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.

Metrics reported from Azure Monitor

The Azure portal shows many of the metrics that you would like to see combined with authorization, as only personnel with access to the portal can see these metrics.

AKS Insights

The Insights section of the AKS blade provides most of the metrics you need to know about your cluster. It also has the ability to drill down to the container level. You can also see the logs of the container.

Kubernetes makes metrics available but doesn't store them. Azure Monitor can be used to store these metrics and make them available to query over time. To collect the relevant metrics and logs into Insights, Azure connects to the Kubernetes API to collect the metrics and then stores them in Azure Monitor.

Note

Logs of a container could contain sensitive information. Therefore, the rights to review logs should be controlled and audited.

Let's explore the Insights tab of the AKS blade. We'll start with the cluster metrics.
