Original GitHub issue: https://github.com/nektos/act/issues/551

Act version

act version 0.2.20

Expected behaviour

Running $ act -j vetting should run the vetting section in .github/workflows/build.xml

Actual behaviour

The process runs stops with the following message:

[Build/Vetting        ] Extracting content to '/github/'
[Build/Vetting        ] Exec command '[bash --noprofile --norc -eo pipefail /github/workflow/1]'

This is on a Mac OS BigSur 11.2.2 with the default Sandboxing enabled.

I have attempted downgrading Docker Desktop (to 2.5.0.1 from 3.1 latest), Turning off gRPC Fuse and none of this gets me anywhere.

It seems, from what I can work out, that the BigSur MacOS has made root a Read Only file system so adding /github/workflow will fail. This leads to the mount failing as there is no mount point. This is my current theory but I have only limited experience with Docker, Github Actions and Mac computers.

Workflow and/or repository

workflow 
name: example workflow

on: [push]

jobs:
  vetting:
    name: Vetting
    runs-on: ubuntu-latest
    timeout-minutes: 5
    steps:
      - name: Checkout Repo
        uses: actions/checkout@v2
      - name: Project Validation
        run: docker run --rm -v $(pwd):/app ******/devtools:project-validator

Steps to reproduce

  1. Clone repo (private)
  2. Enter cloned repo directory
  3. Run act -j vetting

act output

This looks like a duplicate of #410.

@catthehacker I tried that workaround and it did not work for me.

As far as I can tell the /github/workspace mkdir command is hardcoded which means it will always fail if docker cannot access the read-only root on BugSur.

The problem is not with Mac, mounting directories to docker container running in docker container is currently not supported.

Thank you. I hadn't realised that was what was happening. Or not in this case.

Is that spelled out anywhere in the documentation?

I see there's a privileged mode which allows docker to run inside docker. Would it be possible to apply this to act when it runs?

You can but it will fail, because the docker command you are executing in workflow doesn't know that it's already in docker container.
It will try to map path from act docker container to your container but it should map path from host to your container.
Sam already explained it perfectly
