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 learned how to set up a multi-node Kubernetes platform on AWS using kops in Chapter 11, Build Your Own HA Cluster. In this chapter, you will learn about upgrading the Kubernetes platform to a new version. We will walk you through hands-on examples of the steps that are required to upgrade the Kubernetes platform. These exercises will also equip you with the skills required to maintain a Kubernetes cluster.

Different organizations set up and maintain their Kubernetes clusters in different ways. You saw in Chapter 12, Your Application and HA, that there are numerous ways to set up a cluster. We will present a simple technique to upgrade your cluster and, depending on the cluster you are dealing with, the exact techniques and steps that you will need to take for upgrading may be different, although the basic principles and precautions that we will mention here will be applicable regardless of how you go about upgrading your cluster.
