phistrom/l4d2 repository overview

⁠Dockerized Left 4 Dead 2 Dedicated Server

⁠Usage

You can start a Left 4 Dead 2 dedicated server with nothing else installed except Docker by running:

docker run -itd --net=host --name l4d2 -v /srv/l4d2:/l4d2 phistrom/l4d2

This will run the server with the default parameters of -port 27015 and -secure. The initial run of this container will download around 9.2GB of data before it will start. Subsequent runs will be much, much faster (provided you mount the same directory for /l4d2 each time).

Any additional parameters you specify will be passed along to the srcds_run command. For example, the following is equivalent to the first example:

docker run -itd --net=host --name l4d2 -v /srv/l4d2:/l4d2 phistrom/l4d2 -port 27015 -secure

To save time, the steamcmd runs +app_update without validate. To verify that the files for the dedicated server are not corrupt, pass in a non-empty VALIDATE environment variable to the container like this:

docker run -itd --net=host --name l4d2 -v /srv/l4d2:/l4d2 -e VALIDATE=1 phistrom/l4d2

This is equivalent to running steamcmd +app_update 222860 validate before starting srcds_run.

Be sure to mount the container's /l4d2 directory or else it will need to redownload all the game files and Steam client every time.

To see what your server is doing, you can run docker logs -f l4d2.
