Hands-on Kubernetes on Azure, Third Edition - Third Edition

By: Nills Franssens, Shivakumar Gopalakrishnan, Gunther Lenz

Overview of this book

Containers and Kubernetes containers facilitate cloud deployments and application development by enabling efficient versioning with improved security and portability. With updated chapters on role-based access control, pod identity, storing secrets, and network security in AKS, this third edition begins by introducing you to containers, Kubernetes, and Azure Kubernetes Service (AKS), and guides you through deploying an AKS cluster in different ways. You will then delve into the specifics of Kubernetes 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 applications and clusters. As you advance, you'll learn how to overcome common challenges in AKS and secure your applications with HTTPS. You will also learn how to secure your clusters and applications in a dedicated section on security. In the final section, you’ll learn about advanced integrations, which give you the ability to create Azure databases and run serverless functions on AKS as well as the ability to integrate AKS with a continuous integration and continuous delivery (CI/CD) pipeline using GitHub Actions. By the end of this Kubernetes book, you will be proficient in deploying containerized workloads on Microsoft Azure with minimal management overhead.

Installing ASO on your cluster

To install ASO on your cluster, you will need a cluster. At the end of the previous chapter, you deleted your cluster, so you will create a new one here. After that, you will need to create a managed identity and Key Vault. Both are best practices when setting up ASO, which is why this chapter will explain how to set up ASO this way. After the creation of these resources, you need to ensure that cert-manager is set up in your cluster. Once that is confirmed, you can install ASO using a Helm chart.

Let's start with the first step, creating a new AKS cluster.

Creating a new AKS cluster

Since you deleted your cluster at the end of the previous chapter, let's start by creating a new cluster. You can do all these steps using Cloud Shell. Let's get started:

  1. First, you will create a new cluster. Since you will be making use of pod identities for the authorization of ASO, you will also enable the pod identity add-on on this new...
