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.

Things that can crash a cluster

Every time we start learning about some technology, it is common to be twice as careful with the installation, configuration, or adjustment to be as thorough as possible. Sometimes, to achieve these goals related to troubleshooting, performance, and best practices, the reader would turn to multiple expert readings on each of the related topics, or go through the pain of trial and error, which takes a lot of effort to succeed.

OpenShift is a great and disruptive technology, but you will navigate through a puzzle of different aspects related to storage, compute, network, and others. Obviously, in the official documentation—or even in quick internet searches—you will find commands to start from scratch, but in many situations, even with the necessary commands and parameters, it is difficult to navigate from troubleshooting to a solution.

Currently, OpenShift has an automatic recovery system, but this is usually not enough to ensure a...
