Docker compose mounted volumes empty about cloud-builders-community HOT 5 OPEN

bump - also ran into this bug

from cloud-builders-community.

I've also been running into this issue lately and couldn't track down the cause. It works fine running in the Cloud, but local doesn't seem to mount volumes correctly. Usually it's empty, but one of my services has a few of the sub-folders visible. However, those sub-folders are also empty. I've tried relative and absolute paths.

I've also tried defining volumes separately (after the steps: section). Doing it this way creates a file-not-found error at least:

volumes:
  data:
    driver_opts:
      type: none
      device: /path-to-data
      o: bind

Is there a work-around for this issue?

@Philmod sorry to ping, but wondering if you have thoughts on this?

Maybe you have an idea of root cause?

I've ran into this issue as well, except with images based on 'gcr.io/cloud-builders/docker'. I was able to get mounted volumes to show up in 'gcr.io/cloud-builders/gsutil' layers, but only if I first include a step that calls docker run, explicitly mounting the volumes like this:

  - name: 'gcr.io/cloud-builders/docker'
    args: [ "run", "--rm", "-v", "vol1:/output", "gcr.io/$PROJECT_ID/tdc:latest"]
    volumes:
      - name: 'vol1'
        path: '/output'

Then the following step will correctly list the expected contents of /output:

  - name: 'gcr.io/cloud-builders/gsutil'
    entrypoint: "bash"
    args: [ "-c", "ls", "-l", "/workspace" ]
    volumes:
      - name: 'vol1'
        path: '/output'

However, the mounted volume /workspace is empty in the image 'cloud-builders-community/firebase', for example if I include a step like this:

  - name: 'gcr.io/$PROJECT_ID/firebase'
    entrypoint: 'bash'
    args: ['-c', 'ls', '-l', '/output', '.']
    volumes:
      - name: 'vol1'
        path: '/output'

I'm not sure if there's something I'm doing wrong or if it's a bug. Any help would be appreciated.
