About The Project

The goal of this project is to containerize and define the deployment of a simple web poll application

There are five elements constituting the application, connected in a container :

Poll, a flask Python web application that gathers votes and push them into a Redis queue.
Redis, which holds the votes sent by the Poll application, awaiting for them to be consumed by the Worker.
Worker, a java application which consumes the votes being in the Redis queue, and stores them into a PostgreSQL database
PostgreSQL database, which (persistently) stores the votes stored by the Worker.
Result, a Node.js web application that fetches the votes from the database and displays the. . . well, result.

Check that Docker is installed on your computer and let's start ! Clone the repositorie and build images with Docker-compose

docker-compose up --build

you can see the Poll on localhost:5000/ and the Result on localhost:5001/

Do not forget to down containers

docker-compose down -v
