E-commerce Microservices Platform

A DevOps project to build a scalable e-commerce application using microservices, targeting AWS deployment.

Overview

This project implements four microservices to simulate an e-commerce platform:

• User Service: Manages user data (Java, Spring Boot).
• Product Service: Handles product catalog (Node.js, Express).
• Order Service: Processes orders by calling User and Product (Python, Flask).
• Recommend Service: Suggests products by calling Product (Go).

Architecture

• Microservices: REST APIs running locally on ports 8080 (User), 3000 (Product), 5000 (Order), 8081 (Recommend).
• Communication: Services interact via HTTP GET requests.
• Error Handling: Graceful failures for unavailable services.
• Future: Docker, Kubernetes, CI/CD, monitoring on AWS Free Tier.

Setup and Running Locally

1. Clone the Repo:

   git clone https://github.com/charan-happy/Ecommerce-Microservices-DevOps-project.git
   cd Ecommerce-Microservices-DevOps-project

2. Install Dependencies:

• User: cd user-service && mvn package
• Product: cd product-service && npm install
• Order: cd order-service && pip3 install -r requirements.txt
• Recommend: cd recommend-service && go mod tidy

3. Run Services (in separate terminal):

• User: java -jar target/user-service-1.0-SNAPSHOT.jar
• Product: node app.js
• Order: python3 app.py
• Recommend: go run main.go

4. Test Endpoints:

• curl http://localhost:8080/users

• curl http://localhost:3000/products

• curl http://localhost:5000/orders

• curl http://localhost:8081/recommend

• curl -X POST -H "Content-Type: application/json" -d '{"user_id": 1, "product_id": 101}'

User Interface

• User Management: Visit http://localhost:8080/ to add, update, or delete users.
• Product Management: Visit http://localhost:3000/ to add or delete products.

CI Pipeline

• GitHub Actions: Automated CI pipeline (.github/workflows/ci.yml):
  • Builds Docker images for all services.
  • Runs API health checks and unit tests.
  • Triggered on push/pull to main

API Endpoints

• User Service:
  • GET /users: List all users.
  • GET /users/{id}: Get user by ID.
  • POST /users: Create user ({"name": "Alice"}).
  • PUT /users/{id}: Update user.
  • DELETE /users/{id}: Delete user.
• Product Service:
  • GET /products: List all products.
  • GET /products/{id}: Get product by ID.
  • POST /products: Create product ({"name": "Phone", "price": 499}).
  • PUT /products/{id}: Update product.
  • DELETE /products/{id}: Delete product.
• Order Service:
  • POST /orders: Create order ({"user_id": 1, "product_id": 101}).
• Recommend Service:
  • GET /recommend: Get recommended product.
