How to Use This Tutorial
- Work through the chapters in order — each one builds on the previous.
- Type every command — do not copy-paste blindly. Muscle memory matters.
- Complete the exercises — every chapter ends with 5 hands-on exercises.
- Break things on purpose — misconfigure a sync policy, introduce a bad manifest, then fix it.
- Build the practice projects — Chapter 15 ties everything together.
Environment: All examples work with Argo CD 2.9+ on any Kubernetes cluster — Minikube, kind, EKS, GKE, or AKS.
