Hands-On Kubernetes on Azure

By: Shivakumar Gopalakrishnan, Gunther Lenz

Overview of this book

Microsoft is now one of the most significant contributors to Kubernetes open source projects. Kubernetes helps to create, configure, and manage a cluster of virtual machines that are preconfigured to run containerized applications. This book will be your guide to performing successful container orchestration and deployment of Kubernetes clusters on Azure. You will get started by learning how to deploy and manage highly scalable applications, along with understanding how to set up a production-ready Kubernetes cluster on Azure. As you advance, you will learn how to reduce the complexity and operational overheads of managing a Kubernetes cluster on Azure. By the end of this book, you will not only be capable of deploying and managing Kubernetes clusters on Azure with ease, but also have the knowledge of best practices for working with advanced AKS concepts for complex systems.

Commands for monitoring applications

Monitoring deployed applications on AKS along with monitoring Kubernetes health is essential to provide reliable service to your customers. There are two primary use cases for monitoring:

  • Debugging applications (used mostly when deploying/upgrading apps)
  • On-going monitoring to get alerts if something is not behaving as expected

We will handle the first use case of debugging when deploying/upgrading applications. The same methodology also applies for debugging running applications for which the commands are as follows:

kubectl get xxx
kubectl logs xxx

Before we start, we are going to have a clean start with our guestbook example.

If you have guestbook already running in your cluster, delete it by running the following command on the Azure Cloud Shell:

kubectl delete -f guestbook-all-in-one.yaml

Recreate the guestbook again using the following...
