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.

Deploying Red Hat Quay using the Quay Operator

There are different ways to deploy Quay, as you can see in the product’s official documentation link that you’ll find in the Further reading section of this chapter. For didactical reasons, we decided to deploy it using the Quay Operator with fully-managed components – a comfortable way to start using Quay.

Some prerequisites are necessary to install Quay as an enterprise container registry.

Prerequisites

The prerequisites to install Quay using the Operator are as follows:

  • An OpenShift cluster with a privileged account to deploy and set up Quay.
  • Object storage: The supported object storage is Red Hat OpenShift Data Foundation, AWS S3, Google Cloud Storage, Azure Storage, Ceph/RadosGW Storage/Hitachi HCP storage, Swift storage, and NooBaa.
  • Cluster capacity to host the following services:
    • PostgreSQL or MySQL database. PostgreSQL is preferred due to enhanced features for Clair security scanning...
