Microservices Architecture

This project demonstrates a microservices architecture using Go, gRPC, Redis, and Docker. It consists of three main services:

1. Auth Service (gRPC)
2. Order Service (Redis)
3. Product Service (HTTP)

Services Overview

Auth Service (auth-grpc-microservice)

• Handles user authentication and authorization
• Implements gRPC for communication
• Port: 8000

Order Service (order-redis-microservice)

• Manages order processing and storage
• Uses Redis for data persistence
• Port: 8081

Product Service (product-service)

• Provides product information and handles product-related operations
• Acts as an API gateway, communicating with both Auth and Order services
• Port: 8082

Prerequisites

• Docker
• Docker Compose
• Go 1.21 or later (for local development)

Getting Started

1. Clone the repository:

   git clone https://github.com/caiotheodoro/microservices-project.git
   cd microservices-project
   

2. Build and run the services using Docker Compose:

   docker-compose up --build
   

3. The services will be available at:

   • Auth Service: localhost:8000 (gRPC)
   • Order Service: http://localhost:8081
   • Product Service: http://localhost:8082

API Endpoints

Product Service

• GET /products: Retrieve a list of products
• POST /order: Create a new order
• GET /health: Check the health of the service

Development

To run the services locally for development:

1. Install dependencies for each service:

   cd auth-grpc-microservice && go mod download
   cd ../order-redis-microservice && go mod download
   cd ../product-service && go mod download
   

2. Run each service individually:

   cd auth-grpc-microservice && go run cmd/main.go
   cd ../order-redis-microservice && go run main.go
   cd ../product-service && go run cmd/main.go
