      Epic Goal

      As an OpenShift installation administrator I must install OCP clusters in green-field environments where there isn't a pre-existing image registry. I need the installation process to include a registry that permits the cluster to install and run.

      I may optionally need additional content in the registry (operators, image streams).

      Why is this important?

      A common use case for agent-based deployments is a disconnected environment, where a registry needs to be mirrored in a location accessible to the clusters to be installed.

      BILLI requires a registry that exists before the clusters can be installed. It is common to not have one in the environment and having to create it as part of the installation of the first cluster in an environment.

      BILLI's goal is to make the installation as easy as possible while keeping the flexibility provided by UPI installations. Streamlining the installation of the registry along with the OpenShift installation is necessary to deliver BILLI's expected user experience.
