Volumes

You can create a volume at /home/steam/server to not redownload the game every time you make a change at the docker-compose file.

Configuration

You can set ANY conVar you want simply by prefixing the enviroment with CVAR_. So for example to set the RCON password set the enviroment variable CVAR_RCON_PASSWORD=password123. Try to avoid variables with the word CVAR_ and avoid = in it.

A list of available cvars can be found here.

If there is a new version of Metamod or Sourcemod and is not yet set in the image you can manually set the download URL in METAMOD_DL_URL and SOURCEMOD_DL_URL. It will only get update if the addon directory is empty.
