Provide a helm chart just for the CRDs like karpenter does

[ecerulm]

Proposal

The CRDs can today be installed from the regular helm chart kedacore/keda but it's often good to have the the crds as an independent helm chart for example Karpenter provider karpenter and karpenter-crd

Use-Case

The rationale for that is for upgrades see Karpenter CRD Upgrades

In karpenter , the karpenter helm chart only installs the CRDs on first installation, subsequent chart upgrades will not add or remove CRDs, even if the CRDs have changed.

Having a separate helm chart for CRDs gives more control and allows me to deploy the CRDs from terraform (today this project provides the crds as a single file like https://github.com/kedacore/keda/releases/download/v2.13.1/keda-2.13.1-crds.yaml which is harder to deploy from a terraform perspective it's much easier if it's a helm release.

In any case it should be stated (here or in the documentation) what happens with the CRDs during an helm upgrade. It's my understanding by looking at the source code https://github.com/kedacore/charts/blob/main/keda/templates/crds/crd-triggerauthentications.yaml that today keda helm chart will always overwrite.

Is this a feature you are interested in implementing yourself?

Maybe

Anything else?

WDYT @tomkerkhove @zroubalik ?

[tomkerkhove]

No objections, as long as Helm chart updates effectively update CRDs as well! I know there were some issues in that direction as part of kedacore/charts#226

Are you willing to contribute this @ecerulm ?
