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.

Provisioning managed clusters and node pools

There are different methods for provisioning clusters and node pools. You should choose the method that is best for your use case wisely because failure here can result in devastating outages. Let’s review some options. All cloud providers offer cluster and node pool provisioning via APIs, CLIs, and UIs. I highly recommend avoiding directly using any of these methods and instead using GitOps-based declarative approaches. Here are some solid options to consider.

The Cluster API

The Cluster API is an open-source project from the Cluster Lifecycle SIG. Its goal is to make provisioning, upgrading...
