing tags:
1. Select the licenses that you want to tag, then click Actions > Add or Remove Tag .
2. Click the field and then select one or more existing tags from the drop-down list.
3. Click Apply .
The Support Portal web page refreshes and displays your tagged licenses.

Renaming a Tag or Removing a Tag from a License

About this task

This procedure describes how to rename a tag or remove a tag from a license (that is, how to untag it).

Note: To delete an existing tag, which also removes the tag from any licenses where it is applied, see Deleting a Tag.

Procedure

Log on to the Nutanix Support Portal, then click Licenses > License Inventory .
The portal displays a sortable table listing your purchased licenses. You can sort the table by clicking any table heading (License ID, Tier, License Class, and so on).

If you know the name of a tag, you can type the name and then select it from the list.
Click Apply .
The existing tag is deleted, which also removes the tag from any licenses where it is applied. The portal removes the tag from the list.

License Warnings in the Web Console

Most license warnings in the web console are related to license violations or licenses that are about to expire or expired. In most cases, the resolution is to extend or purchase licenses.

AOS and Prism Starter licenses never expire for Nutanix NX and third-party OEM hardware appliances. Go to Licensing in the web console to check your Starter license expiration status.
AOS, Prism Pro, and Ultimate licenses have an expiration date. The web console alerts you both before and after a license expires.
If you attempt to use features not available in the license level for the cluster, a warning is issued. Upgrade your license level if you require continued access to Pro or Ultimate features.
If a cluster includes nodes with different license levels, the cluster and each node in the cluster defaults to the minimum feature set enabled by the lowest license level. For example, if two nodes in the cluster have AOS Pro licenses and two nodes in the same cluster have AOS Ultimate licenses, all nodes will effectively have AOS Pro licenses and access to that feature set only. Attempts to access AOS Ultimate features in this case result in a Warning in the web console.
If you are using a trial license, the warning shows the expiration date and number of days left in the trial period. Typically, the trial period is 60–90 days. The license name will also display as a Trial license level.
During upgrade of AOS, the Prism web console might incorrectly display a license violation alert. After you complete the upgrade, the alert is not displayed.

Nutanix Calm License Warnings in the Web Console

Most license warnings in the web console are related to license violations or licenses that are about to expire or have expired. In most cases, the resolution is to extend or purchase licenses.

Nutanix Calm licenses have an expiration date. The web console alerts you both before and after a license expires.
An alert is generated providing the number of license packs required for compliance. For example, The cluster needs 1 additional license pack. Please expand Calm capacity with 1 pack.
If the license pack is already expired, an alert is generated.

Note:

Any powered off VMs are also counted for license calculation.
If a VM is deleted manually from a cloud provider without deleting the app from Calm, it will be counted for license calculation.
After applying a new license, you can wait for the next scheduled Nutanix Cluster Checks to run and only after that the alerts are auto-resolved.

Disabling a Trial License

How to disable the Prism Pro or Prism Ultimate tier (and remove the violating license message that appears in Prism Central if the Prism Pro features are enabled without a valid license).

Procedure

Log on to Prism Central (PC), click the gear icon, and select Licensing .
In the Licensing page, click View & Manage Features .
For example, click Disable Ultimate Trial .

A message box appears stating that the operation is reversible. Click the Disable Ultimate Trial button. This immediately logs you out of PC and returns you to the logon page. When you log back on, the features are disabled.

Disabling An Existing Trial License After Upgrading

Follow these steps to disable the trial license if your current license tier is Prism Pro Trial and after upgrading, a Prism Ultimate tier trial is available. Enable and then disable the Ultimate trial to remove the trial from the cluster.

Procedure

Log on to PC, click the gear icon, and select Licensing .
In the Licensing page, click View & Manage Features .
Click Enable Ultimate Trial .
This immediately logs you out of PC and returns you to the logon page. When you log back on, the features are enabled.
In the Licensing page, click View & Manage Features .
Click Disable Ultimate Trial .

A message box appears stating that the operation is reversible. Click the Disable Ultimate Trial button. This immediately logs you out of PC and returns you to the logon page. When you log back on, the features are disabled.

