The problem is that a lone "hi" isn't universally used that way, and doesn't provide enough detail even when it is. I have no problem with messages like "Hi, are you free for a quick chat? I'll be around for the next 20 minutes."

Very cool. As others have said: "push/pull to the docker daemon as if it was a registry" is how docker should always have worked.

This is next level but I can imagine distributing resource usage across the cluster by pulling different layers from different peers concurrently.

Your script is the same idea as https://github.com/mkantor/docker-pushmi-pullyu (which is in the public domain, so feel free to steal).

docker-pushmi-pullyu does a vanilla `docker pull`[1] on the remote side, so you should be able to set `DOCKER_CONTENT_TRUST` in the remote environment to get whatever behavior you want (though admittedly I have not tested this).

If there's desire for an option to specify `--disable-content-trust` during push and/or pull I'll happily add it. Please file an issue if this is something you want.

> I'm curious why you implemented your own registry for this

Answering my own question: I think it's because you want to avoid the `docker pull` side of the equation (when possible) by having the registry's backing storage be the same as the engine's on the remote host.
