Chapter 7. Deploy a Docker Registry
Openshift provides an internal, integrated Docker registry that can be deployed to locally manage images. OpenShift uses the docker-registry to store, retrieve, and build Docker images, as well as deploy and manage them throughout their lifecycle.
From OpenShift 3.2 and onwards, the installer creates a default registry.
Delete the default registry using the following command:
oc delete all -l docker-registry=default
Create the docker-registry service in the default project using the registry service account:
$ oadm registry
The OpenShift documentation contains detailed information on docker registry.