API Key Management

After you log on to My Nutanix and depending on your role, the API Key Management tile enables you to create and manage API keys. Use these keys to establish secure communications with Nutanix software and services. Typical user roles able to access this tile include Account Administrators for Cloud Services and existing Support Portal users.

An API key is a unique token that you can use to authenticate API requests associated with your Nutanix software or service. You can create multiple API keys for a single product or service. However, you can use an API key only once to register with that software or service.

It is a randomly generated unique UUID4 hash and can be 36–50 characters long. When you create the key, you choose a service (such as Licensing) and the key is mapped directly to that service. You can use it for the chosen service only. For example, you cannot use a Support Case key with Prism Central (PC).

You can use the API key for secure communication in many scenarios, including but not limited to the following.

Licensing. 1-click licensing for Nutanix software
Create Support Case. Generating support cases associated with your account
Prism Ops. API IAMV1 token generation and authorization

API Key Scope

Scope is the service group, feature, or specific function of a service group and is defined as part of a unique key value pair (scope name paired with the unique scope category). For example, with Prism Ops as the scope, the generated key enables you to authenticate when using the PC or Prism Element (PE) APIs.

The API Key is restricted for use depending on the scope you choose. For example, a key created with a scope of Licensing allows you to enable 1-click licensing through the PE or PC web console.

Creating an API Key

The API Key Management tile is available depending on your role. Typical user roles able to access the tile include Account Administrators for Cloud Services and existing Support Portal users.

Before you begin

Ensure that you have an active My Nutanix account with valid credentials.
You can create one or more API keys associated with a scope (that is, service such as Licensing). However, you can use only a specific key once when you register it with the service (for example, when enabling 1-click licensing in the web console).

Procedure

Log on to your My Nutanix or cloud account at https://my.nutanix.com.
In the My Nutanix dashboard, find the API Key Management tile and click Launch .
If you have previously created keys, this page displays a list of keys and the +Create API Keys button.
To begin, click +Create API Keys .
The Create API Key window is displayed.
Do these steps.
1. Name. Enter a unique name for your API key to help you identify the key.
2. Scope. Select a scope category from the Scope drop-down list.
  Scope is the service group, feature, or specific function of a service group and is defined as part of a unique key value pair (scope name paired with the unique scope category). For example, with Prism Ops as the scope, the generated key enables you to authenticate when using the Prism Central or Prism Element APIs.
Click Create .
The Created API Key window is displayed. Do not click Close . The window always shows an API Key field. Depending on the scope you chose, it might also show a Key ID field and Download Optional SSL Key button.
Caution: You cannot recover the generated API key and key ID after you close this window. Click the icon to copy the API key and key ID and store it securely. If you forget or lose the API Key, generate a new API Key.

Figure. Example API Key and Key ID for Prism Ops Scope Click to enlarge

To optionally generate an SSL key, click Download optional SSL Key to save it for use when you register the API Key.
Download optional SSL Key appears if you choose Licensing and Create Support Case scope categories. To enable 1-click licensing, the SSL is required. Download it if this is your use case.
Click Close .
The API Key Management page shows the key that you created (by name and scope) and any other keys you have created.

Viewing API Key Details

The API Key Management tile is available depending on your role. Typical user roles able to access the tile include Account Administrators for Cloud Services and existing Support Portal users.

Procedure

Log on to your My Nutanix or cloud account at https://my.nutanix.com.
In the My Nutanix dashboard, find the API Key Management tile and click Launch .
If you have previously created keys, this page displays a list of keys and the +Create API Keys button.
To view information about a specific API key, click Details to the right of the API key.
A window is displayed, showing audit information about the key.
To optionally generate an SSL key, click Download optional SSL Key to save it for use when you register the API Key.

Mine™ with Veeam Guide

Mine 2.0.1

Last updated: 2022-09-11

Release Notes

Release 2.0.1

Note the following that are new for release 2.0. The release 1.0 notes also apply to 2.0 (except for the required AOS version).

