Go Microservices Project

A comprehensive microservices application built with Go, Docker, and Kubernetes.

Technologies Used

• Go: Backend services
• Docker: Containerization
• Kubernetes: Container orchestration
• RabbitMQ: Message broker
• PostgreSQL: SQL database
• MongoDB: NoSQL database
• gRPC: Internal service communication
• RESTful API: External communication

Architecture

This project consists of the following microservices:

1. Broker Service: API Gateway that routes requests to appropriate services
2. Authentication Service: Handles user authentication
3. Logger Service: Centralized logging with MongoDB
4. Mail Service: Handles email sending
5. Listener Service: Consumes messages from RabbitMQ

Getting Started

Prerequisites

• Go 1.21+
• Docker and Docker Compose
• Kubernetes (minikube or Docker Desktop)
• Make

Running with Docker Compose

make ./project/up_build

Running with Kubernetes

# Apply Kubernetes manifests
kubectl apply -f ./project/k8s

# Start minikube
minikube start

# Expose Broker Service
kubectl expose deployment broker-service --type=LoadBalancer --port=8080 --target-port=8080

# To make accessible LoadBalancer
minikube tunnel

# To see minikube dashboard
 minikube dashboard
#
