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.

Section 4: Integrating with Azure managed services

So far in the book, you have run multiple applications on top of Azure Kubernetes Service (AKS). The applications were always self-contained, meaning the full application was able to run in its entirety on top of AKS. There are certain advantages of running a full application on top of AKS. You gain application portability since you can move that application to any other Kubernetes cluster with little friction. You also have full control over the end-to-end application.

With great control comes great responsibility. There are certain advantages to offloading parts of your application to one of the PaaS services that Azure offers. For example, by offloading your database to a managed PaaS service, you no longer need to take care of updating the database service, backups are automatically performed for you, and a lot of logging and monitoring is done out of the box.

In the coming chapters, you will learn more about multiple...
