Configuration for Storage Classes in Azure

If you are using Azure VMs for your nodes, you can use Azure files as a StorageClass for the cluster.

In order to have the Azure platform create the required storage resources, follow these steps:

  1. Configure the Azure cloud provider.
  2. Configure kubectl to connect to your cluster.

  3. Copy the ClusterRole and ClusterRoleBinding manifest for the service account:

    1. ---
    2. apiVersion: rbac.authorization.k8s.io/v1
    3. kind: ClusterRole
    4. metadata:
    5.   name: system:azure-cloud-provider
    6. rules:
    7. - apiGroups: ['']
    8.   resources: ['secrets']
    9.   verbs:     ['get','create']
    10. ---
    11. apiVersion: rbac.authorization.k8s.io/v1
    12. kind: ClusterRoleBinding
    13. metadata:
    14.   name: system:azure-cloud-provider
    15. roleRef:
    16.   kind: ClusterRole
    17.   apiGroup: rbac.authorization.k8s.io
    18.   name: system:azure-cloud-provider
    19. subjects:
    20. - kind: ServiceAccount
    21.   name: persistent-volume-binder
    22.   namespace: kube-system

  4. Create these in your cluster using one of the follow command.

    1. # kubectl create -f <MANIFEST>
