Kubernetes Tutorial Chapter 2: GitOps with ArgoCD

Introduction

In the previous chapter, we set up a local Kubernetes cluster using Docker Desktop and deployed a simple React application using traditional imperative commands. While this approach works for learning and small-scale deployments, it doesn’t scale well for production environments where multiple team members need to collaborate on deployments, track changes, and maintain consistency across environments.

This is where GitOps comes in - a modern approach to managing Kubernetes deployments that leverages Git as the single source of truth for declarative infrastructure and applications.
