Overview of this book

For 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 this book covers

Chapter 1, Hybrid Cloud Journey and Strategies, discusses the main challenges of public cloud adoption and explains what OpenShift is, and why it can help to deal with those challenges to achieve success in the business, culture, and technical aspects of hybrid cloud adoption.

Chapter 2, Architecture Overview and Definitions, walks through the main concepts related to Kubernetes and OpenShift architecture to help you decide on the best path you may take.

Chapter 3, Multi-Tenant Considerations, helps you to work with multi-tenancy on OpenShift to provide multiple environments to multiple teams, with proper isolation for every case.

Chapter 4, OpenShift Personas and Skillset, looks at changes that can be made in a company structure to help people adapt to their roles and responsibilities.

Chapter 5, OpenShift Deployment, is a complete hands-on guide to installing and using OpenShift.

Chapter 6, OpenShift Troubleshooting, Performance, and Best Practices, demonstrates some of the most common issues with OpenShift usage.

Chapter 7, OpenShift Network, explores OpenShift’s network layers, such as the Open vSwitch, as well as the north-south and east-west traffic concepts, and the different types of TLS configurations for OpenShift routes.

Chapter 8, OpenShift Security, presents some of the most important concepts of security such as container security, authentication and authorization, identity providers, Role-Based Access Control (RBAC), certificates, etcd encryption, container and network isolation, the Red Hat container catalog for image certification, and vulnerability protection.

Chapter 9, OpenShift Pipelines – Tekton, introduces OpenShift Pipelines, a Kubernetes native CI/CD pipeline tool based on Tekton. This chapter contains the main concepts, the installation process, and a hands-on lab to learn using a practical approach.

Chapter 10, OpenShift GitOps – ArgoCD, expands the deployment capabilities by adding GitOps and ArgoCD. This chapter covers GitOps concepts, OpenShift GitOps installation, and a hands-on lab.

Chapter 11, OpenShift Multi-Cluster GitOps and Management, deep dives into hybrid/multi-cloud concepts and the main concerns about adopting multiple clusters. This chapter describes what Red Hat Advanced Cluster Management is, its installation, and how to use it to manage multiple Kubernetes clusters from a central console.

Chapter 12, OpenShift Multi-Cluster Security, expands the concepts from Chapter 8, OpenShift Security, focusing on multi-cluster security concerns. This chapter covers the Red Hat Advanced Cluster Security tool features, such as risk management, vulnerabilities, violation, policies, compliance, and configuration management, along with installation, configuration, and usage instructions.

Chapter 13, OpenShift Plus – a Multi-Cluster Enterprise Ready Solution, introduces Red Hat Quay as an enterprise image registry option, and it also discusses the benefits of the OpenShift Plus offering as a great option for enterprises looking for consistency and portability in a hybrid/multi-cloud environment.

Chapter 14, Building a Cloud-Native Use Case on a Hybrid Cloud Environment, introduces a complete practical example. This chapter transposes all the concepts in the book using a step-by-step hands-on guide to show how to build and deploy an application using most of the features covered throughout the book: OpenShift Pipelines (Tekton), OpenShift GitOps (ArgoCD), Advanced Cluster Management, Quay, and Advanced Cluster Security.

Chapter 15, What’s Next, offers suggestions for the next steps to take to keep learning and going even deeper into OpenShift through training and certifications.
