Call of Duty Dedicated Server (Docker)

This repository provides a Dockerized Call of Duty dedicated server suitable for running multiplayer Call of Duty servers in a clean, reproducible way.
The image is designed for headless operation, supports bind-mounted mods and configuration, and handles legacy runtime dependencies required by Call of Duty.

---

Features

• Runs the Call of Duty dedicated server (cod_lnxded)
• Optionally downloads and extracts mod archives from URLs at startup
• Automated build & push via GitHub Actions

Docker Compose Example

services:
  callofduty:
    image: lancommander/callofduty:latest
    container_name: callofduty-server

    # Call of Duty uses UDP
    ports:
      - "28960:28960/udp"

    # Bind mounts so files appear on the host
    volumes:
      - ./config:/config

    environment:
      # Optional: download mods/maps at startup
      # EXTRA_MOD_URLS: >
      #   https://example.com/maps.zip,
      #   https://example.com/gameplay.pk3

      # Optional overrides
      # SERVER_ARGS: '+set dedicated 2 +set sv_allowDownload 1 +set sv_dlURL \"\" +set com_hunkmegs 64'

    # Ensure container restarts if the server crashes or host reboots
    restart: unless-stopped

Directory Layout (Host)

.
└── config/
    ├── Server/            # Base JK2MV install
    │   └── main/          # Call of Duty game files base directory
    ├── Overlay/           # Files to overlay on game directory (optional)
    │   └── main/          # Call of Duty overlay directory
    │       ├── maps/      # Custom maps
    │       └── ...        # Any other files you want to overlay
    ├── Merged/            # Overlayfs merged view (auto-created)
    ├── .overlay-work/     # Overlayfs work directory (auto-created)
    ├── Scripts/
        └── Hooks/         # Script files in this directory get automatically executed if registered to a hook

Both directories must be writable by Docker.

Game Files

You will need to copy the pak*.pk3 files from your retail copy of Call of Duty into the /config/Server/base directory. The server will not run without these files.

---

Configuration

An autoexec.cfg file can also be created for adjusting server settings. Example:

////////////////////////////////////////////////////////////
