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.

Managing clusters using Red Hat ACM

As we mentioned previously, one of the features ACM provides is cluster management. The following is a list of some of the operations you can perform with ACM:

  • Cluster provisioning
  • Import of existing clusters
  • Destroying a cluster
  • Upgrading a cluster
  • Scaling cluster nodes in or out

Check the Further reading section of this chapter to see a link to a complete list of supported operations.

We will not cover how to do all the operations you can perform with ACM in this book, but we will guide you through the process of provisioning a new OpenShift cluster on AWS using ACM, to give you an idea of how easy it is to use the tool.

Cluster provisioning

Currently, in version 2.5, ACM can deploy clusters on AWS, Azure, Google Cloud, VMware vSphere, bare metal, Red Hat OpenStack, and Red Hat Virtualization. To do so, you need to first input the provider credentials to be used by ACM during the provisioning process. The...
