December 2025 Release : Third Edition

The third major release of Conquer CKA Exam is now live.

The first edition was released over a year ago. Since then, the book has gone through three iterations, shaped by feedback from nearly 100 readers on Payhip and Gumroad.

This December release is the most refined version so far. It took three months of focused work and significantly improves on the original with clearer labs, better exam-style scenarios, and a tighter focus on what actually matters in the CKA.

Some people learn best by watching videos.

Others need to slow down, read, think, and practice.

I’m in the second group.

I don’t learn Kubernetes passively. I learn by reading documentation, running commands, breaking things, and fixing them again. That’s how the knowledge sticks.

This book exists because I couldn’t find a CKA resource built that way, so I made one, and kept improving it.

If that’s how you learn too, this book is for you. 🤗

If This Helped You, Share It

If you find this book useful, feel free to share it with someone preparing for the CKA.

I’m confident in what’s inside because it’s been built slowly, tested by real readers, and improved based on real feedback. If it helps you think more clearly under exam pressure, it will likely help someone else too.

This Book Is About Practice

If your goal is to pass the CKA, theory alone will not get you there.

You need to practice under pressure. You need to see real failures. You need to make decisions quickly and understand why they work.

Every scenario in this book is written to feel like the exam. The tasks are direct. The constraints are real. The mistakes are the same ones people actually make during the test.

There is no noise here. No videos playing in the background. No distractions.

Just you, the task, and the cluster.

What You Will Get

• More than 50 real exam style scenarios
• Step by step lab walkthroughs with full command output
• Time saving techniques that matter when the clock is running
• Common mistake patterns and how to fix them fast
• Clear ways to think through each problem instead of guessing

This is not passive reading. It is hands on repetition that builds confidence.

Aligned with the February 2025 CKA Exam

This book is not selective. It does not focus on only popular topics or safe scenarios.

It covers everything the CKA exam expects you to handle, including the small details that usually catch people off guard.

You will work through:

• Core Kubernetes fundamentals reinforced through real scenarios, not definitions
• Full cluster lifecycle tasks including upgrades, node maintenance, draining, rescheduling, and verification
• Storage end to end, including PVs, PVCs, StorageClasses, expansion, binding behavior, StatefulSets, and stateful applications
• Networking from multiple angles, including Ingress, Gateway API, TLS termination, service exposure, and traffic routing
• NetworkPolicies in depth, covering namespace isolation, cross namespace traffic, ingress and egress rules, and denial scenarios
• Scheduling behavior in real conditions, including node selectors, affinities, taints and tolerations, PriorityClasses, and PodDisruptionBudgets
• Resource management with requests, limits, quotas, and real resource pressure scenarios
• Autoscaling with Horizontal Pod Autoscaler and its interaction with metrics and limits
• Configuration management using ConfigMaps and Secrets in practical workloads
• Helm from installation to customization, upgrades, rollbacks, and clean uninstalls
• CustomResourceDefinitions, including creating, inspecting, and using CRDs in real workflows
• Control plane and node level troubleshooting, including CrashLoopBackOff, NotReady nodes, disk pressure, DNS failures, CNI issues, and kubelet problems
• Security focused tasks including RBAC, ClusterRoles, ServiceAccounts, permission testing, and certificate management
• Exam level debugging scenarios that force you to read errors, inspect state, and fix what is actually broken

Nothing here is theoretical. Every topic appears as a task you must complete, verify, and understand under realistic conditions.

This is full domain coverage for the February 2025 CKA, built from the perspective of how the exam actually behaves, not how Kubernetes is usually taught.

How the Book Works

Each scenario follows the same simple flow:

1. Read the task
2. Solve it in your own cluster
3. Compare your work with the full solution and screenshots
4. Understand the reasoning behind each decision

By the time you reach the exam, the workflow feels familiar.

Who This Book Is For

• CKA candidates who want a clear and structured path
• Engineers who want real Kubernetes confidence, not memorized notes
• Instructors who want practical labs they can reuse

If you learn best in quiet focus, this book was written for you.

Additional details

A Free Edition is available with a smaller set of scenarios so you can evaluate the format and depth before buying the full version.

Reader Feedback (from email)

★★★★★

"Below is from my final drill list, these are the specific items I felt your guide did the best job covering. The topic areas are based on what I felt I needed the most reinforcement (like taints and tolerations which I haven't used a lot of in practice) or things I had little/no experience with (HPA, Gateway API). 

Here's representative feedback on one scenario:

4-21-scenario-21-exposing-a-service-using-gateway-api  

The Objective and Context given for the scenario are great and set the stage for the involved technology(ies) and procedures.

The References section provides background, further reading.

The Always Remember section provides valuable reminders focused on mastering the technology exam.

The Exam Tip section provides helpful, practical guidance for exam success." - Jerry N.

★★★★★

"I found the following sections particularly helpful:

• The step-by-step instructions: These guides taught me how to be organized for the exam and how to approach the reasoning behind the scenarios more strategically.
• The Exam Tips: These are extremely important for making me aware of common mistakes so I can practice avoiding them." - Majid Z.
