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.

Section 3: Running Kubernetes in the Enterprise

In this last section, we will dive into the add-on components that a cluster requires for the enterprise. The first topic will explain how to integrate identity and access management using an enterprise directory. We will then focus on securing a cluster, starting with how to deploy a secure Kubernetes dashboard, which is commonly viewed as a security issue. Using the dashboard as an example, we will explain how to use an identity provider to secure a cluster using role-based access control (RBAC).

Going beyond basic RBAC, we will then see how to secure a cluster by using Pod Security Policies and Open Policy Agent. Finally, we will expain how to close a commonly overlooked audit point in a cluster, pod-level auditing, by implementing Falco and EFK.

The last part of this section will provide details on how to back up workloads for disaster recovery and cluster migrations. Finally, we will close out the book by creating a new cluster...
