Prerequisites
Azure Kubernetes cluster
Your Azure Kubernetes cluster must be created with appropriate network and configuration settings.
Supported Azure Kubernetes cluster version is 1.21.x and later.
Availability zone for AKS cluster must be disabled.
Two storage classes with the following configurations is required:
Storage class field
Data
Log
provisioner
disk.csi.azure.com
file.csi.azure.com
storageaccounttype
Premium_LRS
Premium_LRS
reclaimPolicy
Retain
Retain
allowVolumeExpansion
True
True
A Kubernetes Secret that contains the Snapshot Manager credentials is required.
Azure container registry (ACR)
Use existing ACR or create a new one. Your Kubernetes cluster must be able to access this registry to pull the images from.
Node Pool
You must have a dedicated node pool for Snapshot Manager created. The Azure autoscaling allows your node pool to scale dynamically as required.
It is recommended that you set the minimum node number to 1 or more to bypass some limitations in AKS.
User must enable system managed identity on the control node pool and add appropriate role for Snapshot Manager to operate.
Client machine to access AKS cluster
A separate computer that can access and manage your AKS cluster and ACR.
It must have Linux operating system.
It must have Docker daemon, the Kubernetes command-line tool (kubectl), and Azure CLI installed.
The Docker storage size must be more than 6 GB. The version of kubectl must be v1.19.x or later. The version of Azure CLI must meet the AKS cluster requirements.
If AKS is a private cluster, see Create a private Azure Kubernetes Service cluster.
Static Internal IPs
If the internal IPs are used, reserve the internal IPs (avoid the IPs that are reserved by other systems) for Snapshot Manager and add DNS records for all of them in your DNS configuration.
The Azure static public IPs can be used but is not recommended.
If Azure static public IPs are used, create them in the node resource group for the AKS cluster. A DNS name must be assigned to each static public IP. The IPs must be in the same location of the AKS cluster.
