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.

Use case description

To be a bit closer to what you see in the real world, this time we are going to use a Java application, using Quarkus, which is a great option to build modern, cloud-native applications with Java. Look at the references in the Further reading section of this chapter for more information about Quarkus.

Our application source code was extracted from the Getting started with Quarkus sample; see reference for it in the Further reading section of this chapter. During this chapter, we will create a CI/CD pipeline that will do the following:

  1. Build the application using s2i to generate Java binaries.
  2. Push the container image to Quay.
  3. Run a security scan on the image using Advanced Cluster Security.
  4. Deploy the application on the local cluster using ArgoCD.
  5. Deploy the application on multiple remote clusters using ArgoCD and Advanced Cluster Management.

We are going to use Advanced Cluster Management to make all OpenShift clusters compliant...
