This guide covers the kerbalspaceprogramserver module in AlphaGSM.

kerbalspaceprogramserver 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

Docker for the validated Linux runtime path
Python packages from requirements.txt

Quick Start

Create the server:

alphagsm mykerbalsp create kerbalspaceprogramserver

Run setup:

alphagsm mykerbalsp setup

Start it:

alphagsm mykerbalsp start

Check it:

alphagsm mykerbalsp status

Stop it:

alphagsm mykerbalsp stop

Setup Details

Setup configures:

the game port (default 8800)
the install directory
downloads and extracts the Linux LunaMultiplayer server archive
prepares the first-run XML config files AlphaGSM manages before start

Useful Commands

alphagsm mykerbalsp update
alphagsm mykerbalsp backup

Notes

Module name: kerbalspaceprogramserver
Default port: 8800

Server variables

After create kerbalspaceprogramserver, inspect or change these with set:

alphagsm myserver set --list
alphagsm myserver set KEY --describe
alphagsm myserver set KEY VALUE

This module does not declare schema-backed keys. set --list after create is still the live source of truth.

Developer Notes

Run File

Executable: LMPServer-linux-x64/Server
Location: <install_dir>/LMPServer-linux-x64/Server
Runtime: Native Linux, validated through the shared steamcmd-linux Docker runtime
Health surface: generic udp on the managed main game port

Server Configuration

Config files:
- <install_dir>/LMPServer-linux-x64/Config/ConnectionSettings.xml
- <install_dir>/LMPServer-linux-x64/Config/GeneralSettings.xml
AlphaGSM creates these files on first launch when the upstream archive has not generated them yet, then keeps the managed port, server name, and max players in sync before start.
