The environment variables are split into three sections: Meta, Server, and Battle Eye. Server variables translate to configuration options found in the typical serverDZ.cfg file and are used to generate such a file for the server. Meta variables control all other aspects of the server, such as Steam configuration, server files location, startup options, etc. Battle Eye, as the name suggests, is used to configure Battle Eye settings.
🔵 Note: This separation is superficial and is only used to organize the variables. When setting environment variables this separation does not need to be taken into consideration.
| Variable | Default | Description |
|---|---|---|
| STEAM_BINARY_PATH | /usr/games/steamcmd | Path to the steamcmd binary |
| APP_ID | 223350 | The Steam App ID for DayZ Server |
| PORT | 2302 | The (game) port the server will run on |
| PROFILES_PATH | /profiles | The path to the profiles directory |
| CONFIG_PATH | ${SERVER_DIRECTORY}/serverDZ.generated.cfg |
The path to the server configuration file. Changing this will result in all Server environment variables being ignored. |
| CPU_COUNT | cpus().length/2 (or half of the CPUs available) | The number of cores the server will use |
| MOD_LIST | A comma separated list of mod IDs to download and enable on the server | |
| MOD_APP_ID | 221100 | The Steam App ID the workshop items (AKA: the mods) are associated with |
| MODS_PATH | ${SERVER_DIRECTORY}/steamapps/workshop/content/${MOD_APP_ID} |
The path to where the downloaded workshop items can be found |
| CLEAN_MODS | false | On start, the server will uninstall and delete all mods not found in MOD_LIST. (Uninstallation is limited to reversing any actions performed by the server to install the mods, any other configuration (whether applied manually or by the mod itself) will remain) |
| STEAM_USERNAME | anonymous | The username for the Steam account to use for downloading the server and mods |
| STEAM_PASSWORD | The password for the Steam account to use for downloading the server and mods | |
| STEAM_GUARD_CODE | The Steam Guard code for the Steam account to use for downloading the server and mods | |
| SERVER_DIRECTORY | /dayz | The directory to install the server and mods into |
| DO_LOGS | false | adds -dologs to the server start command |
| ADMIN_LOG | false | adds -adminlog to the server start command |
| NET_LOG | false | adds -netlog to the server start command |
| FREEZE_CHECK | false | adds -freezecheck to the server start command |
| BE_PATH | ${SERVER_DIRECTORY}/battleye |
The path to the BattlEye directory |
| EXTRA_STARTUP_ARGS | Any additional arguments to pass to the server start command | |
| SKIP_UPDATE | false | Skips the server update process |
| SKIP_MOD_UPDATE | false | Skips the mod update process |
| START_DAYZ_SERVER | true | Starts DayZServer. Set to false if you, for example, only want to update the server and mods. |
| MAPS_PATH | ${SERVER_DIRECTORY}/maps |
The path to download maps to. |
| MAP_URL | The URL to download the map from. | |
| COPY_MISSION | false | When set to true, will copy the mission directory (specified by MISSION_PATH) to the mpmissions directory, instead of symlinking it. |
| MISSION_PATH | ${SERVER_DIRECTORY}/mpmissions/dayzOffline.chernarusplus |
The path to the mission directory to symlink into mpmissions. For custom maps this would usually be /dayz/maps/<mission> and would not be a directory within the mpmissions directory. |
| UPDATE_MAP | false | When set to true, will overwrite any existing map when the server starts. Warning: this may cause data loss. |
| EXIT_WITH_CHILD | true | When not set to false, the server will exit when the child process (DayZServer) exits. |
Most of the server env. variables are the UPPERSNAKE_CASE version of camelCase configuration options found in the serverDZ.cfg/server.cfg file. However, this is not always the _case (e.g. SERVER_NAME, ADMIN_PASSWORD). For more information on what each variable does, refer to the official DayZ configuration documentation.
