Ohhhh for some reason I thought Alien Swarm's dedicated server was linux. Sorry! Nvm on that if it's going to be that much work. If you want to work on it, be my guest, but no pressure from me.
Toss me your steam name (I'm Veizour) and I'll send you the starbound copy. I got the "4 pack" and then one wasn't necessary because I got a divorce, so you get the "divorce special" (lolol!!)
As for time frame... hey, you're not running a business with this, I'm in no position to push. If you turn this around in a month, I'm fine and happy in just having the opportunity to run it in a container in the first place. 🙂 I really appreciate the work you do, and the "steam folder shared with all the dockers" you put out is so genius, really, nice design and setup!
