Question

How do you clone a PersistentVolumeClaim in Kubernetes ?

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

Thanks @jkwiatkoski !

I will use this solution.

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/
