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.

Running a Cassandra cluster in Kubernetes

In this section, we will explore in detail a very large example of configuring a Cassandra cluster to run on a Kubernetes cluster. I will dissect and give some context for interesting parts. If you wish to explore this even further, the full example can be accessed here:

The goal here is to get a sense of what it takes to run a real-world stateful workload on Kubernetes and how StatefulSets help. Don’t worry if you don’t understand every little detail.

First, we’ll learn a little bit about Cassandra and its idiosyncrasies, and then follow a step-by-step procedure to get it running using several of the techniques and strategies we covered in the previous section.

A quick introduction to Cassandra

Cassandra is a distributed columnar data store. It was designed from the get-go for big data. Cassandra is fast, robust (no single point of...
