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

11. Build Your Own HA Cluster

Overview

In this chapter, we will learn how Kubernetes enables us to deploy infrastructure with remarkable resilience and how to set up a high-availability Kubernetes cluster in the AWS cloud. This chapter will help you understand what enables Kubernetes to be used for highly available deployments and, in turn, enable you to make the right choices while architecting a production environment for your use case. By the end of the chapter, you will be able to set up a suitable cluster infrastructure on AWS to support your highly available (HA) Kubernetes cluster. You will also be able to deploy an application in a production environment.
