Review
“If you’re preparing for an interview where Kubernetes is on the agenda—or you want a dependable resource between meetings—this book will help you systematize your knowledge, avoid traps, and communicate like someone who runs these systems in production. It won’t give you shortcuts; it gives you something better: a clear mental model, practical examples, and repeatable ways to reason under pressure. I recommend it.”
