Gyula Fora commented on FLINK-26955:
------------------------------------
This ticket is a blocker for 1.1.0 but not for 1.0.0
> 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
> Priority: Blocker
> Fix For: kubernetes-operator-1.1.0
>
>
> 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.
