VolumeSnapshot support

Hi,

first of all thanks for the great project. I’m running a 3 nodes k8s cluster on rpi4 and it’s a fantastic to have such powerful k8s just running on a desk at home.

I’m using quite a few PVC on this clusters and it would be amazing if I could use VolumeSnapshot too.

I’m running Microk8s 1.19 and I think Snapshot should be supported from 1.17.

This is what I see when I try to install:

ubuntu@rpi-one:~/cardano-node-builder$ cat snap-test.yaml
---
apiVersion: snapshot.storage.k8s.io/v1beta1
kind: VolumeSnapshot
metadata:
  name: new-snapshot-test
  namespace: cardano-relay
spec:
  source:
    persistentVolumeClaimName: cardano-node-tau
ubuntu@rpi-one:~/cardano-node-builder$ k apply -f snap-test.yaml
error: unable to recognize "snap-test.yaml": no matches for kind "VolumeSnapshot" in version "snapshot.storage.k8s.io/v1beta1"

Am I doing anything wrong?

Hi, for those following this but don’t want to apply something beta/modified, I actually found the openebs to be very useful. I’m not related to the project but the setup is extremely simple and you get some better grip on the used storage https://github.com/openebs/zfs-localpv

The documentation mentions to modify the paths when you are using microk8s. You can modify the paths quite easily with a sed (hence why I’m posting, for my own ref).

wget https://openebs.github.io/charts/zfs-operator.yaml
cat zfs-operator.yaml | sed  's#/var/lib/kubelet/#/var/snap/microk8s/common/var/lib/kubelet/#g' > zfs-operator-microk8s.yaml

You will have to also apply the storage snapshot yaml found here if you want to have snapshot support https://github.com/openebs/zfs-localpv/blob/master/docs/snapshot.md
