The Kubernetes Workshop

By: Zachary Arnold, Sahil Dua, Wei Huang, Faisal Masood, Mélony Qin, Mohammed Abu Taleb

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

12. Your Application and HA

Overview

In this chapter, we will explore Kubernetes cluster life cycle management through the use of Terraform and Amazon Elastic Kubernetes Service (EKS). We will also deploy an application and learn some principles to make applications better suited to the Kubernetes environment.

This chapter will walk you through using Terraform to create a fully functioning, highly available Kubernetes environment. You will deploy an application to the cluster and modify its functionality to make it suitable for a highly available environment. We will also learn how to get traffic from the internet to an application running in a cluster by using a Kubernetes ingress resource.
