Discover best practices for designing and scaling robust OpenShift clusters’ architecture for different workloads Manage multiple clusters on-premise or in the cloud using multi-cluster management tools to keep them secure and compliant Implement multi-cluster CI/CD on OpenShift using GitOps Key Features Discover best practices to design robust OpenShift architecture and scale them to different workloads Understand the minimal collection of topics you should consider in your container security strategy Implement multi-cluster CI/CD on OpenShift using GitOps Book DescriptionFor IT professionals working with Red Hat OpenShift Container Platform, the key to maximizing efficiency is understanding the powerful and resilient options to maintain the software development platform with minimal effort. OpenShift Multi-Cluster Management Handbook is a deep dive into the technology, containing knowledge essential for anyone who wants to work with OpenShift. This book starts by covering the architectural concepts and definitions necessary for deploying OpenShift clusters. It then takes you through designing Red Hat OpenShift for hybrid and multi-cloud infrastructure, showing you different approaches for multiple environments (from on-premises to cloud providers). As you advance, you’ll learn container security strategies to protect pipelines, data, and infrastructure on each layer. You’ll also discover tips for critical decision making once you understand the importance of designing a comprehensive project considering all aspects of an architecture that will allow the solution to scale as your application requires. By the end of this OpenShift book, you’ll know how to design a comprehensive Red Hat OpenShift cluster architecture, deploy it, and effectively manage your enterprise-grade clusters and other critical components using tools in OpenShift Plus.What you will learn Understand the important aspects of OpenShift cluster architecture Design your infrastructure to run across hybrid clouds Define the best strategy for multitenancy on OpenShift Discover efficient troubleshooting strategies with OpenShift Build and deploy your applications using OpenShift Pipelines (Tekton) Work with ArgoCD to deploy your applications using GitOps practices Monitor your clusters’ security using Red Hat Advanced Cluster Security Who this book is for This book is for a wide range of IT professionals using or looking to use OpenShift with a hybrid/multi-cloud approach. In this book, IT architects will find practical guidance on OpenShift clusters’ architecture, while Sysadmins, SREs, and IT operators will learn more about OpenShift deployment, troubleshooting, networking, security, and tools to manage multiple clusters from a single pane. For DevOps engineers, this book covers CI/CD strategies for multiple clusters using GitOps. Equipped with just basic knowledge of containerization and Kubernetes, you’re ready to get started.
OpenShift GitOps with Argo CD
"OpenShift GitOps with Argo CD" OpenShift GitOps with Argo CD is your definitive guide to mastering the convergence of GitOps methodology, Red Hat OpenShift, and the powerful automation capabilities of Argo CD. This comprehensive resource brings you from foundational principles—such as declarative desired state management, immutable infrastructure, and the core architectural tenets of OpenShift—to advanced topics including multi-tenancy, integrated networking, operator frameworks, and enterprise-grade access control. Through detailed explorations and actionable insights, you’ll learn to establish robust, secure, and scalable environments for modern Kubernetes operations. Delving deeply into Argo CD fundamentals, the book examines automation workflows, application CRs, health management, and self-healing strategies, all essential for orchestrating continuous delivery in today’s dynamic enterprise settings. Readers are guided through the nuances of deploying and operating Argo CD on OpenShift, including installation via OpenShift GitOps Operator, enforcing least-privilege security, integrating with OpenShift Pipelines, managing custom resources, and safe upgrade practices. Special attention is given to multi-tenant deployments and the effective handling of sensitive data and secrets for real-world production needs. For those scaling operations beyond the basics, the book covers advanced application lifecycle management, secure policy enforcement with OPA and Gatekeeper, cloud-native observability using Prometheus and EFK/ELK, enterprise-scale multi-cluster management, and proven approaches for cost and performance optimization. You’ll also explore emerging paradigms, from progressive delivery and service mesh integrations to the evolving standards shaping the GitOps ecosystem. OpenShift GitOps with Argo CD equips both engineers and architects with the critical knowledge and best practices required to deliver secure, resilient, and continuous software innovation across Kubernetes platforms.
Architecting and Operating OpenShift Clusters
Design and architect resilient OpenShift clusters and gain a keen understanding of how hundreds of projects are integrated into a powerful solution. While there are many OpenShift resources available for developers, this book focuses on the key elements of infrastructure and operations that teams need when looking to integrate and maintain this platform. You'll review important concepts, such as repeatable deployment techniques, advanced OpenShift RBAC capabilities, monitoring clusters, and integrating with external services. You'll also see how to run specialized workloads in OpenShift and how to deploy non-web based applications on the platform, all designed to help cultivate best practices as your organization continue evolve in microservices architectures. OpenShift has become the main enterprise Kubernetes distribution and its market penetration continues to growth at rapid rate. While OpenShift’s documentation provides a great list of configurationoptions to work with the platform, it can be a daunting task to wade through. Architecting and Operating OpenShift Clusters breaks this content down into clear and useful concepts to provide you with a solid understanding of the OpenShift internal architecture. What You'll Learn Operate high availability in muti-tenant OCP clusters Understand OpenShift SDN models, capabilities, and storage classes Integrate OCP with existing data center capabilities and CI/CD pipelines Support advanced capabilities like: Istio, Multus, Kubernetes Operators, hybrid deployments Who This Book Is For Cloud architects, OpenShift cluster administrators, and teams supporting developers in OpenShift environments who have a basic understanding of this platform and microservices architectures.
