7. Check the Solution

   apiVersion: v1
   kind: PersistentVolumeClaim
   metadata:
     name: local-pvc
   spec:
     accessModes:
     - ReadWriteOnce
     resources:
       requests:
         storage: 500Mi
     storageClassName: local-storage
   

8. Check the Solution

   Pending
   

9. Check the Solution

   A Pod consuming the volume in not scheduled
   

10. Check the Solution

    The Storage Class called local-storage makes use of VolumeBindingMode set to WaitForFirstConsumer. This will delay the binding and provisioning of a PersistentVolume until a Pod using the PersistentVolumeClaim is created.

    apiVersion: v1
    kind: Pod
    metadata:
      name: nginx

        - name: local-persistent-storage
          persistentVolumeClaim:
            claimName: local-pvc
