This image contains an implementation of the Docker Registry HTTP API V2 for use with Docker 1.6+. See github.com/docker/distribution for more details about what it is.
Run a local registry: Quick Version
$ docker run -d -p 5000:5000 --restart always --name registry registry:2
Now, use it from within Docker:
$ docker pull ubuntu $ docker tag ubuntu localhost:5000/ubuntu $ docker push localhost:5000/ubuntu

Specifically, the section regarding deployment has pointers for more complex use cases than simply running a registry on localhost.
