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 Advanced Cluster Security installation

The installation process of ACS is similar to what you have seen in the last chapter with ACM: through an Operator. However, you can also install it using Helm charts or the roxctl CLI. In this book, we will use the Operator installation; if you want more information about the Helm or roxctl installation process, refer to the official documentation. You can find links to the official documentation in the Further reading section of this chapter.

To install ACS using the operator, proceed as follows.


  1. You will need access to an OpenShift cluster with cluster-admin permissions.

Operator installation

Follow the next steps to get the ACS operator ready for use:.

  1. Access the OpenShift Web Console using the Administrator’s perspective.
  2. Navigate to the Operators | OperatorHub menu item.
