Bitbucket Blitz | Share artifacts between parent and child pipelines

[#1]

Welcome to the Bitbucket Blitz video series. The series features a library of short-form videos that, together, capture the end-to-end flow developers use to get sh&t done with our Software Collection. There is a specific focus on Bitbucket and Bitbucket Pipelines features.

A better developer experience is a few steps away.

As a follow-up to the previous post about splitting your bitbucket-pipelines.yml into multiple, smaller files and using shared pipeline syntax to tie them together, this video shows how you can share artifacts between parent and child pipelines.

Without artifact sharing, every child pipeline has to repeat expensive steps like downloading dependencies and building application code from scratch. That's wasted compute and wasted developer time that doesn't benefit your customers.

Bitbucket Pipelines now lets you specify an artifacts section on child pipelines, with upload and download keywords:

• Artifacts listed under upload are moved from the parent pipeline into the child pipeline where they can be used, and potentially modified.

• Artifacts listed under download are moved from the child pipeline back up to the calling parent pipeline where they can be used and potentially passed to other child pipelines.

A parent pipeline can download artifacts from a build child pipeline and then upload them to a testing child pipeline. Build once, share everywhere. No redundant steps.

In this Bitbucket Blitz video, I walk through how to set up artifact sharing between parent and child pipelines so you can keep your pipelines modular, fast, and easier to maintain across repositories.
