Background / Issue

Installing the Operator is different for connected, partially connected, and fully disconnected environments. However, after the admin installs the Operator as required for their particular environment, the process of deploying RHDH on OCP or a support K8s platform is the same for all environments – with one caveat: 

There would be an additional prerequisite/step for disconnected ones if the mirror registry requires authentication.

If authentication against the mirror registry is required, then the user should configure the namespace where they want to install RHDH, in such a way that container images can be pulled from the mirror registry.

Recommended action

Add an additional, conditional prereq/step to the deployment procedures that applies only to users who are deploying in disconnected environments when the mirror registry requires authentication.
