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.

OpenShift Multi-Cluster Security

In Chapter 8, OpenShift Security, we discussed some important aspects you may consider for defining and implementing security policies for your OpenShift cluster. We went through aspects such as authentication and authorization, certifications and encryption, container and network isolation, and others. If you haven't gone through that chapter yet, we encourage you to take a look now before reading this one.

Implementing security policies on OpenShift is important, but not really complicated in general – most policies’ configuration is straightforward and well documented. Things become more complicated when you scale your infrastructure to several clusters though. How can you be sure that all the containers that run on top of several clusters are using secure and certified base images? Do you know how compliant all your environments are according to industry and regulatory standards such as PCI and HIPAA? To help you to monitor...
