RabbitMQ

RabbitMQ is a message broker for asynchronous communication between services.
Producers publish messages to queues/exchanges, and consumers receive/process them.

How RabbitMQ works

flowchart LR
    Producer([Producer]) -->|:5672| Exchange[Exchange]
    Exchange --> Queue[Queue]
    Queue --> Consumer([Consumer])
    Admin([Admin]) -->|:15672| UI[Management UI]

Loading

1. Producers publish messages to RabbitMQ.
2. RabbitMQ routes messages to queues based on exchange/binding rules.
3. Consumers subscribe to queues and process messages.
4. The management UI lets you inspect queues, exchanges, connections, and rates.

Stack details in this repo

• Image: rabbitmq:3-management
• Container name: rabbitmq
• Hostname: rabbitmq
• AMQP port: 5672
• Management UI: http://<host-ip>:15672

Environment variables

Set via .env (copy from .env.example):

• RABBITMQ_DEFAULT_USER (default example: admin)
• RABBITMQ_DEFAULT_PASS (default example: admin)

How to run

From the repository root:

cd rabbitmq
cp .env.example .env
docker compose up -d

Open:

• RabbitMQ UI: http://localhost:15672

Login using values from .env.

Useful commands:

docker compose ps
docker compose logs -f
docker compose restart
docker compose down

Use it effectively

• Create queues/exchanges from the management UI for quick testing.
• Use the example folder scripts as a basic producer/consumer demo.
• Monitor unacked and ready message counts to detect backlogs.

Notes

• Change default credentials before exposing RabbitMQ externally.
• Port 5672 should be reachable by app containers/services that publish or consume.
