Key Features

• Extensively revised edition to cover the latest updates and new releases along with two new chapters to introduce Istio
• Get a firm command of Kubernetes from a dual perspective of an admin as well as a developer
• Understand advanced topics including load balancing, externalDNS, global load balancing, authentication integration, policy, security, auditing, backup, Istio and CI/CD

Book Description

Kubernetes has taken the world by storm, becoming the standard infrastructure for DevOps teams to develop, test, and run applications. With significant updates in each chapter, this revised edition will help you acquire the knowledge and tools required to integrate Kubernetes clusters in an enterprise environment.

The book introduces you to Docker and Kubernetes fundamentals, including a review of basic Kubernetes objects. You’ll get to grips with containerization and understand its core functionalities such as creating ephemeral multinode clusters using KinD. The book has replaced PodSecurityPolicies (PSP) with OPA/Gatekeeper for PSP-like enforcement. You’ll integrate your container into a cloud platform and tools including MetalLB, externalDNS, OpenID connect (OIDC), Open Policy Agent (OPA), Falco, and Velero. After learning to deploy your core cluster, you’ll learn how to deploy Istio and how to deploy both monolithic applications and microservices into your service mesh. Finally, you will discover how to deploy an entire GitOps platform to Kubernetes using continuous integration and continuous delivery (CI/CD).

What you will learn

• Create a multinode Kubernetes cluster using KinD
• Implement Ingress, MetalLB, ExternalDNS, and the new sandbox project, K8GBConfigure a cluster OIDC and impersonation
• Deploy a monolithic application in Istio service mesh
• Map enterprise authorization to Kubernetes
• Secure clusters using OPA and GateKeeper
• Enhance auditing using Falco and ECK
• Back up your workload for disaster recovery and cluster migration
• Deploy to a GitOps platform using Tekton, GitLab, and ArgoCD
