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.

Other considerations

Finally, there are a few more things that you should also consider during the design phase of your OpenShift cluster.

SSL certificates

OpenShift uses SSL for all cluster communication. During the platform installation, self-signed certificates are generated; however, it is possible to replace the API and ingress certificates. At this point, you only need to know that this is possible; later in this book, you will see how to do it.

IdPs

OpenShift is deployed using a temporary kubeadmin user. It is highly recommended you configure new IdPs to allow users to log in to the platform using a convenient and safe authentication method. There are several supported IdPs with OpenShift; here is a current list of supported options (at the time of writing this book):

To wrap up this chapter and give you a quick reference guide, look at the OpenShift architectural checklists we provide next.
