This guide covers the bmdmserver module in AlphaGSM.

bmdmserver is currently PASSED on the documented Ubuntu 24.04 Linux baseline. The current GitHub integration lane still exercises both process and Docker runtime selection, and the validated Linux lifecycle stays aligned across both backends while local runs remain process-backed by default unless you opt into the Docker backend.

Requirements

  • screen
  • SteamCMD runtime libraries (lib32gcc-s1, lib32stdc++6)
  • Python packages from requirements.txt

Quick Start

Create the server:

alphagsm mybmdmserv create bmdmserver

Run setup:

alphagsm mybmdmserv setup

Start it:

alphagsm mybmdmserv start

Check it:

alphagsm mybmdmserv status

Stop it:

alphagsm mybmdmserv stop

Setup Details

Setup configures:

  • the game port (default 27015)
  • the install directory
  • the executable name
  • SteamCMD downloads the server files
  • default configuration and backup settings

Useful Commands

alphagsm mybmdmserv update
alphagsm mybmdmserv backup

Notes

  • Module name: bmdmserver
  • Default port: 27015
  • Process and Docker integration readiness use AlphaGSM info --json protocol a2s; Docker does not depend on a host screen log.

Server variables

After create bmdmserver, inspect or change these with set:

alphagsm myserver set --list
alphagsm myserver set KEY --describe
alphagsm myserver set KEY VALUE
Key Aliases Type What it does
map gamemap, startmap, level, worldname string The currently selected map or level. Example: dm_bounce.
maxplayers users integer Maximum number of player slots. Example: 16.
port gameport integer The primary game port. Example: 27015.
rconpassword rconpass, querypassword, query_administrator_password string Remote console password for administrative access. Stored as a secret.
servername hostname, name string The server's public name shown to players. Example: AlphaGSM Black Mesa: Deathmatch.
