Pre-Fortress 2 Server with Docker

A Docker image to streamline and easily deploy new Pre-Fortress 2 servers. Requires Docker to be installed. Based off the official Linux server guide. The image is rebuilt automatically every week on Sunday with all the latest updates for everything.

Simple Guide - Setting up and deploying a simple server

First off, you'll want to install Docker, this tutorial assumes you will be using Docker on some flavor of Linux, and know some basic stuff about Linux.
Next, you'll want to clone/download this repo, cd into the cloned repo and run docker compose up to run the server attached to your terminal.
The server will start up, first updating the SDK, then Pre-Fortress 2, and then properly start the server. You will see a message about root access, this is safe to ignore. You may also see a message about no map being specified, this is safe to ignore if a map is selected in autoexec.cfg (which there is by default, koth_crossover).
The output will say what its public IP is, indicating that the server is up and running an accessible. You can send a keyboard interrupt (ctrl+c) to stop the server.

Notes:

If you want to run the server detached, you can run docker compose up -d to detach it from your terminal; you'll want to run docker compose stop if you want to stop the server if it's detached.
You can access the server's files with the volumes created by Docker visiting Docker Volumes instead of binds
You can run docker compose down to remove the container and volumes for the server.
You will still need to forward the ports 27005 and 27015 yourself on your router.

Expert Guide - SourceMod, custom content, and more

If you know Docker pretty well or need some specific changes to the setup, you can change the docker-compose.yml. For example, if you'd like to run the server with SourceMod for plugins and better server management, edit the compose file to change the image tag from "latest" to "latest-sm".

To add/edit files to/on your server, certain directories for the server are exposed as Docker volumes, accessible at the /var/lib/docker/volumes/ directory. There are volumes for the custom folder, cfg folder, and SourceMod folder, and you can use these to create more personalized servers for Pre-Fortress 2.

The Pre-Fortress 2 Docker Image bases the image off itself to simply update the files of the game. This is done with the Dockerfile.of file in the dockerfiles folder, however if you need to build the image from scratch the Dockerfile.cache file will be what you need to use.

Troubleshooting

If you need to reset your images use docker image prune -a and if you need to reset containers use docker container prune. You can also use docker image or container for more options if you would like to remove specific images or containers instead.

Testing local images

For PF2 we tested the docker images offline. You can create them by running docker build . -t pfsv:latest -f ./dockerfiles/Dockerfile.cache and then running docker compose up. This will run the server without connecting to docker's servers. In docker-compose.yml change image: prefortress2/pfsv:latest to image: pfsv:latest.
