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.

Analyzing configuration using Azure Secure Score

In the previous section, you created several workloads that are purposefully misconfigured. In this section, you'll review the recommendations in Azure Security Center related to these workloads.

Note

It can take up to 30 minutes after the workloads have been created for recommendations and alerts to show up.

  1. After you have created the offending workloads, you will get security recommendations in Azure Security Center. To start, click on Secure Score in the left-hand navigation within Azure Security Center. This will show you a pane similar to Figure 13.13:
    Checking your Secure Score in Azure Security Center after creating offending workloads

    Figure 13.13: Secure Score in Azure Security Center

    What you see here is a summary of the security posture of your environment. In the example shown in Figure 13.13, you see that the overall secure score was 32%. If you manage multiple Azure subscriptions, this view can give you a quick bird's-eye view of the security configuration of your environment.
