Run Docker container as current user

[Kurt-von-Laven]

Fixes #1975.

Previously, mega-linter-runner ran the MegaLinter Docker image as root. Users whose files became owned by root as a consequence of this behavior will need to chown them to be owned by the appropriate user. This change only affects POSIX platforms, because process.getuid and process.getgid are only available there.

Proposed Changes

1. Instruct the MegaLinter Docker container to inherit the UID and GID of the mega-linter-runner process.

.... but CI seems to disagree ^^

[Kurt-von-Laven]

What sources of persistence between jobs are there (e.g., caching, artifacts, the Docker images themselves)? My instinct is that some files may still be owned by root that should never have been because of the bug this change seeks to fix.

Would love to see this merged as there seems to be no way to run megalinter without it trashing the current file permissions.

[Kurt-von-Laven]

I was never able to figure out why the tests where failing, but would love to get this wrapped up if anybody understands what is going on. We use rootless-docker both for improved security and to avoid modifying file ownership.

Any news on this?

[nvuillam]

If @Kurt-von-Laven (or any motivated contributor like you ?) finds some available time, it could move again :)

On my side, my docker level is not advanced enough to handle the task :/
