Share CI Data Across Steps and Stages

Updated 1 month ago by Doug Bothwell

This topic describes how to share CI data across Steps and Stages.

Share Data Across Steps

Each Stage has a common /harness folder. Any Step in the Stage can create, retrieve, update, and delete files in this folder.

You can declare Shared Paths for a Stage. Any Step in the Stage can create, retrieve, update, and delete data in a Shared Path. Suppose you use Maven to manage your software projects. Each Step uses /root/.m2 as the Maven repository, which is outside the common /harness folder. This means you need to declare it as a Shared Path in the Pipeline Editor.

To declare a Shared Path, open the Stage, go to the Overview tab, click Shared Paths, and add the subfolder such as /root/.m2. Once you do this, any Step can then access /root/.m2.

Share Data Across Stages

You can share data across Stages using AWS or GCS buckets:

  1. Save your cache using Save Cache to S3 or Save Cache to GCS.
  2. Retrieve your cache using Restore Cache from S3 or Restore Cache from GCS.
You cannot share access credentials or other Text Secrets across Stages.
