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
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
will be defined and the operator will update the resource status with
information about what is missing.
The Image Registry Operator runs in the
and manages the registry instance in that location as well. All configuration
and workload resources for the registry reside in that namespace.
