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.

Configuration Management

The Configuration Management feature is a different way to look at policies that are violated, correlating with the various objects that make up the configuration and use of the clusters. Using this feature, you can list all failing policies for all clusters and drill down to inspect all namespaces, deployments, and so on. You may be thinking that the same information can also be found in Violations and Vulnerability Management, and that is true! The same information is also there; however, here, you will find it grouped by clusters’ entities and also displaying summary data of each entity, which will help you to correlate the different entities and learn about the connections among them.

To access this feature, navigate to the Configuration Management menu:
