This is an unofficial implementation of a dedicated server for Satisfactory.

This guide assumes the following:

• You have intermediate knowledge of Linux and Docker
• You have Satisfactory on Steam (Epic may be supported in the future)

You'll need to generate a new save (or grab an existing save) for the server to use. You can usually find your save files located in C:\Users\Your User\AppData\Local\FactoryGame\Saved\SaveGames\common\your-world.sav. Once you've located this file, put it into /config/savefiles/ and make sure that its file extension is .sav.

You'll need to bind a local directory to the Docker container's /config directory. This directory will hold the following directories:

• /gamefiles - this is for the game's files. They're stored outside of the container to avoid needing to redownload 15GB+ every time you want to rebuild the container.
• /savefilebackups - the server will automatically backup your saves every 6 hours into this directory.
• /savefiles - this is for the game's saves. They're copied into the container on start, and the saves will be copied back to the host every 30 minutes.
• /steam - this retains your Steam credentials, simplifying the update process.

You'll also need to provide your Steam username, password, and Steam Guard code when you first run the container. To get your Steam Guard code, start the login process using the steamcmd Docker image, which will send you an email with the code in (you don't need to finish the login process in that image, you can just press CTRL + C to cancel it). You can run that image like this:

docker run -it steamcmd/steamcmd +login Your-Steam-Username Your-Steam-Password

With your credentials in hand, as well as the absolute path to your config directory, run the Satisfactory server image like this:

docker run -d --name=satisfactory-server -h satisfactory-server -e STEAMUSER=Your-Steam-Username -e STEAMPWD=Your-Steam-Password -e STEAMCODE=Your-Steam-Code -e MAXBACKUPS=10 -v /path/to/config:/config -p 7777:7777/udp wolveix/satisfactory-server:latest

If you're using Docker Compose:

version: '3'
services:
    satisfactory-server:
        container_name: 'satisfactory-server'
        hostname: 'satisfactory-server'
        image: 'wolveix/satisfactory-server:latest'
        environment:
            - STEAMUSER=Your-Steam-Username
            - STEAMPWD=Your-Steam-Password
            - STEAMCODE=Your-Steam-Code
            - MAXBACKUPS=10
            - SKIP_UPDATE=true # Only possible when downloaded already. 
            - MOD_IDS=5yGWmmB8KL2Zq8:93bH5XDMFXs5fe #Smart! at latest version
        ports:
            - '7777:7777/udp'
        volumes:
            - '/path/to/config:/config'
        restart: unless-stopped

You won't need to re-obtain your Steam Guard code after the initial creation.

If you want to run a server for the Experimental version of the game, simply add a STEAMBETA=true environment variable.

To join the dedicated server:

• Press WIN + R
• Enter %localappdata%/FactoryGame/Saved/Config/WindowsNoEditor
• Open Input.ini in notepad
• Paste the following at the end of the file:

[/script/engine.inputsettings]
ConsoleKey=F6
ConsoleKeys=F6

Open Satisfactory, press F6 on the main menu and you should see a console appear. Run:

Open your.server.ip

It should start loading into the world almost instantly. If it doesn't, then it's probably going to timeout after 20 seconds.

The Satisfactory Wiki recommends a few config tweaks to really get the best out of multiplayer. These changes are already applied to the server, but they need to be applied to your local config too:

• Press WIN + R
• Enter %localappdata%/FactoryGame/Saved/Config/WindowsNoEditor
• Copy the config data from the wiki into the respective files
• Right-click each of the 3 config files (Engine.ini, Game.ini, Scalability.ini)
• Go to Properties > tick Read-only under the attributes

• The server is public, meaning that anyone with your server IP or hostname will be able to join your world.
• The server log will show various errors; most of which can be safely ignored. As long as the container continues to run and your log looks similar to the example log, the server should be functioning just fine: example log

This wouldn't have been possible without the following repos:

• CM2Walki/CSGO
• zig-for/satisfactory-docker
