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.

OpenShift Troubleshooting, Performance, and Best Practices

The concepts explained in Chapter 5, OpenShift Deployment, provided the foundation for you to initiate your first contact with an OpenShift cluster. In this chapter, we will give some tips on how to perform a health check on a cluster, dive into some root cause analysis (RCA), and also provide details on how to make a cluster run according to some best practices. Our intention with this chapter is to give you some general guidance about troubleshooting, however, it is important you always open a support ticket with Red Hat before making any changes in the platform due to troubleshooting attempts.

This chapter covers the following topics:

  • Things that can crash a cluster
  • Troubleshooting reference guide—how to start
  • Understanding misleading error messages
