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.

Technical requirements

As we mentioned previously, OpenShift Pipelines is a Kubernetes native application and, as such, is a lightweight tool that uses Custom Resource Definitions (CRDs) to extend the OpenShift API’s functionalities. In the upcoming sections, you will see that the installation is fairly simple and only involves installing an operator – a “Next, Next, Finish” sort of experience. To be able to install it and run the exercises in this chapter, you only need an OpenShift cluster with the following available resources:

  • 2 vCPUs
  • 2 GB of RAM

If you don’t have an OpenShift cluster available to use, we recommend that you try CRC to spin up a cluster locally on your machine. To use CRC, you need to have the following system requirements on your workstation:

  • 4 physical CPU cores (AMD64 or Intel 64)
  • 9 GB of free memory
  • 35 GB of storage space
  • One of the following operating systems:
    • Windows (Windows 10 Fall...
