This Draft PR isn't expected to be merged, but is a reference of what has to be changed in the legacy scheme
core/v1andapps/v1GO type definitions in order to allow generating, with thekubebuildercontroller-gentool, CRDs that can be successfully applied to a minimal apiserver likeKCP.This also required adding
listTypeandlistMapKeysannotations at all the places wherepatchStrategyand/orpatchMergeKeywere used, in order to have them correctly set when generating correspondingpatchStrategyand
patchMergeKeykubernetes extensions in openapiv2 definitions generated from CRDs(when legacy scheme resources are generated from CRDs) (see this change )
Having all the expected
patchStrategyandpatchMergeKeyannotations in the CRD generated openapiV2 schemais critical to enable Strategic Merge Patch for custom resources.
An example of CRDs generated by
kubebuildercontroller-genbased on these changes can be found in PR 4 in thekcpGH repository.
