Hosting a multiplayer server with Docker?

[Julius]

Hi!

Due to some changes in my server setup (and stupid long contract periods), I have an more or less free x86 root server located in Germany that I could easily use to run a STK multiplayer server until the end of the year.

I found this page with some explanations:
https://github.com/supertuxkart/stk-cod ... WORKING.md

But I am wondering about two things mainly:
1. Is there a Docker image that I could use more easily? Ideally one available on Dockerhub that comes with sensible default settings?
2. Do I really need to open port 2759 on my server, or is there a way I can keep things running behind my Traefik.io reverse-proxy through a normal sub-domain? Note that UDP connections are not yet possible with Traefik 1.7.

(Due to a lot of other pending server work and limited time availability, point 1 would be quite vital as it would simplify hosting for me a lot).

Thanks for the help!

P.S.: any other server stuff you would need hosting for?

I don't think there exists a docker image, no, someone would need to make it

STK uses UDP packets, so if your software doesn't support UDP, it won't work.

Thanks for the answers! In that case I'll see if I can get Traefik2.0 working first (which should support UDP to some extend).

Edit: Well, thinking about it again... if it needs a open custom port anyways, then Traefik isn't really in the picture and the UDP connection would go directly to the STK server, right?
