Overview of this book

Containerization is currently known to be one of the best ways to implement DevOps. While Docker introduced containers and changed the DevOps era, Google developed an extensive container orchestration system, Kubernetes, which is now considered the frontrunner in container orchestration. With the help of this book, you’ll explore the efficiency of managing applications running on Kubernetes using Helm. Starting with a short introduction to Helm and how it can benefit the entire container environment, you’ll then delve into the architectural aspects, in addition to learning about Helm charts and its use cases. You’ll understand how to write Helm charts in order to automate application deployment on Kubernetes. Focused on providing enterprise-ready patterns relating to Helm and automation, the book covers best practices for application development, delivery, and lifecycle management with Helm. By the end of this Kubernetes book, you will have learned how to leverage Helm to develop an enterprise pattern for application delivery.

Cleaning up your Kubernetes environment

First, run the following command to remove your Guestbook CRD:

$ kubectl delete crd

Before you proceed with the next clean-up steps, note that one of the questions posed later under the Questions section will challenge you with writing your own Helm charts to implement the chart designs discussed under the Using Helm to manage Operators and CRs section. You may want to postpone these steps to test your implementation.

To continue the clean-up, run the following command to delete your chapter8 namespace:

$ kubectl delete ns chapter8

Finally, run the minikube stop command to stop your Minikube VM.
