Is there a way to post process the generated CRD?

[matteriben]

I'd like the generated CRD to include logical constraints using [ "oneOf", "allOf", "anyOf", "not" ]. Currently I don't believe this is something the generator can provide. If there is a way to post process the generated CRD before its applied that could offer a pathway to include these constraints.

I believe I found my answer and it seems this can be done by through an extension at build time.

@matteriben sorry, this somehow slipped by me… Would you mind describing your solution? Maybe there's something we could add in QOSDK to make this and future similar use cases easier to deal with?

@metacosm
What I was looking for was a way to extend the existing CRD generator build-step perhaps by implementing some post-processor interface or something like that.

The pathway I found in the meantime is to extend the build system (maven or in my case gradle) with a post-processing stage.

@matteriben would it help if QOSDK provided a way to add a CRD post-processor that would be inserted before the CRD is serialized to disk? Most likely in the form of a CDI bean implementing a given interface.
