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.

Defining new objects

Once you install Tekton Triggers into your cluster, you will have access to three new objects. These objects will then be used to create your triggers and automate your pipeline's final part. The following figure describes the flow that happens when a trigger is started:

Figure 10.2 – Tekton trigger flow

In this section, you will learn more about each of these components.

Trigger templates

A TriggerTemplate is a new primitive that will be available to you once you've installed Tekton Triggers. The main goal of the trigger template is to be a template for the resources that the trigger will create.

Trigger templates are to Tekton triggers what pipelines are to pipeline runs. While the templates don't do any work, they describe what pipeline should be triggered and the parameters to pass to that pipeline.

Parameters for the trigger templates are similarly passed to the object, as is the case with pipelines...
