Project Overview

Our project is a microservice-based web application that consists of five different services: Redis, Postgres DB, Vote App, Worker App, and Result App. The purpose of the application is to allow users to vote for their preferred option and display the results of the poll in real time.

To automate the deployment process of this application, we have set up a CI/CD pipeline using Jenkins. The pipeline consists of several stages, including code checkout, building Docker images, deploying services to different servers using Docker Compose, updating the Docker registry, sending notification emails to the concerned person, and performing cleanup tasks on the hosting server.

By setting up this pipeline, we aim to streamline the deployment process of our microservice application and ensure that each new change to the codebase is automatically deployed to the production/ testing/ development environment. This approach will save us time and effort while ensuring the reliability and scalability of our application.
