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.

what you will learn
Create a multinode Kubernetes cluster using kind
Implement Ingress, MetalLB, and ExternalDNS
Configure a cluster OIDC using impersonation
Map enterprise authorization to Kubernetes
Secure clusters using PSPs and OPA
Enhance auditing using Falco and EFK
Back up your workload for disaster recovery and cluster migration
Deploy to a platform using Tekton, GitLab, and ArgoCD
key features
Find out how to add enterprise features to a Kubernetes cluster with theory and exercises to guide you * Understand advanced topics including load balancing, externalDNS, IDP integration, security, auditing, backup, and CI/CD * Create development clusters for unique testing requirements, including running multiple clusters on a single server to simulate an enterprise environment
approach
Each chapter will have the reader implement the solution on their own Kubernetes cluster running Kind (scripts are provided to install all required packages). Rather than simply provide steps to implement each solution like a cookbook, each chapter contains an equal amount of theory to provide the details to understand each component being installed.
audience
This book is for anyone interested in DevOps, containerization, and going beyond basic Kubernetes cluster deployments. DevOps engineers, developers, and system administrators looking to enhance their IT career paths will also find this book helpful. Although some prior experience with Docker and Kubernetes is recommended, this book includes a Kubernetes bootcamp that provides a description of Kubernetes objects to help you if you are new to the topic or need a refresher.
short description
Complete with practical examples and explanations to address running Kubernetes in an enterprise, this book guides you to integrating Kubernetes clusters with load-balancers, external name resolution for services, OIDC using an enterprise directory, Kubernetes impersonation, security using PSPs and OPA, advanced auditing and reporting, backing up workloads, and provisioning a platform.
