WATCHDOG_TIME: amount of time between checking server heartbeat.

Game options specified will launch a dedicated server visible on steam clients. The game server will check for updates on boot and reboot.

Initial Startup

7 Days needs to be started twice to generate the basic files in the correct locations for server configuration.

Start 7 Days server to generate configuration files.

docker-compose up -d 7days

Note

Wait until you see the message:

Using config file: /data/server/serverconfig.xml

This means that the server has started.

Stop 7 Days server and configure it.

docker-compose stop 7days

0644 7days 7days /data/server/serverconfig.xml

# Uncomment this line and redirect saves to container data store.
<property name="SaveGameFolder" value="/data/saves" />

Start 7 Days server to generate server admin files.

docker-compose up -d 7days

Note

Wait until you see the message:

Using config file: /data/server/serverconfig.xml

This means that the server has started.

Stop 7 Days server and configure it.

docker-compose stop 7days

Disable Insecure 7 Day Services

Disable these insecure services that 7 Days uses, and set long random passwords.
