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.

Invoking the Helm CLI in CI and CD pipelines is an efficient way of further abstracting the capabilities that Helm provides. Chart developers can automate the end-to-end chart development process by writing a CI pipeline that lints, tests, packages, and releases charts to a chart repository. End users can write a CD pipeline that uses Helm to deploy a chart across multiple different environments, leveraging GitOps to ensure applications can be deployed and configured as code. Writing pipelines helps developers and companies scale applications faster and more easily by abstracting and automating processes that could otherwise become tedious and introduce human error.

In the next chapter, we will introduce another option for abstracting the Helm CLI—writing a Helm operator.
