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).

Deploying Falco

We have included a script to deploy Falco, called install-falco.sh, in the GitHub repository in the chapter10 folder.

The two most popular methods of deploying Falco to a Kubernetes cluster are using the official Helm chart or a DaemonSet manifest from the Falco repo. For the purposes of this module, we will deploy Falco using Helm and a custom values.yaml from the book's GitHub repository.

To deploy Falco using the included script, execute the script from within the chapter10 folder by executing ./install-falco.sh.

The steps that the script performs are detailed in the following list and will be explained in additional detail in this section.

The script executes the following tasks:

  1. Creates the Falco namespace
  2. Adds the charts from the falcosecurity.github.io/charts repository
  3. Installs Falco using Helm in the falco namespace using the custom values file along with the custom rules file for our NGINX example
