by Zachary Bennett

Kubernetes custom resources provide a powerful means of extending the built-in functionality of Kubernetes. In this course, you will learn how you can use custom resources to tailor Kubernetes to the needs of your application and organization.

What you'll learn

Kubernetes comes with out-of-the-box support for most organizational needs via its built-in resources like pods and deployments. But what about those organizations that want to tailor Kubernetes to the specific needs of an application or need a little more customization? For this sort of problem, Kubernetes custom resources are the solution. In this course, Creating Custom Resources in Kubernetes, you’ll learn how to create and use custom resources in order to extend built-in Kubernetes functionality. First, you’ll explore custom resources and custom resource definitions. Next, you’ll discover custom controllers and how you can write your own custom controllers in order to set the state of a running Kubernetes cluster. Finally, you’ll learn how to write your own custom operators and schedulers in order to tailor Kubernetes to the specific needs of your application. When you’re finished with this course, you’ll have the skills and knowledge of custom resources needed to extend and customize Kubernetes.
