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.

Enabling Azure AD integration in your AKS cluster

In this section, you will update your existing cluster to include Azure AD integration. You will do this using the Azure portal:

Note

Once a cluster has been integrated with Azure AD, this functionality cannot be disabled.

  1. To start, you will need an Azure AD group. You will later give admin privileges for your AKS cluster to this group. To create this group, search for azure active directory in the Azure search bar:
    Searching for Azure Active Directory in the Azure search bar

    Figure 8.2: Searching for azure active directory in the Azure search bar

  2. In the left pane, select Groups, which will bring you to the All groups screen. Click + New Group, as shown in Figure 8.3:
    In the group pane, clicking the +New group button to create a new Azure AD group

  3. On the resulting page, create a security group and give it a name and description. Select your user as the owner and a member of this group. Click the Create button on the screen:
