Basic rabbitmq process

Quick demo of rabbitmq with existing tools just to see it in action.

1. Run a rabbitmq container so you won’t have to install it on the local machine: docker run -it --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:4-management
2. Download rabbmitmqadmin from your local instance: wget http://localhost:15672/cli/rabbitmqadmin
3. Make the tool executable: chmod +x ./rabbitmqadmin
4. Check the queue

./rabbitmqadmin list queues
No items

5. Declare a queue

 ./rabbitmqadmin declare queue name=greetings durable=true
queue declared

6. Publish a message

./rabbitmqadmin publish exchange=amq.default routing_key=greetings payload="Hello, World"
Message published

7. Check the queue again

./rabbitmqadmin list queues
+-----------+----------+
|   name    | messages |
+-----------+----------+
| greetings | 1        |
+-----------+----------+

8. Get the message

./rabbitmqadmin get queue=greetings
