Getting Started with Kustomize
Managing subtly different variations of Kubernetes configuration is really hard. This course will teach you how to use Kustomize to transform static base configurations into multiple variations to suit different environments.
What you'll learn
It's tough to reliably manage the small Kubernetes configuration changes required to allow apps to run in multiple environments. In this course, Getting Started with Kustomize, you’ll learn how to use Kustomize to manage variations of an original set of base configurations. First, you'll discover how to define Kustomizations as the building block for performing configuration transformations. Next, you'll explore how to alter the metadata associated with Kubernetes objects on a per environment basis. And finally, you'll learn how to patch objects to add or remove configuration items to suit the environment at hand. When you’re finished with this course, you’ll have the skills and knowledge that will enable you to work with template-free Kubernetes configuration, using Kustomize.
