Private registry

Some organization or specific teams don't want to share their custom container images with everyone for a reason. They still need a service to share Docker images, but just for internal usage. In that case, a private registry service can be useful. A private registry can be installed and configured as a service on a dedicated server or a virtual machine inside your network.

You can easily install a private Docker registry by running a Docker container from a public registry image. The private Docker registry installation process is no different from running a regular Docker container with additional options.
