ARO cluster creation fails with Internal Server Error and cannot be deleted.

Solution Verified - Updated -

Environment

  • Azure Red Hat OpenShift

Issue

  • ARO cluster created by limiting the permission on service principal. Thus the cluster creation fails with “Internal Server Error”.
  • By using az aro delete the cluster is not able to be deleted and gives “Internal Server Error”.

Resolution

  • Due to limiting the permission the deletion process fails on role assignments.
  • By providing service principal the ability to delete role assignments the cluster can be successfully deleted. (example: Owner permission)

Root Cause

  • Creating a cluster with a limited permissions model or custom permissions likely results in the cluster entering an unsupported state
  • Permission model should match the permission mentioned in the documentation
