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.

Creating a Tekton pipeline from scratch

In this section, we will create a Tekton pipeline from scratch so that we can learn from it. We are going to use a sample from our GitHub repository: To practice the concepts we will cover here, fork this repository to your GitHub account and follow the instructions provided in this chapter.

The pipeline that we will work on is simple but helpful. It will consist of the following tasks:

Figure 9.9 – Build and deploy pipeline

In the next few sections, you will learn how to use Tasks, TaksRuns, Pipelines, and PipelineRuns, which are Tekton’s main objects.


To create this pipeline, you need to understand the foundational concept of a task. As we mentioned previously, a task provides a set of structured steps for performing a certain action, such as cloning a GitHub repository or building source code. Now, let’...
