Found this question when looking for a way to copy an image from local docker registry on host-a to local docker registry on host-b. If you have SSH access to host-b this should work:

user@host-a:~$ docker image save "repository:tag" | ssh host-b "docker image load"

You can pull the image, tag it and push it to the new registry.

Example:

docker pull old-registry/app:some_tag
docker tag old-registry/app:some_tag new-registry/app:some_tag
docker push new-registry/app:some_tag

Can be done with https://github.com/containers/skopeo

Example for the README:

skopeo copy docker://quay.io/buildah/stable docker://registry.internal.company.com/buildah

The advantage is that Skopeo does not require Docker on the machine it runs on.
