Overview of this book

Containerization is one of the best ways to implement DevOps, and learning how to execute it effectively is an essential part of a developer’s skillset. Kubernetes is the current industry standard for container orchestration. This book will help you discover the efficiency of managing applications running on Kubernetes with Helm. Starting with a brief introduction to Helm and its impact on users working with containers and Kubernetes, you’ll delve into the primitives of Helm charts and their architecture and use cases. From there, you’ll understand how to write Helm charts in order to automate application deployment on Kubernetes and work your way toward more advanced strategies. These enterprise-ready patterns are focused on concepts beyond the basics so that you can use Helm optimally, looking at topics related to automation, application development, delivery, lifecycle management, and security. By the end of this book, you’ll have learned how to leverage Helm to build, deploy, and manage applications on Kubernetes.

Summary

In this chapter, you learned about different topics around security that pertain to Helm usage. First, you learned how to prove the data provenance and integrity of Helm releases and Helm charts. Next, you learned about Helm chart security and how a chart developer can leverage security best practices to write a stable and secure Helm chart. Then, we focused on using RBAC to create an environment based on the Principle of Least Privilege, and we finished by talking about how chart repositories can be secured using authentication and TLS. Now, by employing each of these concepts, you are well equipped to create a secure Helm architecture and working environment.

Thank you for reading Managing Kubernetes Resources Using Helm! We hope that this book helps you be confident and efficient as you use Helm to work within the Kubernetes ecosystem.
