Configuration

Custom config

A custom configuration can be loaded by mounting the file to: /data/openttd.cfg

Available options are listed in the official wiki and github.

Load latest autosave

If the environment variable LOAD_AUTOSAVE is set, the latest autosave present in /data/save/autosave/ will be loaded.

Load template save

A template save file can be loaded by mounting the file to: /data/save/template.sav

The file will be ignored if LOAD_AUTOSAVE is set and an autosave file is present in /data/save/autosave/.

Custom user or group id

A custom user or group id can be defined by setting the environment variable PUID or PGID, e.g. PUID=2000 or PGID=3000.

Online content

To download online content in a running container, use the content command:

content update
content state ITL Houses
content select 54540301
content download

For online content to be loaded from persistent storage, make sure the content file is:

Present in the mounted volume, e.g.

/data/content_download/newgrf/54540301-ITL_Houses-2.1.tar

And configured in the /data/openttd.cfg config file, e.g.

[newgrf]
54540301|F7CDD4F730E4F3EE87100CE42E5070AE|itl_houses-2.1/itl_houses.grf = 0 0 0

Ports

If no port mapping is configured for the container, a server with server_game_type = public will still register with the Game Coordinator and attempt to use Connection type: Behind NAT to establish connections with clients.