A Mine™ cluster requires a current LTS version of AOS (5.15 or 5.20). AOS STS versions are not recommended.
Foundation for Mine™ with Veeam automatically installs Veeam Backup & Replication v10. (Release 1.0 installed Veeam Backup & Replication v9.5.)
The "Physical Cluster Usage" and "Storage Throughput" widgets in the Mine™ dashboard now display usage data when you hover the mouse over any point on the time line.
If you see an "Unable to load Mine configuration settings …" error when viewing the Mine™ dashboard in Prism, the problem is likely DNS related. To circumvent the issue, access Prism using an IP address instead of a host name.
The Mine™ console now includes an option to upgrade the Mine™ version. However, this is a feature of 2.0, so it cannot be used to upgrade from 1.0 to 2.0 without some intervening manual steps. To upgrade from 1.0 to 2.0, do the following:
1. Upgrade Veeam Backup & Replication server from 9.5 to 10 patch 2 (see Upgrading from Veeam Availability for Nutanix AHV 1.0 ).
2. Log on to Prism, go to the VMs dashboard, select the Mine™ foundation VM ("Foundation for Mine with Veeam" VM), and click the Launch Console button (below the table) to open the console. Enter your login credentials when prompted.
3. Using a text editor, add the following lines to the end of the file /etc/apt/sources.list :
```
deb [arch=amd64] https://repository.veeam.com/mine/1/public/updater stable main
deb [arch=amd64] https://repository.veeam.com/mine/1/public/mine stable main
```
4. Enter the following curl command (as root) to add a repository key:
```
veeam@minevm$ sudo su
root@minevm$ curl http://repository.veeam.com/keys/veeam.gpg | apt-key add
root@minevm$ exit
```
5. Using a text editor, update the /etc/apt/apt.conf.d/50unattended-upgrades file as follows:
  1. Uncomment the following two lines:
```
${distro_id}ESM:${distro_codename}";
${distro_codename}-security";
```
  2. In the same section, add the following line:
```
"Foundation for Mine With Veeam updater:stable";
```
  The following is an example of the updated section:
```
// Automatically upgrade packages from these (orign:archive) pairs
Unattended-Upgrade::Allowed-Origins {
        "${distro_id}:${distro_codename}";
        "${distro_id}:${distro_codename}-security";
        // Extended Security Maintenance; doesn't necessarily exist for
        // every release and this system may not have it installed, but if
        // avaliable, the policy for updates is such that unattended-upgrades
        // should also install from here by default.
        "${distro_id}ESM:${distro_codename}";
//      "${distro_id}:${distro_codename}-updates";
//      "${distro_id}:${distro_codename}-proposed";
//      "${distro_id}:${distro_codename}-backports";
        "Foundation for Mine With Veeam updater:stable";
```
6. Enter the following two commands to update the installer:
```
veeam@minevm$ sudo apt-get update;
veeam@minevm$ sudo apt-get install nirvana-mine nirvana-appliancemanager;
```
7. You should now be able to use the update feature in the Mine™ console (see Upgrading Mine Using Mine Console).
After upgrading from Mine™ 1.0 to 2.0, you might see a "Fast clone is disabled, to enable it, turn on Align data block on SOBR extents" when you open the Mine™ dashboard in Prism. Veeam Backup & Replication v10 supports the fast clone operation for XFS, and it is enabled by default in Mine™ 2.0. However, when upgrading form Mine™ 1.0, you need to enable the fast clone feature manually as described here.
A default container (named default-XXX) is created as part of creating a Nutanix cluster. Do not delete or rename the default container before deploying a Mine™ cluster because Mine™ requires this container.
The Mine™ dashboard does not appear in Prism if you access the cluster (Prism Element) from Prism Central. It appears in Prism only when you log on to the cluster directly.

