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.

1. Introduction to Docker and Kubernetes

Kubernetes has become the leading standard in container orchestration. Since its inception in 2014, it has gained tremendous popularity. It has been adopted by start-ups as well as major enterprises, and the major public cloud vendors all offer a managed Kubernetes service.

Kubernetes builds upon the success of the Docker container revolution. Docker is both a company and the name of a technology. Docker as a technology is the standard way of creating and running software containers, often called Docker containers. A container itself is a way of packaging software that makes it easy to run that software on any platform, ranging from your laptop to a server in a data center, to a cluster running in the public cloud.

Docker is also the name of the company behind the Docker technology. Although the core technology is open source, the Docker company focuses on reducing complexity for developers through a number of commercial offerings...
