Run commands on remote Docker host

This is how to connect to another host with your docker client, without modifying your local Docker installation or when you don't have a local Docker installation.

Enable Docker Remote API

First be sure to enable the Docker Remote API on the remote host. This can easily be done with a container.
For HTTP connection use jarkt/docker-remote-api.
For HTTPS connection use whiledo/docker-remote-api-tls.

Download docker client

If you don't have a local Docker installation, you need to download the docker client, which is a simple executable.
