In this project, I implemented a fully automated CI/CD pipeline for a Spring Boot application using Jenkins, Docker, MySQL, SonarQube, and Nexus. The pipeline handles every stage of the development lifecycle, from code retrieval to deployment.

Key Stages: Clone Repo: Fetch latest code from GitHub.

Create Docker Network: Enable container communication.

MySQL Container: Launch MySQL with app-specific DB.

Build App Image: Create a Docker image for the Spring Boot app.

Run App Container: Start the app, connect to MySQL.

Health Check: Verify app status via /actuator/health.

Test Execution: Run unit and integration tests with Maven.

SonarQube Analysis: Perform static code quality checks.

Nexus Deployment: Push JAR artifact to Nexus.

Push Docker Image: Upload the Docker image to a Nexus Docker repo.

Cleanup: Remove unused Docker images.

This automated pipeline ensures smooth continuous integration and delivery, making the development process efficient and reliable.
