About the Book

Stop paying for idle clusters. Master Kubernetes v1.35+ locally.

Are you tired of "Hello World" tutorials that don't survive in Production? Do you want to learn Kubernetes without expecting a surprise bill from AWS or Google Cloud at the end of the month?

Kubernetes has become the operating system of the cloud, but its learning curve is steep. Most courses make two mistakes: they are either pure abstract theory, or they force you to spend money on managed clusters (EKS, GKE) just to learn the basics.

"Once Upon a Time Kubernetes" breaks that barrier.

This is not just a reading book; it is a battle manual designed for Engineers, Developers, and SysAdmins who want to move from "playing" with Kubernetes to truly understanding it.

🛠️ The "Local-First" Approach

Forget about obsolete Minikube or heavy virtual machines. In this book, you will master Kind (Kubernetes in Docker) to deploy full multi-node clusters directly on your laptop.

Your learning environment will include:

  • Multi-node Cluster: Simulate a real production environment with control-plane and workers.
  • Real Networking: You will implement MetalLB to simulate real Load Balancers on your PC.
  • Ingress & Gateway API: Master modern traffic entry points.
  • Persistence: Manage volumes (PV/PVC) that survive restarts.

📚 Learning Path (From Zero to Hero)

The content is structured to take you from fundamentals to advanced concepts using the latest Kubernetes v1.35+:

  1. Cloud Native Architecture: Finally understand Pods, ReplicaSets, and Deployments.
  2. Configuration Management: ConfigMaps, Secrets, and security best practices.
  3. Security: RBAC (Role-Based Access Control) and ServiceAccounts.
  4. Resources: CPU/RAM limits and Autoscaling (HPA).
  5. Real World: How to translate what you learned locally to the cloud (AWS, Google Cloud, DigitalOcean).

🌟 Why this book?

  • Updated for 2026: Covers Kubernetes v1.35.
  • Cost-Efficient: You don't need a cloud account. Your laptop is your data center.
  • Hands-on: Includes access to a GitHub repository with all the YAML manifests and scripts.
  • Kubexercises: Includes a self-assessment tool to test your knowledge after each chapter.

Start deploying your first cluster in 40 seconds. Grab your copy now and level up your DevOps career.
