1. Get a CollectionID from the Steam Workshop
2. Get a Steam API Key
3. Set up environment variables. The available variables are:

G_HOSTNAME = "Garry's Mod"
GAMEMODE = "terrortown"
MAP = "gm_construct"
PASSWORD = ""
HOST_WORKSHOP_COLLECTION = ""
AUTHKEY = ""
ARGS = "" // can be used for any additional parameter, e.g. "+rcon_password xxxx" (see example)

Build:

docker build -t tttserver .

Example:

docker run -t -d -p 27005:27005/udp \
-p 27015:27015/udp \
-p 27006:27006/tcp \
-p 27015:27015/tcp \
-v ./server.cfg:/home/steam/gmodds/garrysmod/cfg/server.cfg tttserver \
--env PORT='27015' \
--env MAXPLAYERS='16' \
--env G_HOSTNAME='Garry\'s Mod' \

--env GAMEMODE='terrortown' \
--env MAP='gm_construct' \
--env HOST_WORKSHOP_COLLECTION='XXXX' \
--env AUTHKEY='XXXX' \

Docker Compose

Alternatively use:

docker-compose up

The docker-compose.yaml contains the example from above. Modify it in order to start the container with another configuration.
