Day 25: Building Microservices

Overview

This day focuses on Building Microservices in Go. You will learn how to design and implement microservices using Go and explore frameworks like go-kit and micro.

Tasks

• Task 1: Build a simple microservice with RESTful endpoints.
• Task 2: Use go-kit to implement a microservice with service discovery and logging.
• Task 3: Deploy multiple microservices and enable communication between them.

Resources

• Go-Kit Documentation
• Micro Framework Documentation
• Designing Microservices

Example Code

// Example: Simple Microservice with RESTful Endpoints
package main

import (
    "encoding/json"
    "fmt"
    "net/http"
)

type Response struct {
    Message string `json:"message"`
}

func helloHandler(w http.ResponseWriter, r *http.Request) {
    response := Response{Message: "Hello, Microservices!"}
    w.Header().Set("Content-Type", "application/json")
    json.NewEncoder(w).Encode(response)
}

func main() {
    http.HandleFunc("/hello", helloHandler)
    fmt.Println("Microservice running on port 8080")
    http.ListenAndServe(":8080", nil)
}

Exercises

• Build a RESTful microservice with endpoints for CRUD operations.
• Use go-kit to add service discovery and logging to your microservice.
• Deploy multiple microservices and enable communication using gRPC or HTTP.
