Missing CRDs of the CSI Snapshotter in the "deploy" Ressources

[tiwalter]

Describe the bug

The csi-snapshotter container got the following errors, after deploying the deploy ressources of fs and rbd:

Root cause: Missing CRDs of the CSI Snapshotter. They can be found here: https://github.com/kubernetes-csi/external-snapshotter/tree/v6.1.0/client/config/crd.

You have to use the CRDs that fit to the deployed csi-snapshotter version that is deployed.
E.g. vor ceph-csi version v3.8.1, the csi-snapshotter version v6.1.0 is used.

Everything will be resolved, if you apply the CRDs.

Environment details

• Image/version of Ceph CSI driver : v3.8.1
• Kubernetes cluster version : v1.25.12
• Ceph cluster version : v16.2.7 (Pacific)

Steps to reproduce

Steps to reproduce the behavior:

1. Apply the resources in the deploy/cephfs/kubernetes directory (rbd also possible)
2. Check the logs of the csi-snapshotter
3. See errors

Expected behavior

The Kuberntes resources in the deploy directory must contain the needed CRDs for the csi-snapshotter.

Maybe the documentation needs to be improved , and https://github.com/ceph/ceph-csi/blob/devel/docs/snap-clone.md needs to be linked in some spots that make it easier to find?

[Rakshith-R]

The Kuberntes resources in the deploy directory must contain the needed CRDs for the csi-snapshotter.

The snapshot CRDs are an external dependency, mentioning it in deployment steps alone should be fine.
(It is actually expected to be provided by default in most latest kubernetes distros or made available by cluster admins)

Maybe the documentation needs to be improved , and https://github.com/ceph/ceph-csi/blob/devel/docs/snap-clone.md needs to be linked in some spots that make it easier to find?

Yes, we need to link that document in steps mentioned in

https://github.com/ceph/ceph-csi/blob/devel/docs/deploy-cephfs.md#deployment-with-kubernetes

and

@iPraveenParihar Can you please make the required changes ?
