Kubernetes and Docker - An Enterprise Guide

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.

Deploying Falco

We have included a script to deploy Falco, called, in the GitHub repository in the chapter12 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 a modified DaemonSet installation from the book's GitHub repository.

To deploy Falco using the included script, execute the script from within the chapter12 folder by executing ./ We have also included a script called in the same directory that will remove Falco from the cluster.

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 in two sections:

In Section 1, it creates a Falco probe and performs the following steps:

  1. Installs Go using apt
  2. Pulls Falco's driverkit...
