DayZDockerServer

A Linux DayZ server in a Docker container. The main script's functionality is derived from this project. That functionality is described here. The goal is to reproduce all that functionality and add even more while keeping it all in Docker.

Caveat Emptor

As of DayZ release 1.15, a Linux DayZ server was made available in Dayz Experimental. This has not been officially released, so this will only run a DayZ Experimental server at the moment. Only the DayZ Experimental client will be able to connect to it.

This process will create a docker volume for the unprivileged user's home directory, which stores the DayZ server files. This volume can get quite large. It will require at least 2G of disk space for the default install. Much more with mods.

Configure and Build

Edit files/serverDZ.cfg and set the values of any variables there. See the documentation:

hostname = "Something other than Server Name";   // Server name

Optionally edit files/beserver_x64.cfg and set the RCON password (leaving the other lines intact):

RConPassword h4CKm3

If the above step is not performed, a random RCON password will be generated and output to the log on the first run. It can also be obtained and reset. See Manage.

Build the Docker image:

docker-compose build

Steam Integration

SteamDMD is used to manage Steam downloads. A vanilla DayZ server can be installed with the anonymous Steam user, but most mods cannot. If the goal is to add mods, a real Steam login must be used. Login:

docker-compose run --rm main dayzserver login

Follow the prompts. Hit enter to accept the default, which is to use the anonymous user, otherwise use your real username and keep following the prompts to add your password and Steam Guard code. With Steam Guard enabled on the Steam account, entering the password will trigger the sending of an email with the code. This process will wait indefinitely until the code is entered.

The credentials will be managed by SteamCMD and stored in the docker volume. All subsequent SteamCMD commands will use the cached credentials. so this process does not need to be repeated unless the session expires or the docker volume is deleted.

Run the command again to manage the login. See Manage.

Run

Launch the container into the background:

docker-compose up -d main

Tail the log:

docker-compose logs -f main

Manage

The management commands many be run while the server is up. YMMV

RCON

Show the current Battle Eye configuration file (Derived from files/beserver_x64.cfg):

docker-compose run --rm main dayzserver rcon show

Reset the RCON password in the Battle Eye configuration file:

docker-compose run --rm main dayzserver rcon reset

Restart

Restarts the server. If it's not running, does nothing.

docker-compose run --rm main dayzserver restart

Stop

Stops the server. If it's not running, does nothing.

docker-compose run --rm main dayzserver stop

Update the DayZ server files

docker-compose run --rm main dayzserver update

Workshop

WIP

docker-compose run --rm main dayzserver workshop

TODO

• Makage -mod= command line
• RCON to the server. Send real time messages to players, such as restart announcements.
