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.

Deploying Azure Database for MySQL using ASO

In the previous section, you deployed ASO on your Kubernetes cluster. This means that now you can use the Kubernetes API to deploy Azure resources. In this section, you will create a MySQL database running on the Azure Database for MySQL service using YAML files that you will submit to Kubernetes using kubectl. Let's get started:

  1. First, you need to create a resource group. The code for the resource group definition is also available in the code samples with this chapter. Create this file and save it as rg.yaml:
    apiVersion: azure.microsoft.com/v1alpha1
    kind: ResourceGroup
    metadata:
      name: aso-resources
    spec:
      location: <cluster location>

    As you can see in the code for the resource, apiVersion refers to azure.microsoft.com and kind is ResourceGroup. Furthermore, you provide the details for the resource group, being its name and its location. Make sure to change location to the location of your cluster...
