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

After doing some hard work on developing a Helm chart, nothing beats the feeling of finally publishing your Helm chart to a repository for the world to see! In this chapter, we learned about HTTP and OCI Helm chart repositories. HTTP repositories allow you to publish your charts to simple web servers, while OCI registries allow you to publish your Helm charts alongside your container images. To practice, we published the Guestbook Helm chart to GitHub Pages (an HTTP server) and GitHub’s container registry (an OCI registry).

In the next chapter, we will learn about the tooling and strategies behind testing Helm charts.
