What is Factorio?

Factorio is a game in which you build and maintain factories.

You will be mining resources, researching technologies, building infrastructure, automating production and fighting enemies. Use your imagination to design your factory, combine simple elements into ingenious structures, apply management skills to keep it working and finally protect it from the creatures who don't really like you.

The game is very stable and optimized for building massive factories. You can create your own maps, write mods in Lua or play with friends via Multiplayer.

NOTE: This is only the server. The game is available at factorio.com and Steam.

Usage

Quick Start

Run the server to create the necessary folder structure and configuration files. For this example data is stored in /tmp/factorio.

docker run -d -P -v /tmp/factorio:/factorio --name factorio dtandersen/factorio

For those new to Docker, here is an explanation of the options:

• -d - Run as a daemon ("detached").
• -P - Expose all ports.
• -v - Mount /tmp/factorio on the local file system to /factorio in the container.
• --name - Name the container "factorio" (otherwise it has a funny random name).

Check the logs to see what happened:

docker logs factorio

Stop the server:

docker stop factorio

Now there's a server-settings.json file in the folder /tmp/factorio/config. Modify this to your liking and restart the server:

docker start factorio

Try to connect to the server. Check the logs if it isn't working.

Saves

A new map named _autosave1.zip is generated the first time the server is started. The map-gen-settings.json file in /tmp/factorio/config is used for the map settings. On subsequent runs the newest save is used.

To load an old save stop the server and run the command touch oldsave.zip. This resets the date. Then restart the server. Another option is to delete all saves except one.

To generate a new map stop the server, delete all of the saves and restart the server.

Mods

Copy mods into the mods folder and restart the server.

RCON

Set the RCON password in the rconpw file. A random password is generated if rconpw doesn't exist.

To change the password stop the server, modify rconpw, and restart the server.

To "disable" RCON don't expose port 27015, i.e. start the server with -p 34197:34197/udp instead of -P. RCON still runs, but nobody is able to connect to it.

Container Details

The philosophy is to keep it simple.

• The server should bootstrap itself.
• Prefer configuration files over environment variables.
• Use one volume for data.

Volumes

To keep things simple, the container uses a single volume mounted at /factorio. This volume stores configuration, mods, and saves.

factorio
|-- config
|   |-- map-gen-settings.json
|   |-- rconpw
|   `-- server-settings.json
|-- mods
|   `-- fancymod.zip
`-- saves
    `-- _autosave1.zip

Ports

• 34197/udp - Factorio clients (required).
• 27015/tcp - RCON (optional).

Troubleshooting

My server is listed in the server browser, but nobody can connect

Check the logs. If there is the line Own address is RIGHT IP:WRONG PORT, then this could be caused by the Docker proxy. If the the IP and port is correct it's probably a port forwarding or firewall issue instead.

By default, Docker routes traffic through a proxy. The proxy changes the source UDP port, so the wrong port is detected. See the forum post Incorrect port detected for docker hosted server for details.

To fix the incorrect port, start the Docker service with the --userland-proxy=false switch. Docker will route traffic with iptables rules instead of a proxy. Add the switch to the DOCKER_OPTS environment variable or ExecStart in the Docker systemd service definition. The specifics vary by operating system.
