Enable Docker Remote API with TLS client verification

Docker's Remote API can be secured via TLS and client certificate verification.
First of all you need a few certificates and keys:

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.
