3.3. Persistent volumes

Each PV contains a spec and status, which is the specification and status of the volume, for example:

PersistentVolume object definition example

apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv0001


spec:
  capacity:
    storage: 5Gi


  accessModes:
    - ReadWriteOnce


  persistentVolumeReclaimPolicy: Retain


  ...
status:
  ...

1: Name of the persistent volume.
2: The amount of storage available to the volume.
3: The access mode, defining the read-write and mount permissions.
4: The reclaim policy, indicating how the resource should be handled once it is released.

You can view the name of a PVC that is bound to a PV by running the following command:

$ oc get pv <pv_name> -o jsonpath='{.spec.claimRef.name}'
