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.

Events and serverless functions

Serverless functions mainly use events to trigger their invocation. While the following invocation is useful for testing and debugging purposes, it is not really useful for other purposes. Serverless functions excel when they are run on demand and, in general, as part of some automation triggered by events. Calling them manually, as we are doing in the following code, is useful only for testing and debugging purposes:

kubeless function call hello --data 'Hello world!' -n serverless

To be really useful, we need the ability to trigger it through events. One of the easiest ways to integrate our serverless functions with events is to use Azure Event Hubs. In this section, we will integrate Azure Event Hubs with our serverless functions. We will be using Azure Functions to call our serverless function.

There are multiple ways that a function...
