About 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.

Section 1: Docker and Container Fundamentals

In this first section, we will review important Docker and container concepts, and the benefits that Docker provides to developers. After a quick review of Docker, we will move on to how we can add persistent data to a container and how to work with Docker networking to expose containers to the outside world. These basic concepts are essential to fully understanding Kubernetes and understanding how containers run a cluster.

This part of the book comprises the following chapters:

  • Chapter 1, Understanding Docker and Container Essentials
  • Chapter 2, Working with Persistent Data
  • Chapter 3, Understanding Docker Networking
