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.
Table of Contents (23 chapters)
Part 1 – Design Architectures for Red Hat OpenShift
Part 2 – Leverage Enterprise Products with Red Hat OpenShift
Part 3 – Multi-Cluster CI/CD on OpenShift Using GitOps
Part 4 – A Taste of Multi-Cluster Implementation and Security Compliance
Part 5 – Continuous Learning


In this chapter, you learned about various concepts related to GitOps. You also learned about Argo CD and how to install it on OpenShift and use it. You also built and deployed a sample application to three different namespaces to simulate the development, QA, and production environments. Finally, you learned that deploying to the local or external cluster is a similar process – you only need to change the destination server field.

Argo CD allows you to establish an efficient and robust application delivery model using GitOps, in which you ensure consistency, auditable changes, and a secure process, no matter where you are deploying your applications. And the best part is that there is no additional cost to use it since it is included in Red Hat OpenShift’s subscription. That said, if you are deploying containerized applications on OpenShift, I strongly recommend that you try OpenShift GitOps and use the concepts we explored in this chapter.
