Upload-artifact: Upload-artifact not working for steps running in containers

[zakkak]

Hello,

I have a yml using a container to run steps:

    runs-on: ubuntu-18.04
    container:
      image: my-container-on-docker-hub:latest
      volumes:
        - /github/home/.folder:/github/home/.folder
    steps:
    - name: ls
      run: ls -la $HOME
    - uses: actions/upload-artifact@master
      with:
        name: my-artifact
        path: /github/home/.folder

Inside the container if I ls -la /github/home I get:

total 16
drwxr-xr-x 4 1001  115 4096 Sep 12 23:47 .
drwxr-xr-x 4 root root 4096 Sep 12 23:47 ..
drwxr-xr-x 3 root root 4096 Sep 12 23:47 .folder
drwxr-xr-x 2 root root 4096 Sep 12 23:47 .ssh

However the upload-artifact step returns:

Run actions/upload-artifact@master
  with:
    name: my-artifact
    path: /github/home/.folder
##[error]Path does not exist /github/home/.folder
##[error]Exit code 1 returned from process: file name '/home/runner/runners/2.157.3/bin/Runner.PluginHost', arguments 'action "GitHub.Runner.Plugins.Artifact.PublishArtifact, Runner.Plugins"'.

I suspect that upload-artifact runs outside of the container and that's why I tried using volumes to make the data accessible on both sides, but it didn't help.
Is this an issue with volumes or upload-artifact?

Thanks

I'm afraid that I might be facing the same issue. Have you tackled that?

The upload-artifact runs on the host vm, not inside the container, so it can't access $HOME inside the container, please try put anything you want to load under $GITHUB_WORKSPACE, so the upload-artifact can access them.

@TingluoHuang so to my understanding the reason my config is not working is due to some issue in container.volumes since this is supposed to map (and sync I guess) the host folder with the container folder. Is that right?

@mballoni looking at https://github.com/mballoni/boot-validator/commit/cc2a9595750d01d99568ab816c55fa60272fc9e6 I think that your issue is #3, since i don't see any containers in your workflow.

@zakkak yes, map a host folder into container.

Uploading an artifact from a container should now work with the v2-preview

See: https://github.com/actions/upload-artifact/issues/62

v2 upload artifact has been released! https://github.blog/changelog/2020-04-28-github-actions-v2-artifact-actions/

Upload and download should now work properly in containers
