Overview of this book

Tekton is a powerful yet flexible Kubernetes-native open source framework for creating continuous integration and continuous delivery (CI/CD) systems. It enables you to build, test, and deploy across multiple cloud providers or on-premise systems. Building CI/CD Systems Using Tekton covers everything you need to know to start building your pipeline and automating application delivery in a cloud-native environment. Using a hands-on approach, you will learn about the basic building blocks, such as tasks, pipelines, and workspaces, which you can use to compose your CI/CD pipelines. As you progress, you will understand how to use these Tekton objects in conjunction with Tekton Triggers to automate the delivery of your application in a Kubernetes cluster. By the end of this book, you will have learned how to compose Tekton Pipelines and use them with Tekton Triggers to build powerful CI/CD systems.

Using task results in pipelines

In the previous chapter, you've seen how to use results inside tasks to share information across steps. You can also use the same results to share limited information across tasks.

For the last example in this chapter, you will rewrite the dice-roll task to produce a result instead of echoing the result. This randomly generated number will then be picked up by the logger task to be displayed:

  1. Start by creating a file named dice-results.yaml in which you will create the base of your new task named dice-roll-result:
    apiVersion: tekton.dev/v1beta1 
    kind: Task 
    metadata: 
      name: dice-roll-result 
    spec: 
  2. Just like you did in the previous version of the die-roll task, add a parameter with a default value of "6":
    params: 
       - name: sides 
         description: Number of sides to the dice 
         default: "6" 
         type: string...
