OpenRPG running in Docker

Introduction

I've been running a D&D game for years using OpenRPG. Sadly,
with every OS upgrade it gets more and more difficult to
get OpenRPG running with new versions of Python.

And then I had a revelation - Docker lets me run OpenRPG without
needing to spend hours getting the right (i.e old and cranky)
combination of python and wxPython installed and working.

Instructions

The easiest thing to do is to install and verify docker on your system, and then :

xhost +
docker run --rm -v /tmp/.X11-unix:/tmp/.X11-unix -v /home/myname/openrpg/myfiles:/openrpg/myfiles -e DISPLAY=unix$DISPLAY ksonney/docker-openrpg

This will use a local myfiles directory (in case you already had data).
You can omit the myfiles volume if you just want to run the client and connect to a remote game.
