⁠What is Holdfast: Nations At War ?

Fight on multiple fronts in Holdfast: Nations At War - A competitive multiplayer first and third person shooter set during the great Napoleonic Era. Charge into battle with over 150 players per server!

⁠How to use this image

⁠Hosting a simple game server

Running on the host interface (recommended):

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

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

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

Running multiple instances:

$ docker run -d --net=host --name=holdfastnaw-dedicated2 cm2network/holdfastnaw

It's also recommended to use "--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.

⁠Image Variants:

⁠holdfastnaw:latest, holdfastnaw:on-demand

⁠holdfastnaw:full

Specialized version of holdfastnaw:on-demand. The game server files are pre-packaged within this image, trading storage for faster start-up times. Note: The game server files are still updated on container start. Ideal for container orchestration tools (Kubernetes, Docker Swarm, etc.).
