GitHub Actions Docker permission denied error running mix

• Laravel Mix Version: 6.0.42 (npm list --depth=0)
• Node Version (node -v): v16.14.0
• NPM Version (npm -v): 8.3.1
• OS: Ubuntu 20.04 in Docker

Description:

When using Laravel Mix in GitHub Actions using a Docker image with PHP + Node inside, Laravel Mix gives a permission error:

Run npm run production

> production
> mix --production

npm install works fine and can write node_modules fine.

Steps To Reproduce:

I’ve setup a public repository that shows off the problem, here is the workflow run showing the same error message:

Sorry for my late reply. @trip-somers @thecrypticace @nklmilojevic

I’ve got a workaround working for this just by adding a step before npm run production:

    - name: Fix Laravel Mix permissions issue
      run: chmod -R 0777 public

This is a hack at best, so this still needs fixing in some way. Not sure if its a mix bug or a GitHub actions bug if I’m honest as this bug doesn’t occur when using a shared runner.

Have you ever solved this problem? I don’t think it’s a mix issue, it’s a docker issue… Existing projects are all fine, but new ones don’t work. Has the docker permission policy changed to be more detailed?
