From the docs here
The storage for a given Pod must either be provisioned by a PersistentVolume Provisioner based on the requested storage class, or pre-provisioned by an admin.
There should be a StorageClass
which can dynamically provision the PV and mention that storageClassName
in the volumeClaimTemplates
or there needs to be a PV which can satisfy the PVC.

- metadata:
name: elasticsearch-data-persistent-storage

accessModes: [ "ReadWriteOnce" ]
