Book Description

For IT professionals working with Red Hat OpenShift Container Platform, the key to maximize 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 critical knowledge essential for anyone who wants to work with OpenShift.

This book starts by covering the most important architectural concepts and definitions necessary for deploying OpenShift clusters. It then takes you through designing Red Hat OpenShift for the hybrid or 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 have gained the knowledge 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 clusters’ 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
