StorageClass and PV creation for GKE

StorageClass Creation

• Create StorageClass yaml file with this code snippet

storageclass.yaml

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: mockingbird-sc
parameters:
  type: pd-standard
provisioner: kubernetes.io/gce-pd
allowVolumeExpansion: true
reclaimPolicy: Retain

• Create StorageClass with this command

kubectl apply -f storageclass.yaml  -n mockingbird
