Locally here means the locally on your laptop locally, not locally on your VPS. Contrary to popular opinion, I believe your source code shouldn't be on your prod machine - a docker image is all you need. Lots of other projects push your code to VPS to build the image there then use it. I see no point in doing that...

The docker registry can be avoided by exporting/importing the docker image over ssh.

At the cost of losing layers reusage at transport time.
