I am trying to use the following https://cloud.ibm.com/docs/containers?topic=containers-file_storage#add_file:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: ibmc-file
  labels:
    billingType: 'monthly'
    region: us-south
    zone: dal10
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 12Gi
  storageClassName: ibmc-file-silver

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: postgres
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: postgres
    spec:
      containers:
        - name: postgres
          image: postgres:11
          imagePullPolicy: Always
          ports:
            - containerPort: 5432
          envFrom:
            - configMapRef:
                name: postgres-config
          volumeMounts:
            - name: postgres-storage
              mountPath: /var/lib/postgresql/data
      volumes:
        - name: postgres-storage
          persistentVolumeClaim:
            claimName: ibmc-file

But the PVC is never "Bound" and gets stuck as "Pending".
