⬅ Back to Intro | Next → Part 3 – Understanding Sidecar Injection and Traffic Flow 💡 This post is part of my Istio Hands-on Series — a practical journey into Kubernetes Service Mesh. Each post builds on the previous one with hands-on labs, real command outputs, and clear explanations aimed at learning Istio by doing, not just reading. Objective In this post, we’ll set up our local playground for the Istio Hands-on series.You’ll learn how to: ...

The best way to learn is by doing — and sharing what you learn. 👋 Introduction Over the past few years, Kubernetes has become the de-facto standard for running microservices. It simplifies deployment, scaling, and management — but as applications grow, so does the complexity of how those services talk to each other.
