@kmala do you want to add anything into this PR that uses https://github.com/docker/docker-py/pull/1133/files ?

i would like to remove the docker login https://github.com/deis/controller/blob/master/rootfs/registry/dockerclient.py#L35 and use custom auth for both pull and push so that we don't save the auth information on the nodes but that can be done as part of separate PR if needed.

@kmala okay - I guess that means the other functions we use to support that - Hopefully with good enough error handling as well
