Simple demonstration of RabbitMQ using Python and Docker

This is an application template which uses Python, RabbitMq, pipenv and Docker.

What is RabbitMQ

RabbitMQ is the most widely deployed open source message broker.

RabbitMQ is lightweight and easy to deploy on premises and in the cloud. It supports multiple messaging protocols. RabbitMQ can be deployed in distributed and federated configurations to meet high-scale, high-availability requirements.

What is Docker

Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package. By doing so, thanks to the container, the developer can rest assured that the application will run on any other Linux machine regardless of any customized settings that machine might have that could differ from the machine used for writing and testing the code.

What is pipenv

Pipenv is a tool that aims to bring the best of all packaging worlds (bundler, composer, npm, cargo, yarn, etc.) to the Python world. Windows is a first-class citizen, in our world.

It automatically creates and manages a virtualenv for your projects, as well as adds/removes packages from your Pipfile as you install/uninstall packages. It also generates the ever-important Pipfile.lock, which is used to produce deterministic builds.

The problems that Pipenv seeks to solve are multi-faceted:

You no longer need to use pip and virtualenv separately. They work together.
Managing a requirements.txt file can be problematic, so Pipenv uses the upcoming Pipfile and Pipfile.lock instead, which is superior for basic use cases.
Hashes are used everywhere, always. Security. Automatically expose security vulnerabilities.
Give you insight into your dependency graph (e.g. $ pipenv graph).
Streamline development workflow by loading .env files.

How to use this template

Prerequisites

Python 3.9+
pipenv installed
Docker Engine 1.13.0+
Docker Compose installed

Installing requirements

To create the virtual environment and install all libraries and packages open the terminal in the root folder of this project (same place where the pipfile is) and type pipenv install.

Initialize RabbitMQ container

docker-compose up -d

This will download the RabbiMQ image from Docker Hub and start a container with the following ports mapped:

Host	Container	Description
5672	5672	Queue port
8080	15672	Management port

Sending and reading messages

Run send.py to send a message to a queue called hello.
- command pipenv run python send.py
Run receiver.py to read all the messages in the hello queue.
- command pipenv run python receiver.py
