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 ~.
