Getting artifact upload public URL in steps after upload

[AaronMT]

Hello,

In a GitHub Actions job, after google-github-actions/upload-cloud-storage@main step, I would like to get the public URL of the uploaded artifact from the previous step.

The idea is a job using the following steps as an example:

• Build a binary
• Upload binary as an artifact
• Fire off a Slack message with a public URL of said binary

How would you get the public URL of the artifact in a subsequent step?

- uses: google-github-actions/upload-cloud-storage@main
   name: Upload Artifact (json) to Google Cloud Storage
   with: 
       path: file
       destination:  bucket/output
       env-pub: FOOBAR
  -name: Use URL for something
    run: echo "${{ env.FOOBAR }}"

The last command would give me a public URL to the uploaded artifact.

That should do the trick:

steps:
  - id: upload-file
    name: Upload Artifact (json) to Google Cloud Storage
    uses: google-github-actions/upload-cloud-storage@main
    with:
      path: file
      destination:  bucket/output

  - name: Get public URL
    run: echo "PUBLIC_URL=https://storage.googleapis.com/${{ steps.upload-file.outputs.uploaded }}" | sed 's|gs://||' >> $GITHUB_ENV

  - name: Use URL for something
    run: echo "${{ env.PUBLIC_URL }}"

Hi @AaronMT does the workaround provided by @jakub-bacic (thanks!) work for you or were you looking for something else like a signed url?

I haven't had a chance to try it yet, but that looks like what I was looking for albeit as a workaround.

Was also looking for something like this.
The workaround works for me, apart from some minor details, particularly because I'm uploading a single file - otherwise it would involve iterating through the CSV list of files returned by ${{ steps.upload-file.outputs.uploaded }}.
Also, might be worth noting that the pipe to sed 's|gs://||' doesn't seem to be relevant anymore as the prefix and bucket are no longer returned. Since the bucket is not returned, that needs to be added when creating either the download link or the GS URI.

I am trying to achieve something similar, by copying artefacts from inside a docker container to the actual github runner on which the container run, and then try to upload these artefacts to google cloud. However, this works only if all tests in my suite pass, but if I have a failures then it gives the following error: google-github-actions/upload-cloud-storage failed with: ENOENT: no such file or directory, lstat '<path/to/test/report>'
