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.

Configuring KinD for OpenID Connect

For our example deployment, we will use a scenario from our customer, FooWidgets.Foowidgets has a Kubernetes cluster that they would like integrated using OIDC. The proposed solution needs to address the following requirements:

  • Kubernetes must use our central authentication system, Active Directory Federation Services.
  • We need to be able map Active Directory groups into our RBAC RoleBinding objects.
  • Users need access to the Kubernetes Dashboard.
  • Users need to be able to use the CLI.
  • All enterprise compliance requirements must be met.

Let's explore each of these in detail and explain how we can address the customer's requirements.

Addressing the requirements

Our enterprise's requirements require multiple moving parts, both inside and outside our cluster. We'll examine each of these components and how they relate to building an authenticated cluster.

Use Active Directory Federation Services...
