The customer wants to monitor an Openshift host (DaemonSet for OpenShift 3.7). However, they don't have access to the RHCC. Is it mandatory for the Docker image to be provided by RHCC or can I find that image in another Docker repository?
From the documentation, it seems to be mandatory.
There are multiple deployment strategies but the required method is not viable for you I would open a support ticket to see what can be done.
