text: For a stateful container, you need the PV backing up the PVC requested for the pod. Other 
  scenarios showed the FlexVolume use with PowerVC, but this case uses the NFS attachment 
  for you to see another supported backend for volumes. This type of backend is still available if 
  not in use on any pod. The deployment file is shown in Example 7-11. Also, check the policy 
  of the PV is Retain and not Delete so the PVC can be used, even after migrated to another 
  cloud. This makes it available if and when the container is brought back. 
  
  Example 7-11 Yaml file for NFS backed PV on the Power Systems cluster 
  
  apiVersion: v1 
  kind: PersistentVolume 
  metadata: 
   name: appmongo-ibm-mongodb-dev-datavolume 
  spec: 
   persistentVolumeReclaimPolicy: Retain 
   storageClassName: manual 
   capacity: 
   storage: 2Gi 
   accessModes: 
   - ReadWriteMany 
   nfs: 
   server: dcocp1 
   path: /nfsmongofs/mongo 
  
  To verify the claim bounds to the intended PV, leave the PVC created, as shown in 
  Example 7-12.
