The Kubernetes API is comprehensive and encompasses the entire functionality of Kubernetes. As you may expect, it is huge. But it is designed very well using best practices, and it is consistent. If you understand the basic principles, you can discover everything you need to know. We covered the Kubernetes API itself in Chapter 1, Understanding Kubernetes Architecture. If you need a refresher, go and take a look. In this section, we’re going to dive deeper and learn how to access and work with the Kubernetes API.
