In a single sentence: Kubernetes intends to radically simplify the task of building, deploying, and maintaining distributed systems. It has been inspired by decades of real-world experience building reliable systems, and it has been designed from the ground up to make that experience if not euphoric, at least pleasant. We hope you enjoy the book!

Though no previous experience with Kubernetes is assumed, to make maximal use of the book, you should be comfortable building and deploying server-based applications. Familiarity with concepts like load balancers and network storage will be useful, though not required. Likewise, ...
