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

Introduction

We ended the previous chapter by providing a brief and abstract introduction to Kubernetes, as well as some of its advantages. In this chapter, we will provide you with a much more concrete high-level understanding of how Kubernetes works. First, we will walk you through how to install Minikube, which is a handy tool that creates a single-node cluster and provides a convenient learning environment for Kubernetes. Then, we will take a 10,000-foot overview of all the components, including their responsibilities and how they interact with each other. After that, we will migrate the Docker application that we built in the previous chapter to Kubernetes and illustrate how it can enjoy the benefits afforded by Kubernetes, such as creating multiple replicas, and version updates. Finally, we will explain how the application responds to external and internal traffic.

Having an overview of Kubernetes is important before we dive deeper into the different aspects of it so that...
