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, 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
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.
