Asked by Mike P.O

Hello all !

According to Kubernetes official documentation, it’s possible to clone a PVC from another PVC.

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: cloned-pvc
spec:
  dataSource:
    name: existing-src-pvc-name
    kind: PersistentVolumeClaim
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi

On my DigitalOcean cluster, kubectl apply with above config seems to work, but i got the status PENDING state for the PVC indefinitely.

Thanks for help,

Mike

Hi there!

One way to accomplish this would be using volumesnapshot objects. This will allow you to take a snapshot of a pv, and then create a a new volume based off the snapshot of that pv.

You can find documentation on how to accomplish this here: https://kubernetes.io/docs/concepts/storage/volume-snapshots/
