Auth Service

Overview

Auth Service is a crucial microservice in the BerryTracer project, designed for handling authentication and authorization for IoT devices and users. It utilizes gRPC for secure and efficient inter-service communication.

Features

• Secure authentication for users and devices.
• Authorization management.
• Reliable gRPC communication for inter-service interactions.
• MongoDB integration for persistent data storage.

Prerequisites

• Go (version 1.15 or later is recommended).
• An active MongoDB instance.
• Other dependent services (like device-service) should be running and accessible (configured via environment variables).

Installation

Clone the Auth Service repository:

git clone https://github.com/BerryTracer/auth-service.git
cd auth-service

Set up the environment variables in a .env file:

MONGODB_URI=mongodb://root:password@localhost:27017/berrytracer
DEVICE_SERVICE_URL=localhost:50051

Running the Service

To run the Auth Service locally:

go run main.go

Docker Compose

To start MongoDB using Docker Compose:

docker-compose -f docker-compose.dev.db.yml up -d

Ensure the MongoDB URI in the .env file matches the configuration in the Docker Compose file.

Project Structure

• /grpc: gRPC service definitions and protocol buffers.
• /model: Data models related to authentication and authorization.
• /repository: Database operations and data access layer.
• /service: Business logic and service handlers for authentication.
• main.go: The main entry point for the Auth Service.

Development

Build the project:

go build -o auth-service

Run tests:

go test ./...
