CI/CD Pipeline for Spring Boot CRUD App on AWS ECS

CI/CD Pipeline for Spring Boot

Overview

This project demonstrates a real-world CI/CD pipeline for deploying a Java Spring Boot CRUD application using GitLab CI/CD and AWS ECS (Fargate).
The application is containerized with Docker, stores data in AWS RDS MySQL, and follows production-ready DevOps practices.

It showcases how to automate build, test, and deployment workflows with scalability, security, and zero-downtime deployments in mind.

Architecture

GitLab CI/CD for pipeline automation
Docker for containerization
AWS ECR for container image storage
AWS ECS (Fargate) for container orchestration
AWS RDS MySQL for database persistence
AWS EFS for shared storage (if required)

Key Highlights

✅ Spring Boot CRUD web application
✅ Dockerized and deployed on AWS ECS (Fargate)
✅ Automated GitLab CI/CD pipeline
✅ AWS RDS MySQL integration
✅ Zero-downtime deployment strategy
✅ Secure, scalable, production-ready workflow

Why This Project Matters

This project reflects end-to-end DevOps ownership, combining:
Backend engineering (Spring Boot & MySQL)
CI/CD automation (GitLab pipelines)
Containerization (Docker)
Cloud-native deployment (AWS ECS)
It demonstrates my ability to design, automate, and deploy production-grade applications.

Use Cases
