Image Registry on cloud platforms and OpenStack

The Image Registry Operator installs a single instance of the Azure Red Hat OpenShift registry, and manages all registry configuration, including setting up registry storage.

Storage is only automatically configured when you install an installer-provisioned infrastructure cluster on AWS, GCP, Azure, or OpenStack.

After the control plane deploys, the Operator will create a default resource instance based on configuration detected in the cluster.

If insufficient information is available to define a complete resource, the incomplete resource will be defined and the operator will update the resource status with information about what is missing.

The Image Registry Operator runs in the openshift-image-registry namespace, and manages the registry instance in that location as well. All configuration and workload resources for the registry reside in that namespace.
