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.

Provisioning and managing multiple clusters

We haven’t touched so far on the hybrid or multi-cluster side of the house. This is what we are going to add now: deployment into multiple remote clusters. To do so, we are going to use Advanced Cluster Management to provision new clusters and also help us to deploy the application in them.

Provisioning new clusters

We are going to use AWS to host two new clusters that will be used as remote clusters to exercise our pipeline. For the sake of saving resources, we are going to use single node clusters, so we don’t need to get the cost of many servers for this exercise. If you already have clusters available, you can alternatively import the existing clusters, instead of provisioning new ones. You can find, in the Further reading section of this chapter, a link that contains instructions about how to import a cluster on Advanced Cluster Management.

To provision a single node cluster using ACM, you need to add the AWS credentials...
