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

This is the defacto image. A bare-minimum Holdfast: Nations At War dedicated server containing no 3rd party plugins. The game server files are downloaded (or updated) on container start, increasing start-up time. Ideal for static hosting in volumes or bind-mounts.

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.).
