preface
Thank you for your interest in Acing the Certified Kubernetes Administrator Exam, Second Edition. Rafael Brito joins as my co-author, bringing his many years of valuable industry knowledge and experience to you, the reader. We have thoroughly revised the book with updated study materials for the new CKA exam to reflect the changes to the domains and objectives.
To some, Kubernetes is considered overly complex and challenging to learn, as it abstracts away many components of a Linux system. I’m not going to pretend that’s not true, but I think we’ve done a great job in this book of explaining each component—to pull back the curtain, so to speak, and provide greater context, helping you better grasp concepts through real-world examples. Although this book is focused on the exam, I think it’s also a good resource to learn the fundamentals of Kubernetes. However, if you’d like to dive deeper into a specific topic, fortunately, there are many other valuable resources available. For example, the book Kubernetes in Action, by Marko Lukša, is the book I recommend most often.
