Runtime contract
- Game traffic:
34197/UDP - Native RCON:
27015/TCP - Persistent data:
/factorio - Small servers generally need 1–2 GB RAM.
Console commands
Use the dashboard console for supported commands: /players, /save, /kick, /ban, and /whitelist. Player telemetry is derived from /players; unavailable RCON remains unknown.
Saves and mods
The first boot creates a save using GENERATE_NEW_SAVE=true and SAVE_NAME. Saves, configuration, and mods remain under /factorio. Install mods from the Factorio Mod Portal and keep mod versions aligned with the server version.
