What is Counter-Strike 2?

For over two decades, Counter-Strike has offered an elite competitive experience, one shaped by millions of players from across the globe. And now the next chapter in the CS story is about to begin. This is Counter-Strike 2. This Docker image contains the dedicated server of the game.

CS2

How to use this image

Hosting a simple game server

Running using Docker:

$ docker run -d --name=cs2 -p 27015:27015 -p 27020:27020 joedwards32/cs2

Running using a bind mount for data persistence on container recreation:

$ mkdir -p $(pwd)/cs2-data
$ chmod 777 $(pwd)/cs2-data # Makes sure the directory is writeable by the unprivileged container user
$ docker run -d --name=cs2 -v $(pwd)/cs2-data:/home/steam/cs2-dedicated/ -p 27015:27015 -p 27020:27020 joedwards32/cs2

or using docker-compose, see examples:

# Remember to update passwords in your compose file
$ docker compose --file examples/docker-compose.yml up -d cs2-server

You must have at least 40GB of free disk space! See System Requirements.

The container will automatically update the game on startup, so if there is a game update just restart the container.

Configuration

System Requirements

Minimum system requirements are:

• 2 CPUs

Customizing this Container

Pre and Post Hooks

The container includes two scripts for executing custom actions:

• /home/steam/cs2-dedicated/pre.sh is executed before the CS2 server starts
• /home/steam/cs2-dedicated/post.sh is executed after the CS2 server stops

When using a persient volume mounted at /home/steam/cs2-dedicated/ you may edit these scripts to perform custom actions, such as enabling metamod.

This container leans heavily on the work of CM2Walki, especially his SteamCMD container image. GG!
