Didstopia/7dtd-server

7 Days to Die server that runs inside a Docker container

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. Optionally set the SEVEN_DAYS_TO_DIE_SERVER_STARTUP_ARGUMENTS environment variable to match your preferred server arguments (defaults are set to "-logfile /dev/stdout -quit -batchmode -nographics -dedicated", note how we're logging to stdout)
2. Optionally set the SEVEN_DAYS_TO_DIE_CONFIG_FILE environment variable to a different configuration file (default is /app/.local/share/7DaysToDie/serverconfig.xml)
3. 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)
4. Run the server once to generate the default configuration file, then optionally edit it at /app/.local/share/7DaysToDie/serverconfig.xml to your liking

You can control the startup mode by using 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".

Note that you should also enable telnet and optionally 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).

One additional feature you can enable is fully automatic updates, meaning that 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.
