Custom conVars

You can set ANY other variable by just prefixing the conVar with CVAR_. So for example if you want to set mp_disable_autokick 1 just set the enviroment variable CVAR_MP_DISABLE_AUTOKICK to 1. Upper or lower case is ignored.

Minimum configuration

The minimum variables you should set for a somewhat working game is is GSLT, MAP and maybe GAMEMODE. You can also check out the example docker-compose.yml.

Misc

Because docker-compose recreated the container every time you update a varaible you can mount /home/steam/server to a volume so that you dont have to redownload the server every time you change something.

The game gets updated every time the image restarts.
