Hands-On Kubernetes on Azure - Second Edition

By: Nills Franssens, Shivakumar Gopalakrishnan, Gunther Lenz

Overview of this book

From managing versioning efficiently to improving security and portability, technologies such as Kubernetes and Docker have greatly helped cloud deployments and application development. Starting with an introduction to Docker, Kubernetes, and Azure Kubernetes Service (AKS), this book will guide you through deploying an AKS cluster in different ways. You’ll then explore the Azure portal by deploying a sample guestbook application on AKS and installing complex Kubernetes apps using Helm. With the help of real-world examples, you'll also get to grips with scaling your application and cluster. As you advance, you'll understand how to overcome common challenges in AKS and secure your application with HTTPS and Azure AD (Active Directory). Finally, you’ll explore serverless functions such as HTTP triggered Azure functions and queue triggered functions. By the end of this Kubernetes book, you’ll be well-versed with the fundamentals of Azure Kubernetes Service and be able to deploy containerized workloads on Microsoft Azure with minimal management overhead.

Summary

In this chapter, we deployed two applications. We started the chapter by deploying the guestbook application. During that deployment, we looked into the details of Pods, ReplicaSets, and deployments. We also used dynamic configuration using ConfigMaps. Finally, we looked into how services are used to route traffic to the deployed applications.

The second application we deployed was a WordPress application. We deployed it via the Helm package manager. As part of this deployment, PVCs were used, and we explored how these were used in the system.

In the next chapter, we will look into scaling applications and the cluster itself. We will first look at the manual and automatic scaling of the application, and afterward, we'll look at the manual and automatic scaling of the cluster itself. Finally, we will explain different ways in which applications can be updated on Kubernetes.
