Quickly set up and test the Bully Algorithm for leader election in distributed systems using Docker Compose. The provided Docker Compose file launches four nodes, allowing you to easily observe the cluster behavior.

Usage: Build and run Docker Compose:

docker-compose up --build Test the cluster behavior by killing nodes with Docker commands.

To add new nodes, update the hardcoded node addresses in the source code:

var nodeAddressByID = map[string]string{
    "node-01": "node-01:6001",
    "node-02": "node-02:6002",
    "node-03": "node-03:6003",
    "node-04": "node-04:6004",
}

This repository focuses on demonstrating leader election using the Bully Algorithm without implementing a full-fledged service discovery mechanism.

You can still execute this project without using Docker.

First, change the Node IPs. For example

var nodeAddressByID = map[string]string{
	"node-01": "node-01:6001", <--- change here to localhost:6001
	"node-02": "node-02:6002", <--- change here to localhost:6002
	"node-03": "node-03:6003", <--- change here to localhost:6003
	"node-04": "node-04:6004", <--- change here to localhost:6004
}

Second, you can set which node you want to run in Program arguments like

go run . node-02
