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.

We have seen in this chapter some of the things you may consider to have secure OpenShift clusters. While OpenShift is considered a secure platform based on Kubernetes, how you manage it, of course, matters a lot. Consider establishing policies for access control, certificates, container and network isolation, development, and CI/CD pipelines.

A secure platform starts with proper planning to define and implement efficient policies to control what is being developed and deployed into the platform, protect it against unnecessary risks, and—finally—isolate workloads and networks as much as possible to mitigate the impacts that a breach could have on the environment. In Chapter 11, OpenShift Multi-Cluster GitOps and Management, you will see how to use Advanced Cluster Management to apply policies at scale to several clusters and make sure that all of them are compliant and safe, no matter where they are running.

In the next chapter, we will explore how to work...
