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.

Kubernetes on Azure (AKS)

Installing and maintaining Kubernetes clusters correctly and securely is hard. Thankfully, all the major cloud providers such as Google Cloud Platform (GCP) (of course, considering Kubernetes was founded in Google), AWS, and Azure facilitate installing and maintaining clusters. You will learn how to navigate through Azure Portal and launch your own cluster and a sample application. And all of the above from your browser.

The following topics will be covered in this chapter:

  • Navigating Azure Portal
  • Launching your cluster
  • Starting your first application
