I created this Docker image for my own servers, but have released it for anyone to use.

How to use this image
Hosting a simple game server
Running on the host interface (recommended):
$ docker run -d -it --net=host --name=tf2classic -e SRCDS_TOKEN={YOURTOKEN} litltoast/tf2-classic
Running using a bind mount for data persistence on container recreation:
$ mkdir -p $(pwd)/tf2-data
$ chmod 777 $(pwd)/tf2-data # Makes sure the directory is writeable by the unprivileged container user
$ docker run -d -it --net=host -v $(pwd)/tf2-data:/home/steam/tf2classic-dedicated/ --name=tf2classic -e SRCDS_TOKEN={YOURTOKEN} litltoast/tf2-classic
Running multiple instances (increment SRCDS_PORT and SRCDS_TV_PORT):
$ docker run -d -it --net=host --name=tf2classic-2 -e SRCDS_PORT=27016 -e SRCDS_TV_PORT=27021 -e SRCDS_TOKEN={YOURTOKEN} litltoast/tf2-classic
SRCDS_TOKEN is required to be listed & reachable. Generate one here using AppID 243750:
https://steamcommunity.com/dev/managegameservers
SRCDS_WORKSHOP_AUTHKEY is required to use workshop features:
https://steamcommunity.com/dev/apikey
It’s also recommended to use “–cpuset-cpus=” to limit the game server to a specific core & thread.

The Making of the Image
The original image from cm2network used git clone to pull the entry.sh script changes into the image. This meant that new containers would not get the entry script changes, unless the whole image was scrapped and rebuilt. Docker doesn’t rebuild images if the Dockerfile hasn’t changed, but the image needs to change if the script has changed. The solution was to simply use the COPY command in the Dockerfile. Besides that, making the Docker image was smooth. I plan on making one for my Discord bot next and to find other cool services to spin up on my home server.
