Chapter 2. Image Registry Operator in Red Hat OpenShift Service on AWS

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

After the control plane deploys in the management cluster, the Operator creates a default configs.imageregistry.operator.openshift.io resource instance based on configuration detected in the cluster.

If insufficient information is available to define a complete configs.imageregistry.operator.openshift.io resource, the incomplete resource is defined and the Operator updates the resource status with information about what is missing.

The Image Registry Operator runs in the CONTROL_PLANE_NAMESPACE of the management cluster, and manages the registry instance in openshift-image-registry namespace of the cluster. All configuration and workload resources for the registry reside in that namespace.
