[jira] [Created] (FLINK-26955) Add CRD compatibility check

Gyula Fora created FLINK-26955:
----------------------------------

             Summary: Add CRD compatibility check
                 Key: FLINK-26955
                 URL: https://issues.apache.org/jira/browse/FLINK-26955
             Project: Flink
          Issue Type: Improvement
          Components: Kubernetes Operator
            Reporter: Gyula Fora
             Fix For: kubernetes-operator-1.0.0


Now with a preview release (almost) out. We should make sure that we do not introduce non-backward compatible changes to the CRD as it can cause serious issues on Kubernetes clusters.

There are 2 aspects to this:
 1. If we introduce a breaking change to already released CRDs we need to bump the version of the CRD (this is not the scope of the ticket)
 2. We should add a verification step in the build ensuring that the CRD changes are compatible

We should try to find a tool that can compare the openAPIV3Schema of the two CRDs and verify compatibility and integrate this into the maven build.
