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.

Preface

Kubernetes has taken the world by storm, becoming the standard infrastructure for DevOps teams to develop, test, and run applications. Most enterprises are either running it already, or are planning to run it in the next year. A look at job postings on any of the major job sites shows that just about every big-name company has Kubernetes positions open. The fast rate of adoption has led to Kubernetes-related positions growing by over 2,000% in the last 4 years.

One common problem that companies are struggling to address is the lack of enterprise Kubernetes knowledge. Since the technology is relatively new, and even newer for production workloads, companies have had issues trying to build teams to run clusters reliably. Finding people with basic Kubernetes skills is becoming easier, but finding people with knowledge on topics that are required for enterprise clusters is still a challenge.
