Docker image push over SSH (distributed)

Question

TL;DR Basically, I am looking for this:

docker push myimage ssh://myvps01.vpsprovider.net/

I am failing to grasp the rationale

Answer 1

I made a command line utility just for this scenario.

It sets up a temporary private docker registry on the server, establishes an SSH Tunnel from your localhost, pushes your image, then cleans up after itself.

The benefit of this approach over docker save is that only the new layers are pushed to the server, resulting in a quicker upload.

Oftentimes using an intermediate registry like dockerhub is undesirable, and cumbersome.

Install:

pip install docker-push-ssh

Example:

docker-push-ssh -i ~/my_ssh_key username@myserver.com my-docker-image

Biggest caveat is that you have to manually add your local ip to docker's insecure_registries config.
