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.

Chapter 5: Building Your First Helm Chart

In the previous chapter, you learned about the various aspects that comprise a Helm chart. Now, it is time to put this knowledge to the test by building a Helm chart. Learning to build a Helm chart will allow you to package a complex Kubernetes application in a way that makes it simple to deploy.

In this chapter, you will learn how to build a Helm chart that deploys the guestbook application, a common quickstart application used throughout the Kubernetes community. This chart will be built by following best practices around Kubernetes and Helm chart development, to provide a well-written and easily maintainable piece of automation. Throughout the process of developing this chart, you will learn many different skills that you can apply toward building your own Helm charts. At the end of the chapter, you will learn how to package your Helm chart and deploy it to a chart repository, where it can be easily accessible to end users.