Note the following:

This guide provides instructions for installing and deploying a Mine™ cluster. However, only designated Nutanix and Veeam sales or support engineers, or VAR engineers, should perform the installation. (The FoundationMine image ISO to create the Foundation for Mine™ with Veeam VM is provided to the designated Nutanix, Veeam, or VAR engineers.)
A Mine™ cluster requires AOS version 5.11.2.1 or later.
After installation, DO NOT delete, reconfigure, or power off the Foundation for Mine™ with Veeam VM or any of the six deployed VMs ( Veeam-Win-Node1 , Veeam-Win-Node2 , Veeam-Win-Node3 , Veeam-Lin-Node1 , Veeam-Lin-Node2 , Veeam-Lin-Node3 ).
Do not enable AOS fingerprinting/deduplication on any of the containers on the Nutanix Mine™ with Veeam deployment.
Instead of using the default admin account to administer a Mine™ cluster, it is recommend that you create a separate administrator account for Mine™ to circumvent two potential issues that could occur when using the default admin account (warnings may appear about external authentication and robot accounts are not obliged under security policies to have password change after every n months).
If the custom Mine™ dashboard does not appear in Prism (see Monitoring the Cluster), refresh (clear) the cache on your browser and redisplay Prism. The missing Mine™ dashboard should now appear.
When uploading a Windows image to install (see step 7 in Deploying a Mine™ Cluster), be sure it is Windows Server 2019 Standard Edition as that is the only supported version currently.

Overview

Video: Mine™ Overview This video https://youtu.be/9NQRreAF1I0 is from Nutanix, Inc. on YouTube.

Nutanix Mine™ is the product name for joint solutions between Nutanix and select data protection software vendors. Nutanix Mine™ is a dedicated backup solution, where only backup component VMs run on the Mine™ cluster and the cluster storage is used to store backup workloads.

This version of Mine™ is a fully integrated data protection appliance that combines the Nutanix AOS software with the Veeam Backup & Replication solution. Mine™ can provide data protection for any applications running in a Nutanix cluster or for any virtualized workload running in your data center. Mine™ includes the following features:

Enterprise-grade data protection to any workload in your data center
Integrated installation and configuration experience
Integrated management experience
Seamless scale-out, self-healing, and break-fix functionality

Note: The Mine™ cluster is not a disaster recovery solution, thus restoring primary or production workloads to the Mine™ cluster is not supported currently. Attempting to run restored VMs on a Mine™ cluster disrupts the HA functionality of the cluster. In case of a node failure, the system might not be able to recover all the Veeam services automatically.

The Mine™ appliance comes in three initial sizes, "extra small" and "small" versions that include one preconfigured NX-1465 block and a "medium" version that includes two preconfigured NX-8235 blocks. You can add additional NX-8235 blocks (but not NX-1465 blocks) to scale out the cluster for more capacity.

Installation

Installing and configuring your Mine™ with Veeam solution requires the following steps:

Install the Mine™ appliance (see Installing a Mine™ Appliance).
Deploy a Mine™ cluster (see Deploying a Mine™ Cluster).
Configure the Veeam backup and replication solution (see Configuring Veeam).

Installing a Mine™ Appliance

About this task

To install a Mine appliance at your site, do the following:

Note: The Mine™ cluster itself only supports AHV as a hypervisor. While Mine with Veeam can backup workloads from other hypervisors or physical infrastructure, the Mine cluster itself is deployed with AHV as the hypervisor.

Procedure

Unpack the block and nodes (see the Getting Started Guide for steps 1-4).
Mount the block in a rack.
Connect each node to the network.
Create a cluster of the Mine nodes with AHV as the hypervisor.

It is recommended to use the AHV version bundled with the supported AOS (LTS) package. The recommended memory size for the Controller VMs is 32 GB.
Download the NutanixFoundationForMineWithVeeam- <ver#> .vmdk file from the Nutanix Mine™ download page in the Nutanix support portal.
After the cluster is up and running, import the Mine foundation VM image (VMDK file) that you downloaded in the previous step (see the "Configuring Images" section in the Prism Web Console Guide ).

Note: See the "Logging Into the Web Console" section in the Prism Web Console Guide if you need help when logging on to Prism for the first time. In addition, an iSCSI data services IP address should be specified for the cluster before deploying Mine (see the "Modifying Cluster Details" section).
Create a "Foundation for Mine with Veeam" VM from the imported image, connect it to the production network, and start it (see "VM Management" in the Prism Web Console Guide ).

