3-Tier Application CI/CD Pipeline with Docker and GitHub Actions

Overview

This project demonstrates a 3-tier application CI/CD pipeline implemented using Docker and GitHub Actions. The pipeline automates code changes, triggering builds, tests, and deployments into Docker containers. These containers are then deployed to an EC2 instance, ensuring a seamless and efficient delivery process for modern applications.

---

Key Features

• Code Integration: Automatically triggers builds and tests upon code changes in the GitHub repository.
• Containerization: Applications are containerized using Docker for consistent and scalable deployments.
• Continuous Deployment: The final Docker image is pushed to an EC2 instance for production.
• End-to-End Automation: Fully automated pipeline from code commit to deployment.

---

Architecture

1. Development: Developers push code changes to the GitHub repository.
2. CI/CD Trigger: GitHub Actions triggers the pipeline.
   • Build Stage: Builds a Docker image from the latest code.
   • Test Stage: Runs unit and integration tests on the container.
   • Deploy Stage: Pushes the Docker container to an EC2 instance.
3. Deployment: Dockerized application runs on the EC2 instance, ready to serve users.

Prerequisites

1. Docker Installed: Ensure Docker is installed on your local system.
2. AWS EC2 Instance: Launch an EC2 instance with the necessary configurations.
3. GitHub Repository: Fork or clone the repository to work locally.
4. GitHub Actions Setup: Configure secrets for AWS access keys and EC2 details in your repository settings.

CI/CD Pipeline Details

1. Build:

   • Creates a Docker image using the Dockerfile.
   • Ensures the image meets quality and security standards.

2. Test:

   • Runs all unit and integration tests within the container.
   • Outputs test results to the pipeline logs.

3. Deploy:

   • Connects to the EC2 instance using SSH.
   • Pulls the Docker image and runs the container in production.
