OpenShift Container Platform can build container images from your source code, deploy them, and manage their lifecycle. To enable this, OpenShift Container Platform provides an internal, integrated Docker registry that can be deployed in your OpenShift Container Platform environment to locally manage images.
During an initial installation of a full OpenShift Container Platform cluster, it is likely that the registry was deployed automatically during the installation process. If it was not, or if you want to further customize the configuration of your registry, see Deploying a Registry on Existing Clusters.
While it can be deployed to run as an integrated part of your full OpenShift Container Platform cluster, the OpenShift Container Platform registry can alternatively be installed separately as a stand-alone container image registry.
To install a stand-alone registry, follow Installing a Stand-alone Registry. This installation path deploys an all-in-one cluster running a registry and specialized web console.