Allocate 4 vCPUs and 4 GB of memory to this VM. Select Clone from Image Service as the operation and FoundationMine as the image when adding the disk.

Note: The VM is named "Foundation for Mine with Veeam" throughout this document, but you can name the VM anything you want when you create it.

Deploying a Mine™ Cluster

Before you begin

Make sure the Mine™ appliance is up and running before attempting this procedure.

About this task

Video: Mine™ Deployment Example This video https://youtu.be/e13I-VXVaoo is from Nutanix, Inc. on YouTube.

To deploy a new Mine™ cluster, do the following:

Procedure

Do one of the following to access the Mine™ console:
- If DHCP is configured for the production network, open a web browser and enter http:// foundation_for_mine_with_veeam_vm_ip_addr . This defaults to port 8743, which is the port for the Mine™ web console.
  Note: The supported browsers are the current version and two major versions back of Firefox, Chrome, and Safari, plus Internet Explorer version 11.
- If DHCP is not configured, log on to Prism, go to the VMs dashboard, select the Foundation for Mine with Veeam VM, and click the Launch Console button (below the table) to open the console. In the console do the following to manually set the IP address:
  1. Log on to the VM (both user name and password are "veeam").
  2. Open the /etc/network/interfaces file for editing. For example, to use the nano editor, enter
```
sudo nano /etc/network/interfaces
```
  3. Find the following lines in the file:
```
auto eth0
iface eth0 inet dhcp
```
  4. Replace those lines with the following lines:
```
auto eth0
iface eth0 inet static
address yourIpAddress
netmask yourSubnetMask
gateway yourAddressAddress
```
  5. Save the file and then run the following command:
```
sudo service networking restart
```
    If you require an Active Directory join, you also need to specify a DNS server with a proper Active Directory record.
Enter your credentials (user name and password) in the login page.

What to do next

Deploying a Mine™ cluster creates a volume group, and both the volume group and Foundation for Mine™ with Veeam VM are added automatically to a protection domain. A schedule is set up to take daily snapshots of the protection domain. Tune the schedule (if needed) per your company security policy.

It is recommended that you enable erasure coding (disabled by default). Erasure coding can provide significant storage savings for a Mine™ cluster. See the "Erasure Coding" and "Modifying a Storage Container" sections in the Prism Web Console Guide for more information.

Configuring Veeam

About this task

To configure the Veeam backup and replication solution for a Mine™ cluster, do the following:

Procedure

Log on to Prism.
Go to the Mine with Veeam dashboard (see Monitoring the Cluster) and click the Launch Console link in the Cluster widget.

This opens a Veeam console window at the login screen. Enter the Windows administrator credentials you supplied when deploying the cluster (see Deploying a Mine™ Cluster).

You can also launch the Veeam console by going to the VMs dashboard, selecting the Veeam-Win-Node1 VM, and then clicking the Launch Console button below the table.
Click the Veeam Backup icon on the desktop to open that application.

Figure. Veeam VM Desktop Click to enlarge
Configure the Veeam backup and replication solution as desired. See the Veeam Backup & Replication for Nutanix Mine™ (Getting Started Guide) for instructions.
Depending on which systems you want to back up with Nutanix Mine™, also check the relevant guides from the following list to configure Veeam Backup & Replication for your environment:
- AHV: Veeam Backup for Nutanix AHV User Guide
- ESXi: Veeam Backup & Replication User Guide for VMware vSphere
- Hyper-V: Veeam Backup & Replication User Guide for Microsoft Hyper-V
- physical server: Veeam Agent for Microsoft Windows User Guide or Veeam Agent for Linux User Guide

Administration

After deploying a Mine™ cluster, you can monitor activity and perform administrative tasks as needed.

Note: Depending on the task, administration is through either the Mine™ or Prism web console. To access the desired console, open a web browser and enter one of the following addresses:

Mine console: http:// foundation_for_mine_with_veeam_vm_ip_addr . This defaults to port 8743, which is the port for the Mine™ web console.
Prism console: http:// cvm_ip_addr where cvm_ip_addr is the IP address for one of the Controller VMs in the cluster or the virtual IP address if one was created. This defaults to port 9440, which is the port for the Prism web console.

