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.

Reusing tasks in the context of a pipeline

In the last chapter, you saw how to make tasks reusable by using parameters. You also saw how you can set the values for those parameters from a pipeline. Using those parameters, you can use a given task in multiple pipelines, and you can even use a given task inside a single pipeline. This is what you will do here:

  1. Start with a new file called log-task.yaml. Here, create a new task called logger:
    apiVersion: tekton.dev/v1beta1 
    kind: Task 
    metadata: 
      name: logger 
    spec: 
  2. This task will need a parameter. You can give it the name text. This will be a parameter of the string type:
      params: 
       - name: text 
         type: string 
  3. For the steps object, you will have a single step that logs the date and time followed by the text to be logged:
      steps: 
       - name: log 
         image: registry.access.redhat.com/ubi8/ubi-minimal...
