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 used Minikube to provision a single-node Kubernetes cluster and gave a high-level overview of Kubernetes' core components, as well as its key design rationale. After that, we migrated an existing Docker container to Kubernetes and explored some basic Kubernetes API objects, such as pods, Services, and Deployments. Lastly, we intentionally broke a Kubernetes cluster and restored it one component at a time, which allowed us to understand how the different Kubernetes components work together to get a pod up and running on a node.

Throughout this chapter, we have used kubectl to manage our cluster. We provided a quick introduction to this tool, but in the following chapter, we will take a closer look at this powerful tool and explore the various ways in which we can use it.