You can monitor cluster usage and health through Prism (see Monitoring the Cluster).
You can expand the cluster storage capacity by adding Mine™ blocks (see Expanding the Cluster).
You can upgrade the Mine™ version for the cluster (see Upgrading Mine Using Mine Console).
You can upgrade AOS in a Mine™ cluster, but it requires a few extra steps (see Upgrading AOS).
You can update your Veeam, Mine™, or Prism user credentials (see Updating User Credentials).
If you encounter a problem with the cluster, you can download a support bundle that contains various logs and other relevant data (see Downloading a Support Bundle).
If the installation fails or you want to start over for any reason, you can reset the cluster back to the original state (see Resetting the Cluster).
If you want to perform cluster actions that require the backup processes be suspended such as when expanding (or contracting) the cluster or upgrading AOS, you can enable a maintenance mode (see Maintenance Mode).

Monitoring the Cluster

You can monitor the Mine™ cluster health and activity through Prism. The Prism Web Console Guide describes how to use Prism. (To determine the AOS version your Mine™ cluster is running, go to the About Nutanix option under the user_name drop-down list in the Prism main menu.)

Mine™ with Veeam Dashboard

The Prism web console includes a custom Mine with Veeam dashboard specific to a Mine™ cluster, which appears by default when you first log on to Prism. To view this custom dashboard at any time, select Mine with Veeam from the pull-down list on the far left of the main menu.

The custom dashboard displays the following eight information tiles (widgets):

Cluster . The cluster tile provides quick visual indicators for the following components: cluster health (overall), Veeam implementation, Mine™ components, and storage capacity (available). Green indicates a healthy component, yellow indicates a warning condition, and red indicates a critical condition.
- Click the Launch Console link to open a Veeam console.
- Click the Mine Platform link to open the Mine™ console.
Protection . The protection tile displays a summary of the VMs and hosts protected currently.
Job Status . The job status tile displays a summary of the running, disabled, and idle jobs in the cluster currently.
Physical Cluster Usage . The physical cluster usage tile displays a timeline graph of storage usage in the cluster.
Storage Throughput . The storage throughput tile displays a timeline graph of storage throughput in the cluster.
Capacity Usage . The capacity usage tile summaries the current storage usage and available capacity (see Monitoring Storage).
Nutanix Alerts . The Nutanix alerts tile displays a list of the current Nutanix-specific alerts.
Veeam Backup & Replication Alerts and Events . The Veeam alerts and events tile displays a list of the current Veeam-specific alerts and events.

Other Dashboards

The Prism web console includes other dashboards to monitor specific elements of your cluster.

Note: All sections and chapters cited below are located in the Prism Web Console Guide.

You can monitor the Mine™ VMs through the VMs dashboard. This dashboard provides a summary table of the VMs and allows you to view details about each VM. See the "VMs Dashboard" section for more information.
Figure. Prism VMs Dashboard (table view) Click to enlarge
Mine™ creates automatically a storage container and volume group that you can monitor through the Storage dashboard. This dashboard provides summary and detailed information about storage containers, volume groups, and storage pools. See the "Storage Dashboard" section for more information.
Figure. Prism Storage Container Tab Click to enlarge

Figure. Prism Volume Group Tab Click to enlarge
You can monitor the progress and outcomes for Mine-related tasks through the Tasks dashboard. See the "Task Status" chapter for more information.
You can review the Mine-related alerts and events through the Alerts dashboard. See the "Alert and Event Monitoring" chapter for more information.

