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 9: Helm Security Considerations

As you have likely come to realize throughout this book, Helm is a powerful tool that presents many deployment possibilities to users. This power can, however, get out of hand if certain security paradigms are not recognized and followed. Luckily, Helm provides many ways to incorporate security into everyday usage in ways that are simple to achieve, from the moment the Helm CLI is downloaded to the moment a Helm chart is installed on a Kubernetes cluster.

In this chapter, we will cover the following topics:

  • Data provenance and integrity
  • Helm chart security
  • Additional considerations around RBAC, values, and chart repositories
