Kubernetes and Docker - An Enterprise Guide

By: Scott Surovich, Marc Boorshtein

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 12: Auditing using Falco and EFK

Bad people do bad things.

Good people do bad things.

Accidents happen.

Each of the preceding statements has one thing in common: when any one of them occurs, you need to find out what happened.

Too often, auditing is considered only when we think of some form of attack. While we certainly require auditing to find "bad people", we also need to audit everyday standard system interactions.

Kubernetes includes logs for most of the important system events that you will need to audit, but it doesn't include everything. As we discussed in previous chapters, all API interactions will be logged by the system, which includes the majority of events you need to audit. However, there are tasks that users execute that will not go through the API server and may go undetected if you are relying on API logs for all of your auditing.

There are tools to address the gaps in the native logging functionality. Open source projects...
