🚀 Python Microservice CI/CD on AWS ECS with GitHub Actions

This project demonstrates how to build, containerize, and deploy a Python microservice onto AWS ECS (Fargate) using a complete CI/CD pipeline powered by GitHub Actions.

It’s designed to showcase DevOps best practices like Infrastructure as Code, automated builds, containerization, and continuous deployment.

---

📌 Project Overview

• Microservice: A simple Python Flask application with two endpoints:

  • / → returns Hello from Python microservice on ECS!
  • /health → returns JSON {"status": "ok"}

• Containerization: Packaged with Docker and pushed to Amazon Elastic Container Registry (ECR).

• Deployment: Hosted on Amazon ECS (Fargate) inside a VPC and exposed through a public Application Load Balancer (ALB).

• CI/CD: Fully automated pipeline with GitHub Actions:

  • On each push → Code is built, containerized, pushed to ECR, and deployed to ECS.

---

⚙️ Tech Stack

• Programming: Python (Flask)
• Containerization: Docker
• Cloud Provider: AWS
  • ECS (Fargate)
  • ECR
  • IAM
  • VPC & Subnets
  • Security Groups
  • ALB
• CI/CD: GitHub Actions

---

Flow:

1. Developer pushes code to GitHub.
2. GitHub Actions workflow triggers.
3. Docker image is built and pushed to ECR.
4. ECS (Fargate) automatically pulls the image and redeploys the service.
5. The service is accessible via ** Public IP**.

---

🔑 Key Features

• End-to-End Automation: No manual steps needed once pipeline is set.
• Scalable & Serverless: Uses AWS ECS with Fargate, no EC2 management.
• Health Check Endpoint: /health for monitoring readiness & uptime.
• Professional CI/CD Flow: Recruiters can see practical DevOps implementation.

🌍 Live Test Output

After deployment, the service responds:

$ curl http://13.223.80.162:5000/
Hello from Python microservice on ECS!

$ curl http://13.223.80.162:5000/health
{"status":"ok"}
