Double Action: Boogaloo Server (Docker)

This repository provides a Dockerized Double Action: Boogaloo dedicated server. The game content in the Double Action Dedicated Server (Steam app 317800) ships only Windows server binaries (dab/bin/server.dll), so the image runs the Windows srcds.exe under Wine. The image builds on lancommander/wine. It supports file overlaying using OverlayFS.

---

Features

• Installs and updates the Double Action Dedicated Server (Steam app 317800, Windows depot) with SteamCMD, anonymously
• Common server settings are environment variables, applied after the stock server.cfg so they always take effect
• The server console (da_info/console.log) is streamed to docker logs
• Supports file overlaying using OverlayFS (no file copying required)

Game Files

SteamCMD downloads app 317800 with the Windows platform forced (about 2.3 GB) into config/Server/ on every start. Set STEAM_APP_UPDATE=false to skip the update once it is installed.

The app's engine depot is from 2014, but its game content depot (dab/) is shared with the game and is current (dab/steam.inf holds the version, e.g. PatchVersion=1.6.0.0). Clients must run the same version as the server.
