Jokes App

This repository demonstrates the usage of RabbitMQ server with Go application. The application subscribe to a queue to receive request and then publishes the response on another queue.

The application calls the jokes api and use the result as response to send to publish queue.

Async API

The asyncapi.yaml file contains the definitions of the api this application uses.

Run the application

• First build the image with docker-compose using command docker-compose build in root of the repo
• Next start both RabbitMQ and the Joke application with docker-compose: docker-compose up or docker compose up -d
• RabbitMQ is available at localhost now from your machine. To access it in other docker container you can add the network created by docker-compose (rabbitmq-go_default) to the container's network list.
• Now the application is listening to the joke-subscribe-queue which is bound to exchange test.go.example with routing key joke-request.
• It will respond with a joke to the queue joke-publish-queue which is bound to the exchange test.go.example with routing key joke-response

RabbitMQ management UI

To access the management UI of RabbitMQ you can go to the url: http://localhost:15672/ and login with default admin credentials: username: guest and password: guest

Here you can see the administration options and the list of exchanges, queues and access the messages in the queue. You can also add new messages to the queues as well.
