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.

Setting up Azure Security Center for Kubernetes

We'll start this chapter by setting up Azure Security Center for Kubernetes. To enable Azure Security Center for Kubernetes, you need to enable Azure Policy for AKS on your cluster. This will enable Azure Security to monitor your workload configuration. To benefit from Azure Defender's threat protection, you will also need to enable Azure Defender for Kubernetes on your subscription.

Let's get started.

  1. Search for your AKS cluster in the Azure search bar, as shown in Figure 13.1:
    Looking for your cluster in the Azure search bar

    Figure 13.1: Looking for your cluster in the Azure search bar

  2. You will now enable Azure Policy for AKS. To enable this, click the Policies button on the left-hand side and on the resulting pane, click on Enable add-on, as shown in Figure 13.2:

    Enabling the add-on will take a couple of minutes to complete. After a while, you should see a message saying that the service is now enabled, as...
