NetBackup™ Snapshot Manager Install and Upgrade Guide

Last Published: 2022-09-08

Product(s): NetBackup (10.1)

Prerequisites to install the extension on a managed Kubernetes cluster in Azure

Choose the Snapshot Manager image supported on Ubuntu or RHEL system that meets the Snapshot Manager installation requirements and create a host.
See Creating an instance or preparing the host to install Snapshot Manager.
It is not recommended to scale the cluster up or down when a job is running. It might cause the job to fail. Set the cluster size beforehand.
Verify that the port 5671 is open on the main Snapshot Manager host.
See Verifying that specific ports are open on the instance or physical host.
The public IP of the virtual machine scale set via which the node pool is configured has to be allowed to communicate through port 22, on the workloads being protected.
Install a Docker or Podman container platform on the host and start the container service.
See Table: Installing container platform.
Prepare the Snapshot Manager host to access Kubernetes cluster within your Azure environment.
- Install Azure CLI. For more information, refer to the Azure documentation.
- Install Kubernetes CLI. For more information, refer to the Kubernetes site.
- Login to the Azure environment to access the Kubernetes cluster by running this command on Azure CLI:
  # az login --identity
  # az account set --subscription <subscriptionID>
  # az aks get-credentials --resource-group <resource_group_name> --name <cluster_name>
Ensure that you create an Azure Container Registry or use the existing one if available, to which the Snapshot Manager images will be pushed (uploaded). See Azure documentation.
To run the kubectl and container registry commands from the host system, assign the following role permissions to your VM and cluster. You can assign a 'Contributor', 'Owner', or any custom role that grants full access to manage all resources.
- Navigate to your Virtual Machine > click Identity on the left > under System assigned tab, turn the Status to 'ON' > click Azure role assignment > click Add role assignments > select Scope as 'Subscription' or 'Resource Group' > select Role and assign the following roles : Azure Kubernetes Service RBAC Writer, AcrPush, Azure Kubernetes Service Cluster User Role, and Save.
- Navigate to your Kubernetes cluster > click Access Control (IAM) on the left > click Add role assignments > select Role as 'Contributor ' > Select Assign access to as 'Virtual Machines' > select your VM from the drop-down and Save.
Create a storage account in the same subscription and region your Kubernetes cluster is in, and create a file share into it. (Follow the default settings by Azure.) For more information, see Azure documentation.

While defining StorageClass consider using CSI provisioner for Azure Files with NFS protocol.

For example,

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: test-sc
parameters:
  skuName: Premium_LRS
  protocol: nfs
provisioner: file.csi.azure.com
reclaimPolicy: Retain
volumeBindingMode: WaitForFirstConsumer

Create a namespace for Snapshot Manager from the command line interface on host system:
# kubectl create namespace cloudpoint-system
Then create a new or use an existing managed Kubernetes cluster in Azure, and add a new node pool dedicated for Snapshot Manager use. Configure Autoscaling as per your requirement.
Ensure that Azure plug-in is configured.
See Microsoft Azure plug-in configuration notes.
