Creating a Docker image

OpenMoHAA dedicated server can run inside a container.

Preparing files

In the root of the project repository, you'll find a folder named docker. Copy your MOH:AA directory inside docker/server/full/game. The directory structure should look like this:

[docker/server/full/game]
├── [main]
│   └── Pak*.pk3
├── [mainta]
│   └── pak*.pk3
├── [maintt]
│   └── pak*.pk3
└── [home]
    ├── [main]
    │   └── Custom PK3s go here
    ├── [mainta]
    │   └── Custom PK3s go here
    └── [maintt]
        └── Custom PK3s go here

You can place custom files such as the server.cfg file, inside docker/server/full/game/home/main.

File locations inside the container

• Game files are located in /usr/local/share/mohaa.
• Custom content is located in /usr/local/share/mohaa/home.

Building the image

To build the base and full Docker images, use the following commands:

docker build -t openmohaa/base docker/server/base
docker build -t openmohaa/full docker/server/full

Running

To run the Docker container, use:

docker run -p 12203:12203 -p 12300:12300 openmohaa/full

💡 You can also use a Docker Compose file for easier management. Check out the docker/server/docker-compose-example.yaml file for an example.

Environment variables

• GAME_PORT: Specifies the game port to use (default: 12203). The container and the host port must match, as Gamespy sends the game port to use.
• GAMESPY_PORT: Specifies the Gamespy port to use (default: 12300). The container and the host port must match because Gamespy sends this port to the master server.

(Optional) Mounting volumes for settings

If you want to modify the server.cfg file without rebuilding the container, you can mount a folder for configuration files. Here's how:

1. Inside docker/server, create a config/settings folder.
2. Place your server.cfg file inside config/settings.
3. Run the container with the following command:

docker run -p 12203:12203 -p 12300:12300 -v config/settings:/usr/local/share/mohaa/home/main/settings openmohaa/full.

This will mount your settings folder directly into the container, allowing server.cfg to be edited without needing to rebuild the image.
