Add support for annotations on Deployment/StatefulSet resources in DruidNodeSpec #145

SamWheating · 2024-02-29T21:10:38Z

Fixes #142

Description

Adding a ReplicationControllerAnnotations field to the DruidNodeSpec schema. This allows users to specify annotations to be applied to the StatefulSet / Deployment object.

I'm not 100% sure of the naming - what do you think? I didn't want to call it StatefulSetAnnotations since the user can opt for a deployment instead.

Also regenerated the API docs, which led to a huge diff as it appears they weren't regenerated after #53 (hence the huge diff)

This PR has:

been tested on a real K8S cluster to ensure creation of a brand new Druid cluster works.
been tested for backward compatibility on a real K*S cluster by applying the changes introduced here on an existing Druid cluster. If there are any backward incompatible changes then they have been noted in the PR description.
added comments explaining the "why" and the intent of the code wherever would not be obvious for an unfamiliar reader.
added documentation for new or modified features or behaviors.

I haven't tested this on a real kube cluster, but all of the e2e tests run. Is that sufficient for an overall minor/straightforward change?

Can we also add this field in druidSpec ?
You can merge the annotations if specified in both the spec druid nodeSpec and druidSpec. The latter is cluster scoped. Its common to all druid nodes.

Done ✅

Any strong preference on how these are merged? In my opinion it makes sense for the finer-grained DruidNodeSpec-level annotations to override the DruidSpec-level annotations (see implementation), but I see that we do the opposite with PodLabels.

@SamWheating does Reddit use the operator? if so, can we add you as users in the ADOPTERS.md ?

does Reddit use the operator?

Not in any official capacity, this work was completed on my own time and mostly just out of personal interest.

Hi @SamWheating just fix the function name and I'll approve
