To get the most out of this book

This book will cover downloading and running the Kubernetes project. You'll need access to a Linux system (VirtualBox will work if you are on Windows) and some familiarity with the command shell. To follow the examples in each chapter, you need a recent version of Docker and Kubernetes installed on your machine, ideally Kubernetes 1.10. If your operating system is Windows 10 Professional, you can enable hypervisor mode; otherwise, you will need to install VirtualBox and use a Linux guest OS.

Additionally, you should have a Google Cloud Platform account. You can sign up for a free trial here: https://cloud.google.com/.

Also, an AWS account is necessary for a few sections of the book. You can sign up for a free trial here: https://aws.amazon.com/.
