How does OpenShift manage potential incompatibilities related to operator versions?

Solution Verified - Updated -

Issue

  • Is there any mechanism to control whether a specific version of an operator is compatible with a particular OpenShift release?
  • In case there is a potential incompatibility, would OpenShift block cluster and/or operator upgrades?
  • Kubernetes 1.22 (and OpenShift 4.9, based on it) will stop serving some deprecated API versions. Will this create potential issues on the functionality of the operators using those versions?
  • After upgrading the OCP cluster the alert ClusterNotUpgradeable is firing with the following error even if the upgrade finished successfully without any issue.:

    ClusterServiceVersions blocking cluster upgrade: ${NAMESPACE}/${OPERATOR} is incompatible with OpenShift minor versions greater than 4.X
    

Environment

  • Red Hat OpenShift Container Platform (OCP) 4.x.
