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.

alias "c=xclip" # copy to X clipboard (register *)
alias "cs=xclip -selection clipboard" # copy to system wide clipboard (register +)
alias "v=xclip -o" # output copied content (paste)
alias "vs=xclip -o -selection clipboard" # paste from system wide clipboard (equivalent to `v -selection clipboard`)

First things first

Lets get some context first.
