Overview of this book

The fourth edition of the bestseller Mastering Kubernetes includes the most recent tools and code to enable you to learn the latest features of Kubernetes 1.25. This book contains a thorough exploration of complex concepts and best practices to help you master the skills of designing and deploying large-scale distributed systems on Kubernetes clusters. You’ll learn how to run complex stateless and stateful microservices on Kubernetes, including advanced features such as horizontal pod autoscaling, rolling updates, resource quotas, and persistent storage backends. In addition, you’ll understand how to utilize serverless computing and service meshes. Further, two new chapters have been added. “Governing Kubernetes” covers the problem of policy management, how admission control addresses it, and how policy engines provide a powerful governance solution. “Running Kubernetes in Production” shows you what it takes to run Kubernetes at scale across multiple cloud providers, multiple geographical regions, and multiple clusters, and it also explains how to handle topics such as upgrades, capacity planning, dealing with cloud provider limits/quotas, and cost management. By the end of this Kubernetes book, you’ll have a strong understanding of, and hands-on experience with, a wide range of Kubernetes capabilities.

Packaging Applications

In this chapter, we are going to look into Helm, the popular Kubernetes package manager. Every successful and non-trivial platform must have a good packaging system. Helm was developed by Deis (acquired by Microsoft in April 2017) and later contributed to the Kubernetes project directly. It became a CNCF project in 2018. We will start by understanding the motivation for Helm, its architecture, and its components. Then, we’ll get hands-on and see how to use Helm and its charts within Kubernetes. That includes finding, installing, customizing, deleting, and managing charts. Last but not least, we’ll cover how to create your own charts and handle versioning, dependencies, and templating.

The topics we will cover are as follows:

  • Understanding Helm
  • Using Helm
  • Creating your own charts
  • Helm alternatives
