Hands-On Kubernetes on Azure - Second Edition

By: Nills Franssens, Shivakumar Gopalakrishnan, Gunther Lenz

Overview of this book

From managing versioning efficiently to improving security and portability, technologies such as Kubernetes and Docker have greatly helped cloud deployments and application development. Starting with an introduction to Docker, Kubernetes, and Azure Kubernetes Service (AKS), this book will guide you through deploying an AKS cluster in different ways. You’ll then explore the Azure portal 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 application and cluster. As you advance, you'll understand how to overcome common challenges in AKS and secure your application with HTTPS and Azure AD (Active Directory). Finally, you’ll explore serverless functions such as HTTP triggered Azure functions and queue triggered functions. By the end of this Kubernetes book, you’ll be well-versed with the fundamentals of Azure Kubernetes Service and be able to deploy 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 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 Azure Monitor is used, and how it is integrated within the Azure portal, as well as how to set up alerts for critical events on your AKS cluster. You will see how you can use Azure Monitor to monitor the status of the cluster itself, the Pods on the cluster and 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
