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.

Preparing a Kubernetes and Helm Environment

Helm is a tool that provides a variety of benefits that help users deploy and manage Kubernetes applications easier. Before users can start experiencing these benefits, however, they must satisfy several prerequisites. First, a user must have access to a Kubernetes cluster. Next, a user should have the command-line tools for both Kubernetes and Helm. Finally, a user should be aware of Helm’s basic configuration options to be productive with as little friction as possible.

In this chapter, we will outline the tools and concepts that are required to begin working with Helm. The following topics will be covered in this chapter:

  • Preparing a local Kubernetes environment with minikube
  • Setting up kubectl
  • Setting up Helm
  • Configuring Helm
