Any software requirements are either listed at the beginning of each chapter in the Technical requirements section, or, if the installation of a particular piece of software is part of the material of the chapter, then any instructions you need will be contained within the chapter itself. Most of the installations are software components that are installed into the Kubernetes cluster. This is an important part of the hands-on nature of the book.
