Factorio

A Docker image for the Factorio dedicated server.

Versions

See tags on Quay for options. If you don't see a version after 0.14.4 that you are looking for, file an issue and or a pull request.

Usage

The simplest example runs Factorio with default settings. We also mount a volume so that your saves will be retained:

docker run -d \
  -v [PATH]:/opt/factorio/saves \
  -p [PORT]:34197/udp \
  quay.io/games_on_k8s/factorio:0.14.14

• Where [PATH] is a folder where you'll put your saves. If there already is a save in it with the string "save", that one will be taken by default, otherwise, a new one will be made.
• Where [PORT] is the port number to listen for client connections on.

Environment Variable Reference

This Docker image uses environment variables to configure the Factorio server. The gen_config.py dumps a server-settings.json before the server starts. Here are the possible values (bolded values are the ones you'll generally always want to change):

Troubleshooting

Authorization Error

If your container exits with the following error:

Info HttpSharedState.cpp:83: Status code: 401
Info AuthServerConnector.cpp:40: Error in communication with auth server: code(401) message({
  "message": "Username and password don't match",
  "status": 401
})
Info AuthServerConnector.cpp:68: Auth server authorization error (Username and password don't match)
Error Util.cpp:57: Unknown error

Check supplied Username and Password for mistakes.

Cutting a new release

For maintainers with write access to Quay, here's how to cut a new release:

./make_release.sh 0.14.15

This will download the correct archive, build a Docker image, and run it locally. Test against the built image, then CTRL+C out of the server. The script will prompt you through the rest of the release process.

NOTE: If the env vars have changed in the release compared to what is currently in the repo, you'll need to adjust gen_config.py and this README.md accordingly.

Once the Docker image is pushed, make sure any changes to this repo are committed then create a new tag matching the version number of the release.

git commit -am "Made some changes. Woohoo."
git push
git tag 0.14.15 && git push --tags
```
