To get the most out of this book
Since Kubernetes is based on containers, some examples in this book may use containers that have changed since publishing. Other illustrative examples may use containers that do not publicly exist in Docker Hub. These examples should be used as a basis for running your own application containers.
In some cases, open source software like Kubernetes can have breaking changes. The book is up to date with Kubernetes 1.19, but always check the documentation (for Kubernetes and for any of the other open source projects covered in the book) for the most up-to-date information and specifications.
If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
