Jedi Knight II: Jedi Outcast Dedicated Server (Docker)

This repository provides a Dockerized Jedi Knight II: Jedi Outcast dedicated server via JK2MV suitable for running multiplayer Jedi Knight II: Jedi Outcast 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 Jedi Knight II: Jedi Outcast.

---

Features

• Runs the Jedi Knight II: Jedi Outcast dedicated server (jk2mvded)
• Optionally downloads and extracts mod archives from URLs at startup
• Automated build & push via GitHub Actions

Docker Compose Example

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

    # Jedi Knight II: Jedi Outcast uses UDP
    ports:
      - "27960:27960/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

└── config/
    ├── Server/            # Base JK2MV install
    │   └── base/          # Jedi Knight II: Jedi Outcast game files base directory
    ├── Overlay/           # Files to overlay on game directory (optional)

Both directories must be writable by Docker.

Game Files

You will need to copy the pak*.pk3 files from your retail copy of Jedi Knight II: Jedi Outcast 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:
