Overview of this book

Containerization has changed the DevOps game completely, with Docker and Kubernetes playing important roles in altering the flow of app creation and deployment. This book will help you acquire the knowledge and tools required to integrate Kubernetes clusters in an enterprise environment. The book begins by introducing you to Docker and Kubernetes fundamentals, including a review of basic Kubernetes objects. You’ll then get to grips with containerization and understand its core functionalities, including how to create ephemeral multinode clusters using kind. As you make progress, you’ll learn about cluster architecture, Kubernetes cluster deployment, and cluster management, and get started with application deployment. Moving on, you’ll find out how to integrate your container to a cloud platform and integrate tools including MetalLB, externalDNS, OpenID connect (OIDC), pod security policies (PSPs), Open Policy Agent (OPA), Falco, and Velero. Finally, you will discover how to deploy an entire platform to the cloud using continuous integration and continuous delivery (CI/CD). By the end of this Kubernetes book, you will have learned how to create development clusters for testing applications and Kubernetes components, and be able to secure and audit a cluster by implementing various open-source solutions including OpenUnison, OPA, Falco, Kibana, and Velero.

Chapter 11: Extending Security Using Open Policy Agent

So far, we have covered Kubernetes' built in authentication and authorization capabilities, which help to secure a cluster. While this will cover most use cases, it doesn't cover all of them. Several security best practices that Kubernetes can't handle are pre-authorizing container registries and ensuring that resource requests are on all Pod objects.

These tasks are left to outside systems and are called dynamic admission controllers. The Open Policy Agent (OPA), and its Kubernetes native sub-project, GateKeeper, are one of the most popular ways to handle these use cases. This chapter will detail the deployment of OPA and GateKeeper, how it's architected, and how to develop policies.

In this chapter, we will cover the following topics:

  • Introduction to validating webhooks
  • What is OPA and how does it work?
  • Using Rego to write policies
  • Enforcing memory constraints
  • Enforcing Pod...
