⁠What is Mordhau?

MORDHAU is a multiplayer medieval slasher. Create your mercenary and fight in brutal battles where you will experience fast paced combat, castle sieges, cavalry charges, and more.
This Docker image contains the dedicated server of the game.

⁠How to use this image

⁠Hosting a simple game server

Running on the host interface (recommended):

$ docker run -d --net=host --name=mordhau-dedicated cm2network/mordhau

Running using a bind mount for data persistence on container recreation:

$ mkdir -p $(pwd)/mordhau-data
$ chmod 777 $(pwd)/mordhau-data # Makes sure the directory is writeable by the unprivileged container user
$ docker run -d --net=host -v $(pwd)/mordhau-data:/home/steam/mordhau-dedicated/ --name=mordhau-dedicated cm2network/mordhau

Running multiple instances (iterate SERVER_PORT, SERVER_QUERYPORT and SERVER_BEACONPORT):

$ docker run -d --net=host -e SERVER_PORT=7778 -e SERVER_QUERYPORT=27016 -e SERVER_BEACONPORT=15001 --name=mordhau-dedicated2 cm2network/mordhau

It's also recommended using "--cpuset-cpus=" to limit the game server to a specific core & thread.
The container will automatically update the game on startup, so if there is a game update just restart the container.
