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.

Section 3: Securing your AKS cluster and workloads

Loose lips sink ships is a phrase that describes how easy it can be to jeopardize the security of a Kubernetes-managed cluster (Kubernetes, by the way, is Greek for helmsman, as in the helmsman of a ship). If your cluster is left open with the wrong ports or services exposed, or plain text is used for secrets in application definitions, bad actors can take advantage of this negligent security and do pretty much whatever they want in your cluster.

There are multiple items to consider when securing an Azure Kubernetes Service (AKS) cluster and workloads running on top of it. In this section, you will learn about four ways to secure your cluster and applications. You will learn about role-based access control in Kubernetes and how this can be integrated with Azure Active Directory (Azure AD). After that, you'll learn how to allow your pods to get access to Azure resources such as Blob Storage or Key Vault using an Azure...
