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.

Sharing data

Because all the steps in a task are actually containers running in a single Pod, it is possible to share volumes across those containers. In fact, tasks already do that for you. There are various ways to use this volume, or you could mount your own from an existing PersistentVolumeClaim.

Accessing the home directory

Deprecation notice

As documented in pull request #3878 (https://github.com/tektoncd/pipeline/pull/3878), this feature has been deprecated as of version 0.24. If you are using version 0.20.1 as specified in Chapter 3, Installation and Getting Started, it might work, but there are no guarantees that it won't break when using a more recent version of Tekton.

An easy way to share information across your steps is to use the home directory directly. When tasks are initiated, the task run will mount a volume named /tekton/home in each container that runs a step. Accessing this folder is simply a matter of changing the directory to ~.
