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.

Verifying RBAC for a user

To verify that RBAC works as expected, you will sign in to the Azure portal using the newly created user. Go to https://portal.azure.com in a new browser, or an InPrivate window, and sign in with the newly created user. You will be prompted immediately to change your password. This is a security feature in Azure AD to ensure that only that user knows their password:

Prompt asking the user to update their password

Figure 8.19: You will be asked to change your password

Once you have changed your password, you can start testing the different RBAC roles:

  1. You will start this experiment by setting up Cloud Shell for the new user. Launch Cloud Shell and select Bash:
    Selecting Bash as Cloud Shell

  2. In the next dialog box, select Show advanced settings:
    Clicking the Show advanced settings button
