To get the most out of this book
It is assumed that you have at least a foundational understanding of basic Kubernetes concepts and terms due to the fact that the Operator Framework builds heavily on these concepts to serve its purpose. These include topics such as basic application deployment and a familiarity with command-line tools such as kubectl for interacting with Kubernetes clusters. While direct hands-on experience with these topics is not necessary, it will be helpful.
In addition, administrator access to a Kubernetes cluster is needed in order to complete all of the sample tasks in the book (for example, deploying an Operator in Chapter 6, Building and Deploying Your Operator). The chapters that require a Kubernetes cluster offer some options for creating disposable clusters and basic setup steps for doing so, but in order to focus on the main content, these sections intentionally do not go into thorough detail regarding cluster setup. It is strongly recommended to use a disposable cluster for all examples in order to avoid accidental damage to sensitive workloads.
If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book's GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
