Installing the NetBackup Snapshot Manager extension on a managed Kubernetes cluster (AKS) in Azure
The NetBackup Snapshot Manager cloud-based extension can be deployed on a managed Kubernetes cluster in Azure for scaling the capacity of the NetBackup Snapshot Manager host to service a large number of requests concurrently.
Note:
Veritas does not recommend the registration of kubernetes extensions for Snapshot Manager in Kubernetes cluster.
Overview
Your Azure managed Kubernetes cluster should already be deployed with appropriate network and configuration settings, and with specific roles. The cluster must be able to communicate with NetBackup Snapshot Manager.
The required roles are:
Azure Kubernetes Service RBAC Writer, AcrPush, Azure Kubernetes Service Cluster User RoleFor supported Kubernetes versions, refer to the NetBackup Snapshot Manager Hardware Compatibility List (HCL).
Use an existing Azure Container Registry or create a new one, and ensure that the managed Kubernetes cluster has access to pull images from the container registry
A dedicated nodepool for NetBackup Snapshot Manager workloads needs to be created with manual scaling or 'Autoscaling' enabled in the Azure managed Kubernetes cluster. The autoscaling feature allows your nodepool to scale dynamically by provisioning and de-provisioning the nodes as required automatically.
NetBackup Snapshot Manager extension images (
flexsnap-deploy, flexsnap-core, flexsnap-fluentd, flexsnap-datamover) need to be uploaded to the Azure container registry.
