How Volume Populator Process Works?

KubeStash operator watches for
PVCs.When the operator finds a
PVCwithspec.dataSourceRefset and refers to a KubeStashSnapshotobject, it creates a volume populatorJobthat mounts a temporaryPVC.Then the populator Job restores the referred
Snapshotinto the temporary PVC.Once the restoration process is complete, the KubeStash operator deletes this populator
Joband temporaryPVC, and binds thePVcontaining the restored data with the desiredPVC.
