Dockerized remote setup

This lets me install my settings and preferred user tools on a new machine by launching a docker image, rather than configuring stuff by hand. I use most machines remotely, so this image just runs an SSH server and headless xpra.

Usage:

$ cp ~/.ssh/id_rsa.pub authorized_keys
$ vim Dockerfile                # change ENV user= to your username
$ sudo docker build -t me .
$ sudo docker run -p 2222:22 -v /mnt:/some/path -d me

You should then be able to SSH into the server and be dropped into a persistent tmux. Any X applications you run should also persist in an xpra server running on display 100.
