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.

Using Helm

Helm is a rich package management system that lets you perform all the necessary steps to manage the applications installed on your cluster. Let’s roll up our sleeves and get going. We’ll look at installing both Helm 2 and Helm 3, but we will use Helm 3 for all of our hands-on experiments and demonstrations.

Installing Helm

Installing Helm involves installing the client and the server. Helm is implemented in Go. The Helm 2 executable can serve as either the client or server. Helm 3, as mentioned before, is a client-only program.

Installing the Helm client

You must have Kubectl configured properly to talk to your Kubernetes cluster because the Helm client uses the Kubectl configuration to talk to the Kubernetes API server.

Helm provides binary releases for all platforms here: https://github.com/helm/helm/releases.

For Windows, the Chocolatey (https://chocolatey.org) package manager is the best option (usually up to date):

choco install...
