To save some money, both GCP ( https://cloud.google.com/free/) and AWS ( https://aws.amazon.com/free/) offer free tiers and trial offers for their cloud infrastructure. It's worth using these free trials for learning Kubernetes, if possible.

Most of the concepts and examples in this book should work on any installation of a Kubernetes cluster. To get more information on other platform setups, refer to the Kubernetes getting started page, which will help you pick the right solution for your cluster:  http://kubernetes.io/docs/getting-started-guides/.
