Message server

Running

Starting servers

Server ID (SERVER_ID) and remote servers (SERVERS) are provided as environment variables along with shared auth key (AUTH_KEY).

Server 1

SERVER_ID=1 SERVERS="2:localhost:4001" PORT=4000 mix run --no-halt

Server 2

SERVER_ID=2 SERVERS="1:localhost:4000" PORT=4001 mix run --no-halt

Sending messages

From Server 1

curl -X POST http://localhost:4000/api/messages -H "Content-Type: application/json" -d '{"from": "1-bender", "to": "1-zoidberg", "message": "Dreams are where elves and gnomes live!"}'

curl -X POST http://localhost:4000/api/messages -H "Content-Type: application/json" -d '{"from": "1-bender", "to": "2-nibbler", "message": "Bite my shiny metal ass!"}'

From Server 2

curl -X POST http://localhost:4001/api/messages -H "Content-Type: application/json" -d '{"from": "2-nibbler", "to": "1-bender", "message": "I am Nibbler, agent of the Nibblonian fleet."}'

Security

This application uses a shared auth key (AUTH_KEY) to authenticate requests between servers. The key is provided as an environment variable and must be the same on all servers.

Next steps

HTTPS with client certificates should be implemented to ensure secure communication between servers and prevent unauthorized access and possible man-in-the-middle attacks.
