Volume Ownership Changes by Mount Point

[brendan-stephens]

I'm confused why the ownership changes to (esp group 'nobody') when I change the mount point in the container.

Using a mac host --

id
uid=501(user.name) gid=20(staff)

podman machine init --timezone local --now --disk-size 60 --memory=8192 -v "${HOME}"

podman run fedora:38 id             
uid=1000(user.name) gid=1000(user.name) groups=1000(user.name)

podman run -v ~/Projects fedora:38 ls -ln /Users/user.name 
drwxr-xr-x. 2 1000 1000 6 Mar 27 19:09 Projects

podman run -v ~/Projects fedora:38 ls -l /Users/user.name 
drwxr-xr-x. 2 user.name user.name 6 Mar 27 19:09 Projects

If I mount under the user home directory, I can preserve the user but not the group?

podman run -v ~/Projects:/home/user.name/Projects fedora:38 ls -l /home/user.name
drwxr-xr-x. 5 root nobody 160 Mar 26 20:07 Projects

podman run --userns keep-id:uid=1000,gid=1000 -v ~/Projects:/home/user.name/Projects fedora:38 ls -l /home/user.name
drwxr-xr-x. 5 user.name nobody 160 Mar 26 20:07 Projects

Is it due to the mapping?

podman run --userns keep-id:uid=1000,gid=1000 fedora:38 cat /etc/subuid
user.name:524288:65536

podman run --userns keep-id:uid=1000,gid=1000 fedora:38 cat /etc/subgid
user.name:524288:65536
