Space Engineers on Linux

Docker container for running a Space Engineers server There is no public prebuilt container image because of copyright restrictions These instructions will guide you to configure the environment and build your own container

Setup

• Create the required directory structure.

mkdir -p space-engineers/{docker,data,steam}
mkdir -p space-engineers/data/Space\ Engineers/{Mods,Saves}

• Clone this repository into the home directory of the new user account.

git clone https://github.com/ChipWolf/se-server.git space-engineers/docker

• Obtain a copy of the most current DedicatedServer.zip and place it in ~/games/space-engineers/data. You may use this method below.

docker run --rm -it -v $(pwd)/space-engineers/steam:/data wilkesystems/steamcmd

# the following 4 commands are for the steamcmd terminal
login anonymous
force_install_dir /data
app_update 298740 validate
quit

• At this stage we need to patch a few .dlls to fix an issue with mods not downloading, thanks to Thomas_Jefferson from the Keen Software House forum for this one.

cd space-engineers/steam
zip -r ../data/DedicatedServer.zip
cd ../..
sudo chown -R 256:256 space-engineers

• Upload your SpaceEngineers-Dedicated.cfg and place it in ~/games/space-engineers/data/Space Engineers. Use the one in this repository and edit it to your liking if you do not already have one.

• Build the image! (This will take a while)

space-engineers/docker/build.sh

Starting the server

docker run -it -p 27016:27016/udp -v $(pwd)/games/space-engineers/data:/host --rm --name space-engineers saiban/space-engineers

---

Additional notes

Running Space Engineers this way requires a helper program called sigmap which was developed for this use specifically. It is cloned and built by the Dockerfile and should not add any additional overhead. Because Space Engineers ignores SIGTERM which is sent by Docker to shut down the service, sigmap catches that signal and forwards SIGINT to Space Engineers.

See here for more information.
