BIND MOUNT results in permission issue

[rycore]

I can't find any information on this, so I'm not sure if it's by design (not sure why it would be...), a docker issue in general or just UNRAID related, but when I try to mount the /var/www/html path to my appdata, allowing for easier access to the plugin folders, I get permission issues:

ln: ./adminer.css: Permission denied

And if I were to just specify the plugins-enabled folder

/usr/local/bin/entrypoint.sh: line 14: can't create plugins-enabled/001-highlight-monaco.php: Permission denied

I've tried correcting this with PGID, PUID as well as USER_ID and GROUP_ID and even adjust UMASK, but I was unsuccessful, all folder permissions appear fine, so I'm not sure what the issue would be.
