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.

Exploring Kubernetes Networking

In this chapter, we will examine the important topic of networking. Kubernetes as an orchestration platform manages containers/pods running on different machines (physical or virtual) and requires an explicit networking model. We will look at the following topics:

  • Understanding the Kubernetes networking model
  • Kubernetes network plugins
  • Kubernetes and eBPF
  • Kubernetes networking solutions
  • Using network policies effectively
  • Load balancing options

By the end of this chapter, you will understand the Kubernetes approach to networking and be familiar with the solution space for aspects such as standard interfaces, networking implementations, and load balancing. You will even be able to write your very own Container Networking Interface (CNI) plugin if you wish.
