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 ACM installation

In this section, we will guide you through the installation and configuration of ACM.

Important Note

It is important to consider that ACM uses the compute, memory, and storage resources of the hub cluster, thus it is recommended to have a dedicated cluster to be the hub for ACM, avoiding concurrent workloads and resource usage. This is recommended but not required; you can run ACM in any OpenShift cluster with enough capacity.

The installation process is simple, similar to what we followed in the last chapters with OpenShift Pipelines and GitOps, as you can see in this section.

Prerequisites

  1. Access to an OpenShift cluster with cluster-admin permissions.

Installation

Follow this process to install Red Hat Advanced Cluster Management:

  1. Access the OpenShift web console using a cluster-admin user.
  2. Navigate to the Operators | OperatorHub menu item.