Monitoring Storage

When a Mine™ cluster is full, the cluster may become unavailable, and you will not be able to continue backup operations. To prevent such a situation, Mine™ includes a special monitoring feature (sometimes referred to as a "watchdog") that dynamically monitors storage usage and takes action as necessary to avoid reaching a storage full condition. If available storage space in the cluster falls below the minimum amount, the monitor automatically stops and disables Veeam Backup & Replication jobs. The monitor is regulated by three thresholds:

"Low on space" threshold ( restart_jobs_threshold_percent parameter). When available storage space on a cluster reaches the specified threshold, Veeam Backup & Replication starts to upload the VM backup files to Capacity Tier. For details, see the "Capacity Tier" section of the Veeam Backup & Replication User Guide .
"Job processing is impacted" threshold ( cancel_jobs_threshold_percent parameter). When available storage space on a cluster reaches the specified threshold, Mine™ disables all Veeam Backup & Replication jobs. Already started jobs continue the session, but subsequently scheduled runs are suspended until more storage space become available.
"Immediate stop" threshold ( stop_issuing_jobs_threshold_percent parameter). When available storage space on a cluster reaches the specified threshold, Mine™ immediately stops all running jobs.

The monitor automatically calculates and defines the threshold values according to your environment resources. (If you want to change default threshold values, contact technical support.) In addition, the monitor regulates the location of VMs. If Veeam repository extends and backup proxies are deployed on different AHV nodes, the monitor transfers them to one node.

By default, Mine™ reserves enough storage space for node rebuild should one of the nodes fail. If you want to add new VMs on the cluster or change the default monitor threshold values, consider leaving enough space for the rebuild of the node.

Note: When you free up space on a Veeam backup repository, it may take up to six hours until you see the change reflected in the Mine™ dashboard.

Expanding the Cluster

About this task

To increase the storage capacity of your Mine™ cluster, you can add an expansion block (see Overview). To add the nodes in an expansion block to the cluster, do the following:

Procedure

Log on to the Mine™ console and enable maintenance mode (see Enabling Maintenance Mode).

Maintenance Mode

Mine™ provides a maintenance mode that stops and disables all running backup jobs which are targeted at the scale-out backup repository. Maintenance mode allows you to reconfigure cluster settings, expand the cluster, and perform additional tasks that might otherwise disrupt backup operations. When cluster maintenance is complete, you can disable maintenance mode, which resumes the scheduling of backup jobs. (However, backup jobs that were stopped during the maintenance window are not restarted.)

Enabling Maintenance Mode

About this task

To enable maintenance mode, do the following:

Procedure

Log on to the Mine™ console.
Select Maintenance from the main menu screen.

Mine™ with HYCU Guide

Mine 3.0

Product Release Date: 2021-07-06

Last updated: 2022-06-27

Overview of Mine™

Nutanix Mine™ is the product name for joint solutions between Nutanix and select data protection software vendors. Nutanix Mine is a dedicated backup solution, where only backup component VMs run on the Mine cluster and the cluster storage is used to store backup workloads.

This version of Mine is a fully integrated data protection appliance that combines the Nutanix AOS and Objects software with the HYCU Data Protection for Enterprise Clouds solution. Mine can provide data protection for applications running in a Nutanix cluster and also for other virtualized workloads running in your datacenter.

Mine includes the following features:

Enterprise-grade data protection to any workload in your datacenter.
Integrated installation and configuration experience.
Integrated management experience.
Seamless scale-out, self-healing, and break-fix functionality.

Note: The Mine cluster is not a disaster recovery solution, thus restoring primary or production workloads to the Mine cluster is not supported currently. Attempting to run restored VMs on a Mine cluster disrupts the HA functionality of the cluster. If a node fails, the system might not be able to recover all the HYCU services automatically.

Overview of Mine™ with HYCU

Nutanix Mine with HYCU is a high-performance backup and recovery solution for the Nutanix hyperconverged platform.

HYCU is fully integrated with Nutanix, making data protection easy to deploy and simple to use. Nutanix Mine with HYCU allows you to manage production (primary) and backup (secondary) infrastructures using Nutanix Prism. You can order Nutanix Mine with HYCU as a single SKU that enables you to deploy and to scale up a turnkey backup solution.

For information on performing various tasks, such as deploying and upgrading HYCU to a Nutanix cluster, registering HYCU with Nutanix Prism, and accessing HYCU from the Nutanix Prism web console for Nutanix Mine with HYCU, see HYCU User Guide.

Note: You can deploy Mine only from the HYCU backup controller user interface. For information on deploying the HYCU backup controller, see Deploying a temporary HYCU backup controller section in HYCU User Guide.
