Creating Persistent Storage Volumes Statically

You can statically create a persistent volume (PV) in a TKG 2.0 cluster using a persistent volume claim (PVC) from the Supervisor.

Persistent Volume Definition

Below is an example definition for a static persistent volume (PV). The definition requires a storage class and a volume handle. The volumeHandle is the name of a persistent volume claim (PVC) that is created on Supervisor in the same vSphere Namespace where the target TKG cluster is provisioned. This PVC must not be attached to any pod.

Use the following command to get the storageClassName.

kubectl get storageclass

For volumeHandle, enter the name of the PVC on Supervisor.

apiVersion: v1
   kind: PersistentVolume
   metadata:
     name: static-tkg-block-pv
     annotations:
       pv.kubernetes.io/provisioned-by: csi.vsphere.vmware.com
   spec:
     storageClassName: gc-storage-profile
     capacity:
       storage: 2Gi
     accessModes:
       - ReadWriteOnce
     persistentVolumeReclaimPolicy: Delete
     claimRef:
       namespace: default
       name: static-tkg-block-pvc
     csi:
       driver: "csi.vsphere.vmware.com"
       volumeAttributes:
         type: "vSphere CNS Block Volume"
       volumeHandle: "supervisor-block-pvc-name"  #Enter the PVC name from Supervisor.

Use the following to create the PV.

kubectl apply -f redis-leader-pvc.yaml -n guestbook

Persistent Volume Claim (PVC) for Statically Defined PV

If you have deployed Supervisor across zones.

Set the storageClassName to the same value as in the PV.

kind: PersistentVolumeClaim
   apiVersion: v1
   metadata:
     name: static-tkg-block-pvc
   spec:
     accessModes:
       - ReadWriteOnce
     resources:
       requests:
         storage: 2Gi
     storageClassName: gc-storage-profile
     volumeName: static-tkg-block-pv

Verify that the PVC is bound to the PV that you created.

kubectl get pv,pvc
