Install Docker Desktop https://www.docker.com/products/docker-desktop/ Make sure it is running

cd bullseye
docker build -t cs2base .
docker run -d --name=cs2base -e CS2_RCONPW=ENTERRCONPWHERE -v ./cs2mount:/home/steam/cs2-dedicated/ -p 27015:27015/tcp -p 27015:27015/udp -p 27020:27020/tcp cs2base

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/tcp -p 27015:27015/udp -p 27020:27020/tcp 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/tcp -p 27015:27015/udp -p 27020:27020/tcp 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
• 2GiB RAM
• 40GB of disk space for the container or mounted as a persistent volume on /home/steam/cs2-dedicated/

Environment Variables

Feel free to overwrite these environment variables, using -e (--env):

Server Configuration

CS2_SERVERNAME="changeme"   (Set the visible name for your private server)
CS2_IP=""                   (CS2 server listening IP address, 0.0.0.0 - all IP addresses on the local machine, empty - IP identified automatically)
CS2_PORT=27015              (CS2 server listen port tcp_udp)
CS2_RCON_PORT=""            (Optional, use a simple TCP proxy to have RCON listen on an alternative port.
                             Useful for services like AWS Fargate which do not support mixed protocol ports.)
CS2_LAN="0"                 (0 - LAN mode disabled, 1 - LAN Mode enabled)
CS2_RCONPW="changeme"       (RCON password)
CS2_PW="changeme"           (CS2 server password)
CS2_MAXPLAYERS=10           (Max players)
CS2_ADDITIONAL_ARGS=""      (Optional additional arguments to pass into cs2)

Note: When using CS2_RCON_PORT don't forget to map the port chosen with TCP protocol (e.g., add -p 27050:27050/tcp on the docker run command or add the port to the docker-compose.yml file).

Game Modes

CS2_GAMEALIAS=""            (Game type, e.g. casual, competitive, deathmatch.

CS2_GAMETYPE=0              (Used if CS2_GAMEALIAS not defined. See https://developer.valvesoftware.com/wiki/Counter-Strike_2/Dedicated_Servers)
CS2_GAMEMODE=1              (Used if CS2_GAMEALIAS not defined. See https://developer.valvesoftware.com/wiki/Counter-Strike_2/Dedicated_Servers)
CS2_MAPGROUP="mg_active"    (Map pool)
CS2_STARTMAP="de_inferno"   (Start map)

Bots

CS2_BOT_DIFFICULTY=""       (0 - easy, 1 - normal, 2 - hard, 3 - expert)

CS2_BOT_QUOTA_MODE=""       (fill, competitive)

CSTV/SourceTV

TV_ENABLE=0                 (0 - disable, 1 - enable)
TV_PORT=27020               (SourceTV/CSTV port to bind to)
TV_AUTORECORD=0             (Automatically record all games as CSTV demos: 0=off, 1=on)
TV_PW="changeme"            (CSTV password for clients)
TV_RELAY_PW="changeme"      (CSTV password for relay proxies)
TV_MAXRATE=0                (Max CSTV spectator bandwidth rate allowed, 0 == unlimited)
TV_DELAY=0                  (CSTV broadcast delay in seconds)

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!
