7 Days to Die server that runs inside a Docker container

Docker Automated build Docker build status Docker Pulls Docker stars

This image will always install/update to the latest steamcmd and 7 Days to Die server, all you have to do to update your server is to redeploy the container.

Also note that the entire /steamcmd/7dtd can be mounted on the host system, which would avoid having to reinstall the game when updating or recreating the container.

How to run the server

  1. First time only: Rename .env-sample to .env # This is where you'll hold information such as server & telnet password.
  2. Optionally set the SEVEN_DAYS_TO_DIE_SERVER_STARTUP_ARGUMENTS environment variable to match your preferred server arguments (defaults are set to "-quit -batchmode -nographics -dedicated")
  3. Optionally set the SEVEN_DAYS_TO_DIE_CONFIG_FILE environment variable to a different configuration file (default is /app/.local/share/7DaysToDie/serverconfig.xml)
  4. Mount /steamcmd/7dtd and /app/.local/share/7DaysToDie somewhere on the host to keep your data safe (first path has the server files, while the second path has the config and save files)
  5. Run the server once to generate the default configuration file, then optionally edit it at /app/.local/share/7DaysToDie/serverconfig.xml to your liking

Make sure that the 7D2D serverconfig.xml file has the same server and telnet password as the one you've set in .env file

.ev serverconfig.xml
SEVEN_DAYS_TO_DIE_SERVER_PASSWORD=testPassword <property name="ServerPassword" value="testPassword"/>

SEVEN_DAYS_TO_DIE_START_MODE. This determines if the server should update and then start (mode 0), only update (mode 1) or only start (mode 2)) The default value is "0".

Argument Value Description
SEVEN_DAYS_TO_DIE_START_MODE 0 (Default) server should update and then start
SEVEN_DAYS_TO_DIE_START_MODE 1 server should only update
SEVEN_DAYS_TO_DIE_START_MODE 2 server should only start

You should also enable telnet and modify the SEVEN_DAYS_TO_DIE_TELNET_PORT and SEVEN_DAYS_TO_DIE_TELNET_PASSWORD environment variables accordingly, so the container can properly send the shutdown command to the server when the proper signal has been received (it uses telnet for this).

SEVEN_DAYS_TO_DIE_UPDATE_CHECKING is "0" Fully automatic updates(default = disabled). Once a server update hits Steam, it'll restart the server and trigger the automatic update. You can enable this by setting SEVEN_DAYS_TO_DIE_UPDATE_CHECKING to "1".
You can also use a different branch via environment variables. For example, to install the latest experimental version, you would simply set SEVEN_DAYS_TO_DIE_BRANCH to latest_experimental (this is set to public by default).

If using Docker for Windows and the File System passthrough option, make sure to add the git repo drive letter as a shared drive through the Docker GUI.

NOTES:

  • telnet password seems to fail if other than alphanumeric (a-A, z-Z, 0-9)
  • Run docker-compose config to check if you properly set things up in docker-compose file
