Share artifacts between workflows / Github Actions

问题

I know that you can share artifacts between jobs of the same workflow...

But how can I share artifacts across different workflows?

回答1:

Probably not yet doable:

After a workflow ends, you can download an archive of the uploaded artifacts on GitHub by finding the workflow run in the Actions tab. GitHub does not currently offer a REST API to retrieve uploaded artifacts.

If you need to access artifacts from a previously run workflow, you'll need to store the artifacts somewhere. For example, you could run a script at the end of your workflow to store build artifacts on Amazon S3 or Artifactory, and then use the storage service's API to retrieve those artifacts in a future workflow.

GitHub has now added a REST API for downloading artifacts. Basically you do

GET repos/{owner}/{repo}/actions/artifacts/{artifact_id}/{archive_format}

And then you'll have to look for Location: in the response, and then access that url to download the artifact. The url is valid for 1 minute.

There's a GitHub Action that uses the API above that you can easily add to your workflow. I use it like this

- name: Download artifact
  uses: dawidd6/action-download-artifact@v2
  with:
    workflow: ${{ github.event.workflow_run.workflow_id }}
    workflow_conclusion: success
