@Stale bot leave it open

With #2820 merged, we can now plan on adding the cluster spec to the existing rook-ceph helm chart instead of creating a whole new chart. This will be a great simplification since users generally want to manage a single cluster with a single operator.

We can leverage the changes in #1676 and now apply it to the existing helm chart and we will be most of the way there. The cluster crd has changed quite a bit since that PR was opened, so we will also need to update to the latest crd schema.

2 years later ? :)

My plan would be to just have it be a "wrapper" for the CephCluster object in the values.yaml and keeping it separate to the rook-ceph-operator Chart so we can rely on the operator like that as a dependencies.

@galexrt
There is such a wrapper ready.

@maver1ck Yeah I know that one, but we need one specific for the Rook CephCluster object to be able to easily add "easy to use options / toggles" later down the road.

I'll start the chart as a specific for CephCluster wrapper and later on as users will hopefully contribute to it so that "easy use options" (e.g., "this is a test cluster" toggle, etc) can be added to it.

[maver1ck]

If you need any testing please let me know.

To update on this issue, I'm in the process of writing a design document to move all Helm charts to a separate repo, so the Helm charts are able to "move" / release without being bound to the Rook releases directly.
The Helm charts have the appVersion which can / should be used then to indicate the Rook version they are targeted for.
I should have that document finally ready tomorrow / weekendish for review.
