We now need to update our stateful-set.yaml file to use the do-block-storage StorageClass. Under the StatefulSet spec (.spec), add a new field called volumeClaimTemplates with the following value:

apiVersion: apps/v1kind: StatefulSetmetadata: ...spec:  volumeClaimTemplates:  - metadata:      name: data    spec:      accessModes:      - ReadWriteOnce      resources:        requests:          storage: 2Gi      storageClassName: do-block-storage

This will use the do-block-storage class to dynamically provision 2 GB PersistentVolumeClaim Objects for any containers which mount it. The PVC is given the name data as a reference.

To mount it to a container, add a volumeMounts property under the spec property of the container spec:
