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).

Summary

In this chapter, we explored the security of the Kubernetes Dashboard in detail. First, we walked through the architecture and how the dashboard passes your identity information on to the API server. We then explored how the dashboard gets compromised, and finally we detailed how to correctly deploy the dashboard securely.

With this knowledge, you can now provide a secured tool to your users. Many users prefer the simplicity of accessing the dashboard via a web browser. Adding multi-factor authentication adds an additional layer of security and peace of mind. When your security team questions the security of the dashboard, you'll have the answers needed to satisfy their concerns.

The previous three chapters focused on the security of the Kubernetes APIs. Next, in Chapter 8, Extending Security Using Open Policy Agent, we'll explore securing the soft underbelly of every Kubernetes deployment, nodes!
