I encountered the following odd issue this week and took steps to reproduce.

I am running:

• macOS Monterey 12.4
• Docker Desktop 4.9.0 (80466)
• Docker Engine: 20.10.16

I've been told the bug is not reproducible on Linux, thus it likely only impacts Docker on Mac.

I have also verified that the problem does not exist if the "Enable VirtioFS accelerated directory sharing" experimental feature is enabled. However, the problem does exist regardless of the "Use the new Virtualization framework" experimental feature being enabled or not (assuming VirtioFS is not enabled).

git clone https://github.com/bboe/dockergit.git
cd dockergit
./run.sh

At this point you will have a shell in the container. Run git status and you might see the following:

/a $ git status
fatal: unsafe repository ('/a' is owned by someone else)
To add an exception for this directory, call:

    git config --global --add safe.directory /a

Here's where it becomes interesting. Simply run ls and then re-run git status and it should work as expected:

a/ $ ls
Dockerfile     README.md      run.sh
/a $ git status
On branch main
Your branch is up to date with 'origin/main'.

nothing to commit, working tree clean
