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.

7. Monitoring the AKS cluster and the application

Now that you know how to deploy applications on an AKS cluster, let's focus on how you can ensure that your cluster and applications remain available. In this chapter, you will learn how to monitor your cluster and the applications running on it. You'll explore how Kubernetes makes sure that your applications are running reliably using readiness and liveness probes.

You will also learn how AKS Diagnostics and Azure Monitor are used, and how they are integrated within the Azure portal. You will see how you can use AKS Diagnostics to monitor the status of the cluster itself, and how Azure Monitor helps monitor the pods on the cluster and allows you to get access to the logs of the pods at scale.

In brief, the following topics will be covered in this chapter:

  • Monitoring and debugging applications using kubectl
  • Reviewing metrics reported by Kubernetes
  • Reviewing metrics from Azure Monitor
