Containerized Microservices in Golang

Multi-Cluster & Canary Deployment with Kubernetes and Helm

---

📌 Overview

This repository contains a containerized Golang HTTP microservice that demonstrates modern cloud-native deployment practices, including:

• Golang-based backend service
• Docker containerization
• Kubernetes deployment using Helm
• Multi-cluster Kubernetes setup
• Canary deployment strategy

The project is designed for learning and showcasing DevOps and Kubernetes concepts using a simple but realistic microservice.

🚀 Application Features

The Go service exposes the following HTTP endpoints:

• GET /
  Returns a simple message indicating the application is running.

• GET /health
  Returns JSON health status with a timestamp.

• GET /details
  Returns the hostname and IP address of the running container or Kubernetes pod.
