For operating a dedicated server in Docker in order to use it under Linux. The container uses Wine to run the server under Linux.

1. Create a new empty directory in any location with enough storage space.
2. Create a file named docker-compose.yml and copy the content of docker-compose.yml.example into it.
3. In the docker-compose.yml file, the environment variables ServerPassword and SteamServerName should be adjusted.
4. Setup and start via docker-compose by running the command docker-compose up -d.
   • This will run the server in the background and autostart it whenever the docker daemon starts. If you do not want this, remove -d from the command above.
   • This will download the Dedicated Server binaries and game files to the gamefiles directory.
   • Persistent save file data will be written to the data directory.

There are two ways to update the game server:

1. By setting the AutoUpdate environment variable to true. This checks for updates every time the container is started.
2. By deleting the gamefiles directory while the server is turned off.

Sometimes, changes to this container image are necessary. To apply these:

1. Merge the content of docker-compose.yml with any changes made from docker-compose.yml.example.
2. Run docker-compose pull to download an updated version of the container image.

An example configuration for docker-compose can be found in the docker-compose.yml file. In addition to the default settings, which can be set via the environment variables, further arguments can be specified via the AdditionalArgs environment variable.

Possible launch parameters and further information on the dedicated servers for Abiotic Factor can be found here.
