Day 26: Service Mesh Integration

Overview

This day focuses on Service Mesh Integration in Go. You will learn how to integrate Go applications with service meshes like Istio and Linkerd to manage traffic, observability, and security.

Tasks

• Task 1: Set up a service mesh (e.g., Istio or Linkerd) in a Kubernetes cluster.
• Task 2: Deploy a Go microservice and integrate it with the service mesh.
• Task 3: Use the service mesh to implement traffic splitting and observability.

Resources

• Istio Documentation
• Linkerd Documentation
• Service Mesh Patterns

Example Code

// Example: HTTP Server for Service Mesh Integration
package main

import (
    "fmt"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello from Service Mesh Integrated App!")
}

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

Exercises

• Deploy a Go microservice to a Kubernetes cluster with Istio or Linkerd installed.
• Use the service mesh to implement traffic splitting between two versions of the microservice.
• Enable observability features like tracing and metrics for the Go microservice using the service mesh.
