      Epic Goal

      • The Cluster CAPI Operator enhancement (https://github.com/openshift/enhancements/pull/1845) introduces a CRD
          Compatibility Checker to prevent incompatible CRD updates. ACM needs to integrate with this mechanism when
          deploying and managing Cluster API resources.
      • Work Items:
          1. Review the CRD Compatibility Checker enhancement proposal
          2. Verify CRD installation process when ACM deploys HyperShift or Cluster API components
          3. Ensure proper namespace and object selectors are configured for ValidatingWebhook
          4. Implement compatibility checks during ACM-driven cluster deployments
          5. Collaborate with CCAPIO and HCP teams on CRD management coordination
          6. Update ACM documentation for CRD compatibility requirements
          7. Test multi-actor CRD scenarios (ACM + CCAPIO + HCP)

       

      Why is this important?

      • It is very unlikely we will be able to co-exist, and therefore need a way to handle the upgrade case safely to ensure neither side gets broken during the upgrade
