Hands-on Kubernetes on Azure, Third Edition - Third Edition

By: Nills Franssens, Shivakumar Gopalakrishnan, Gunther Lenz

Overview of this book

Containers and Kubernetes containers facilitate cloud deployments and application development by enabling efficient versioning with improved security and portability. With updated chapters on role-based access control, pod identity, storing secrets, and network security in AKS, this third edition begins by introducing you to containers, Kubernetes, and Azure Kubernetes Service (AKS), and guides you through deploying an AKS cluster in different ways. You will then delve into the specifics of Kubernetes 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 applications and clusters. As you advance, you'll learn how to overcome common challenges in AKS and secure your applications with HTTPS. You will also learn how to secure your clusters and applications in a dedicated section on security. In the final section, you’ll learn about advanced integrations, which give you the ability to create Azure databases and run serverless functions on AKS as well as the ability to integrate AKS with a continuous integration and continuous delivery (CI/CD) pipeline using GitHub Actions. By the end of this Kubernetes book, you will be proficient in deploying containerized workloads on Microsoft Azure with minimal management overhead.

Various functions platforms

Functions platforms, such as Azure Functions, AWS Lambda, and Google Cloud Functions, have gained tremendous popularity. The ability to run code without the need to manage servers and having virtually limitless scale is very popular. The downside of using the functions implementation of a cloud provider is that you are locked into the cloud provider's infrastructure and their programming model. Also, you can only run your functions in the public cloud and not in your own datacenter.

A number of open-source functions frameworks have been launched to solve these downsides. There are a number of popular frameworks that can be run on Kubernetes:

  • Knative (https://cloud.google.com/knative/): Knative is a serverless platform written in the Go language and developed by Google. You can run Knative functions either fully managed on Google Cloud or on your own Kubernetes cluster.
  • OpenFaaS (https://www.openfaas.com/): OpenFaaS is a serverless framework...
