Haha, nice! I was actually pondering building releases into Docker images at some point. I think the main issues will be around the mods area. It would be nice if you could --volume=src=/path/to/mods,dst=/enig_mods/ --env ENIG_MODS=/enig_mods/ or something so making tweaks, adding art, so on would be easier when running in a container.
I actually have a plan for this - as part of the container launch it's trivial to have a script that movea stuff about.
So you'd have a few volumes, like mods, art, misc (the places you might want to
put stuff basically) which when the container gets launched get copied to the right places within the Enigma structure...
I'll keep you posted, nearly got it working!
