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

There are a variety of different components you need to have available to start using Helm. In this chapter, you learned how to install minikube to provide a local Kubernetes cluster that can be used throughout this book. You also learned how to install kubectl, which is the official tool for interacting with the Kubernetes API. Finally, you learned how to install the Helm client and explored the various ways that Helm can be configured, including adding repositories and plugins, modifying environment variables, enabling tab completion, and configuring authentication and authorization against a Kubernetes cluster.

Now that you have the prerequisite tooling installed, you can begin learning how to deploy your first application with Helm. In the next chapter, you will install a Helm chart from an upstream chart repository, as well as learn about life cycle management and application configuration. After finishing that chapter, you will have an understanding of how Helm acts...
