# 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](https://store.steampowered.com/app/730/CounterStrike_2/). This Docker image contains the dedicated server of the game. logo # How to use this image ## Hosting a simple game server Running on the *host* interface (recommended):
```console $ docker run -d --net=host --name=cs2 -e STEAMUSER={YOUR_STEAM_USER} -e STEAMPASS={YOUR_STEAM_PASSWD} git.zio.sh/astra/cs2:latest ``` Running using a bind mount for data persistence on container recreation: ```console $ 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/ \ --name=cs2-dedicated \ -e STEAMUSER= \ -e STEAMPASS= \ git.zio.sh/astra/cs2:latest ``` `STEAMUSER` and `STEAMPASS` **are required as unlike CS:GO, CS2 can not be downloaded anonymously (at time of writing).** `STEAMGUARD` **must be used to provide your more recent Steam Guard key if Steam Guard is enabled on your account.** **The container will automatically update the game on startup, so if there is a game update just restart the container.** # Configuration ## System Requirements Please note that you need approximately 1.5g of free RAM. If this is not available, container will crash with err 137. ## Environment Variables Feel free to overwrite these environment variables, using -e (--env) or --env-file (recommended): ### SteamCMD ```dockerfile STEAMUSER="changeme" (Steam User for SteamCMD.) STEAMPASS="changeme" (Password for Steam User.) STEAMGUARD="" (Optional, Steam Guard key if enabled. Use your most recent Steam Guard key.) ``` ### Server Configuration ```dockerfile SRCDS_TOKEN="" (Game Server Token from https://steamcommunity.com/dev/managegameservers) CS2_SERVERNAME="changeme" (Set the visible name for your private server) CS2_CHEATS=0 (0 - disable cheats, 1 - enable cheats) CS2_SERVER_HIBERNATE=0 (Put server in a low CPU state when there are no players. 0 - hibernation disabled, 1 - hibernation enabled n.b. hibernation has been observed to trigger server crashes) 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" (Optional, 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 ```dockerfile CS2_GAMEALIAS="" (Game type, e.g. casual, competitive, deathmatch. See https://developer.valvesoftware.com/wiki/Counter-Strike_2/Dedicated_Servers) 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. Ignored if workshop maps are defined.) CS2_STARTMAP="de_inferno" (Start map. Ignored if workshop maps are defined.) ``` ### Bots ```dockerfile CS2_BOT_DIFFICULTY="" (0 - easy, 1 - normal, 2 - hard, 3 - expert) CS2_BOT_QUOTA="" (Number of bots) CS2_BOT_QUOTA_MODE="" (fill, competitive) ``` ### CSTV/SourceTV ```dockerfile 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) ``` ### Logs ```dockerfile CS2_LOG="on" ('on'/'off') CS2_LOG_MONEY=0 (Turns money logging on/off: 0=off, 1=on) CS2_LOG_DETAIL=0 (Combat damage logging: 0=disabled, 1=enemy, 2=friendly, 3=all) CS2_LOG_ITEMS=0 (Turns item logging on/off: 0=off, 1=on) ``` ### Steam Workshop Support for Steam Workshop is experimental! ```dockerfile CS2_HOST_WORKSHOP_MAP="" (Steam Workshop Map ID to load on server start) CS2_HOST_WORKSHOP_COLLECTION="" (Steam Workshop Collection ID to download) ``` If a Workshop Collection is set, maps can be selected via rcon. E.g: ``` ds_workshop_listmaps ds_workshop_changelevel $map_name ``` # Customizing this Container ## Debug Logging If you want to increase the verbosity of log output set the `DEBUG` environment variable: ```dockerfile DEBUG=0 (0=none, 1=steamcmd, 2=cs2, 3=all) ``` ## Validating Game Files If you break the game through your customisations and want steamcmd to validate and redownload then set the `STEAMAPPVALIDATE` environment variable to `1`: ```dockerfile STEAMAPPVALIDATE=0 (0=skip validation, 1=validate game files) ``` ## 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. Alternatively, you may have docker mount files from outside the container to override these files. E.g.: ``` -v /path/to/pre.sh:/home/steam/cs2-dedicated/pre.sh ``` ## Overriding Game Mode Defaults The default configurations for each game mode are stored in `/home/steam/cs2-dedicated/game/csgo/cfg/`. For example, the Competitive mode defaults are set by `gamemode_competitive.cfg`. When using a persistent volume mounted at `/home/steam/cs2-dedicated/`, these defaults can be overridden by adding your own settings to `gamemode_competitive_server.cfg`. ``` // Game Mode Competitive Server Overrides mp_maxrounds 16 // Shorter games ``` ## Customisation Bundle The container can be instructed to download a extract a Tar Gzip bundle, Tar or Zip archive of configuration files and other customisations from a given URL. ```dockerfile CS2_CFG_URL="" (HTTP/HTTPS URL to fetch a Tar Gzip bundle, Tar or Zip archive of configuration files/mods) ``` # Credits This container leans heavily on the work of [CM2Walki](https://github.com/CM2Walki/), especially his [SteamCMD](https://github.com/CM2Walki/steamcmd) container image.
