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.

Setting up Azure and GitHub

In this section, you'll set up the basic infrastructure you'll use to create and run the pipeline that you will build. To host your container images, you need a container registry. You could use a number of container registries, but here you'll create an Azure Container Registry instance because it is well integrated with Azure Kubernetes Service (AKS). After creating the container registry, you will need to link that container registry to your AKS cluster and create a new service principal, and then you'll need to set up a GitHub repository to run the example part of this chapter. Execute the following seven steps to complete this activity:

  1. To start, create a new container registry. In the Azure search bar, look for container registry and click on Container registries, as shown in Figure 15.2:
