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.

Preface

Summary

In this chapter, we have explored various components of pod configuration and learned when to use what. We should now be able to create a pod and choose the right values of various fields in the pod configuration according to the needs of your application. This ability puts us in a position where we can use our strong understanding of this essential, basic building block and extend it to develop a full-fledged application that's deployed reliably.

In the next chapter, we will discuss how we can add labels and arbitrary metadata to pods and use them to identify or search for pods. That will help us to organize our pods as well as choose a subset of them when required.
