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.

12. Connecting an application to an Azure database

In previous chapters, you stored the state of your application in your cluster, either on a Redis cluster or on MariaDB. You might remember that both had some issues when it came to high availability. This chapter will take you through the process of connecting to a MySQL database managed by Azure.

We will discuss the benefits of using a hosted database rather than running StatefulSets on Kubernetes. To create this hosted and managed database, you will make use of Azure Service Operator (ASO). ASO is a way to create Azure resources, such as a managed MySQL database, from within a Kubernetes cluster. In this chapter, you will learn more details about the ASO project, and you will set up and configure ASO on your cluster.

You will then make use of ASO to create a MySQL database in Azure. You will use this managed database as part of a WordPress application. This will show you how you can connect an application...
