snapshot

Creating a snapshot from an exiting volume and restore it back

Note that we assume you correctly installed the csi-digitalocean driver, and it's up and running.

1. Create a pvc:

$ kubectl create -f pvc.yaml

2. Create a snapshot from the previous pvc:

$ kubectl create -f snapshot.yaml

At this point you should have a volume and a snapshot originating from that volume. You can observe the state of your pvc's and snapshots with the following command:

$ kubectl get pvc && kubectl get pv && kubectl get volumesnapshot

3. Restore from a snapshot:

To restore from a given snapshot, you need to create a new pvc that refers to the snapshot:

$ kubectl create -f restore.yaml

This will create a new pvc that you can use with your applications.

4. Cleanup your resources:

Make sure to delete your test resources:

$ kubectl delete -f pvc.yaml 
$ kubectl delete -f restore.yaml 
$ kubectl delete -f snapshot.yaml
