Scale replica count based latest VolumeSnapshot

General Discussions
1

Hi. If anyone know solutions please help me how I can do this.
I have “statefulset” which has following “volumeClaimTemplates” inside:
When I scale my replica count
“kubectl scale statefulset --replicas=2 my-statefulset”
, new “PVC” create from “volumesnapshot” object which name = “MySnapshot”

volumeClaimTemplates:
- apiVersion: v1
  kind: PersistentVolumeClaim
  metadata:
    name: data
  spec:
    accessModes:
    - ReadWriteOnce
    dataSource:
      apiGroup: snapshot.storage.k8s.io
      kind: VolumeSnapshot
      name: MySnapshot
    resources:
      requests:
        storage: 800Gi
    storageClassName: ebs-sc
    volumeMode: Filesystem

My question:
Is it possible to use dynamic name in field “volumeClaimTemplates.dataSource.name” ?
Clarify:
When new snapshot created modify statefulset and set volumeClaimTemplates.dataSource.name = new-name
Why I need this:
I have cronjob which automatically create snapshot with new name ex: MySnapshot_1, MySnapshot_2 …
And I need latest data into my “PVC” when new replica is created .
