Rootless podman cannot bind ports <1024, only root can by default (on pretty much any distro I guess). Have you done something like sysctl net.ipv4.ip_unprivileged_port_start=80 to allow non-root processes to bind to port numbers >=80?

That’s what I thought, but last time I looked I only saw a “release” tag, no “v2” tag. Did I miss something?

That server is also a homeserver I manage for family (in another city). The two homeservers then mutually back up each other.

They show images from the same day in past years. So if your library has no images >= 1 year old I’m not sure if anything shows up.

The same way as all other services: all relevant data (compose.yml and all volume mounts) are in a btrfs subvolume. Every night a snapshot gets made and mirrored to a remote server by btrbk.
