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.

Red Hat Container Catalog

Most enterprises, at some point, need to use containers from different sources, either as off-the-shelf products or only as dependencies for workloads. Red Hat has an interesting tool that aims to help you to make sure you use secure containers. The Red Hat Container Catalog is a repository of container images that have been tested and certified by Red Hat and partners, and therefore are trusted images.

As part of the Container Catalog, Red Hat provides the Container Health Index. The Container Health Index is a rating system for container images available in the Red Hat Container Catalog, which goes from Grade A to F, in which Grade A is the most up-to-date image in terms of critical errata. You can find all the grades available and how they are defined at this link: https://access.redhat.com/articles/2803031. This feature helps a lot to assess the security risk you are associated with when using a certain image version.
