Ubuntu 22.04 - Rootless docker-compose sabnzbd writes as incorrect UID

I’m running into a frustrating problem. I’ve got a fresh Ubuntu 22.04 setup with Docker, docker-rootless and docker-compose. I’m trying to get sabnzbd and the *arrs working, but I’m a bit confused. I have PUID/PGID set to 1000 in the environment blocks of each of the containers. When I enter into bash of the abc user, I notice the UID is 1000 and GID is 1001. When I touch /shareVolume/testFromContainer.txt, that file shows as ownership/UID-GID of 100999. Thusly, other containers can’t read the files it writes. Also, Radarr can’t read my movies folder because of the permissions issues.

I should note that the folders in question are (movies) NFS shares and an SSD added via KVM, mounted via fstab. I feel like I’ve tried everything, but I don’t know what I’m looking for at this point. Any help would be appreciated.

We don’t support rootless docker. PUID/PGID is our version of dropping privileges for the app. The container needs to run as root.
