Kubernetes – An Enterprise Guide - Second Edition

By: Marc Boorshtein, Scott Surovich

Overview of this book

Kubernetes has taken the world by storm, becoming the standard infrastructure for DevOps teams to develop, test, and run applications. With significant updates in each chapter, this revised edition will help you acquire the knowledge and tools required to integrate Kubernetes clusters in an enterprise environment. The book introduces you to Docker and Kubernetes fundamentals, including a review of basic Kubernetes objects. You’ll get to grips with containerization and understand its core functionalities such as creating ephemeral multinode clusters using KinD. The book has replaced PodSecurityPolicies (PSP) with OPA/Gatekeeper for PSP-like enforcement. You’ll integrate your container into a cloud platform and tools including MetalLB, externalDNS, OpenID connect (OIDC), Open Policy Agent (OPA), Falco, and Velero. After learning to deploy your core cluster, you’ll learn how to deploy Istio and how to deploy both monolithic applications and microservices into your service mesh. Finally, you will discover how to deploy an entire GitOps platform to Kubernetes using continuous integration and continuous delivery (CI/CD).

Introducing DevOPs AI

Our function isn't really an AI function, it's a "dumb" function that only reacts to a certain event and it has no logic to understand if the event should be allowed or not. Our example is only meant to introduce you to using Falcosidekick to increase your security by forwarding events to an external system.

There are no limits to what you can create once events are forwarded – you can forward events to GCP Pub/Sub, and once an event is in GCP you can leverage any of Google's tools to create complex decisions that leverage any of the Google AI tools.

Obviously, AI is an entire series of books by itself, so we decided to stick to a single, static use case. While it's true that AI is much cooler than static checks, you can still create an effective automatic response engine using standard functions.

Now to see this in action!
