Add helm.sh/resource-policy: keep in CRDs

[younusmohmmad]

Hi,

I noticed that the CRD manifest files in the OpenTelemetry Operator Helm chart repository (link) do not include the label:

helm.sh/resource-policy: keep

As a result, when the Helm chart is uninstalled, the CRDs are also deleted. Since CRDs are cluster-scoped resources, it is common to install them once and have multiple namespaces use the corresponding Custom Resources.

We have a use case where we want to install the CRDs in a separate namespace and ensure that they persist even if the operator Helm chart is deleted. This allows us to manage CRs in different namespaces without affecting the CRDs.

Would it be possible to update the Helm chart to add the helm.sh/resource-policy: keep annotation to the CRD manifests? This would prevent Helm from deleting the CRDs during uninstallation and better support this multi-namespace use case.

Thank you!

This seems like a valid use case, users would likely find it helpful. Given the complexity of CRD handling in Helm (HIP-0011), it makes sense to keep this disabled by default and allow users to opt in via value configuration.

A possible solution could be to support custom CRD annotations via:

crds:
  annotations: {}

Would make a good first-time contributor task.
