What is the problem?

commands.get_or_create_head_node is on the K8s operator's code path.
This method tries to copy a cluster config to the Ray head node, which is unnecessary for the operator.
The copy fails when running the operator on OpenShift which prevents the operator from working.
See #13567 (comment).

The solution is to modify commands.get_or_create_head_node to allow the operator to circumvent the violating rsync command.
