This guide covers the armarserver module in AlphaGSM.

armarserver is currently listed as PASSED in the checked-in support tracker on the documented Ubuntu 24.04 Linux baseline. The current GitHub integration lane still exercises both process and Docker runtime selection around this SteamCMD-backed lifecycle, but the checked-in integration test still carries an upstream install skip note and should be revalidated before treating that tracker row as freshly proven.

Requirements

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

Quick Start

Create the server:

alphagsm myarmarser create armarserver

Run setup:

alphagsm myarmarser stop

Setup Details

Setup configures:

the game port (default 2001)
the install directory
SteamCMD downloads the server files

Structured Settings

AlphaGSM exposes the JSON-backed settings through set:
