Airtable integration

Backend for updating the shared airtable for the event.

Setup

Generate a secret and token pair with

node gentoken

and note down the output, the secret is used for the main server and the token for the remote game servers. Generate a TLS key and certificate pair with

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes -subj /CN=localhost -addext "subjectAltName=IP:192.0.2.4"

Modify the IP to be that of the Main server.

Main server

For the main server with the lobby create a .env file with the following content:

Is_lobby=true
Api_key=Airtable API key
Base_key=Airtable base id
Servers=Path to servers.json
secret=Secret generated by gentoken
key=key.pem
cert=cert.pem
port=1234
bind_ip=Leave blank unless you know what you're doing.

Create a servers.json file for the local servers, see last section for what it should contain. Then run the server with

node main

Remote Game Servers

For remote servers hosting extra Factorio game servers create a .env file with the following content.

Is_lobby=false
Api_key=Airtable API key
Base_key=Airtable base id
Servers=Path to servers.json
token=token generated by gentoken
url=WebSocket URL to connect to (e.g. wss://192.0.2.4:1234/)
cert=cert.pem

If you generated a self signed cert with openssl you need to copy the generated cert.pem certificate to the remote game servers and specify it in .env.

servers.json format

A JSON object where keys are ip:port the Factorio server and the value is an object containing dir, Rcon_pass, Rcon_port and is_lobby. See example below. For the main server there must be exactly one server with is_lobby set to true. For the remote game servers no server can be the lobby.

{
    "192.0.2.4:5001": {
        "dir": "/opt/factorio/lobby/script-output/mini_games/",
        "Rcon_pass": "rcon",
        "Rcon_port": 5101,
        "is_lobby": true
    },
    "192.0.2.4:5002": {
        "dir": "/opt/factorio/game1/script-output/mini_games/",
        "Rcon_pass": "rcon",
        "Rcon_port": 5102,
        "is_lobby": false
    }
}
