      Epic Goal

      • Allow the custom DNS feature to be enabled on day 2 by modifying the Infrastructure CR.

      Why is this important?

      ARO already has its own mechanism for implementing custom DNS. Enabling the in-cluster DNS for new installs will only partially enable this mechanism to be turned off. To get rid of it entirely, existing clusters must be switched over to use the new custom DNS functionality for core OCP.

      Scenarios

      1. ...

      Acceptance Criteria

      • CI - MUST be running successfully with tests automated
      • Release Technical Enablement - Provide necessary release enablement details and documents.

      Open questions::

      1. How do we update the pointer ignition to reference the IP address of the internal load balancer instead of api-int for fetching the ignition?
