How Volume Populator Process Works?
The following diagram shows how KubeStash restores backup data into a specific volume and attaching it to user-provided Persistent Volume Claims (PVCs) for usage of various workload applications.
The Volume Populator process consists of the following steps:
KubeStash operator watches for
PVCs.When the operator finds a
PVCwithspec.dataSourceRefset and refers to a KubeStashSnapshotobject, it starts populating thisPVCby creating a volume populatorJobthat mounts a temporaryPVC.Then the populator Job restores the referred
Snapshotinto this 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.
