Overview of this book

Thanks to its extensive support for managing hundreds of containers that run cloud-native applications, Kubernetes is the most popular open source container orchestration platform that makes cluster management easy. This workshop adopts a practical approach to get you acquainted with the Kubernetes environment and its applications. Starting with an introduction to the fundamentals of Kubernetes, you’ll install and set up your Kubernetes environment. You’ll understand how to write YAML files and deploy your first simple web application container using Pod. You’ll then assign human-friendly names to Pods, explore various Kubernetes entities and functions, and discover when to use them. As you work through the chapters, this Kubernetes book will show you how you can make full-scale use of Kubernetes by applying a variety of techniques for designing components and deploying clusters. You’ll also get to grips with security policies for limiting access to certain functions inside the cluster. Toward the end of the book, you’ll get a rundown of Kubernetes advanced features for building your own controller and upgrading to a Kubernetes cluster without downtime. By the end of this workshop, you’ll be able to manage containers and run cloud-based applications efficiently using Kubernetes.

Summary

Over the course of this chapter, we have applied our skills to be able to leverage StatefulSets in our example application. We have looked at how to think about running stateful portions of our software programmatically and how to refactor applications to leverage that change in state persistence. Finally, we learned how to create and run Kubernetes StatefulSets that will allow us to run stateful components in our cluster and make guarantees about how that workload will be run.

Being equipped with the skills needed to manage stateful components on our Kubernetes cluster is a major step in being able to operate effectively in many real-world applications that you are likely to come across.

In the next chapter, we're going to talk more about data-driven application orchestration with the use of Metrics Server, HorizontalPodAutoscalers, and ClusterAutoscaler. We will learn how these objects help us respond to varying levels of demand on our application running on a...
