----------------------------------
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.
