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.

How to use this image

Hosting a simple game server

Initial one-time setup

As of now, you can't download the CS2 dedicated server using +login anonymous, as it's part of the CS2 client.

1. Create a fresh Steam account and add CS2 to its library or use your own. [Optional if you already have an account]
   

2. Create required named volume:

$ docker volume create steamcmd_login_volume # Location of login session

3. Activate the SteamCMD login session, if required enter your e-mail Steam Guard code (this will permanently save your login session in steamcmd_login_volume). Replace the following fields before executing the command:

• [STEAMUSER] - steam username
• [ACCOUNTPASSWORD] - steam account password

$ docker run -it --rm \
    -v "steamcmd_login_volume:/home/steam/Steam" \
    cm2network/steamcmd \
    bash /home/steam/steamcmd/steamcmd.sh +login [STEAMUSER] [ACCOUNTPASSWORD] +quit

Running a CS2 dedicated server

4. Run using a bind mount for data persistence on container recreation. Replace the following fields before executing the command:

• [STEAMUSER] - steam username (no password required, if you completed step 1)

$ mkdir -p $(pwd)/cs2-data
$ chmod 777 $(pwd)/cs2-data # Makes sure the directory is writeable by the unprivileged container user
$ docker run -d --net=host \
    -v $(pwd)/cs2-data:/home/steam/cs2-dedicated/ \
    -v "steamcmd_login_volume:/home/steam/Steam" \
    --name=cs2-dedicated -e STEAMUSER=[STEAMUSER] cm2network/cs2

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