Capturing podman exec output

[ta-vroom]

I have a backup script that I wrote for a container. Normally, when I run this interactively via podman exec -it $container back-me-up.sh I get some output in the terminal. However when I move this command to a systemd unit, the journal is empty. I know I could maybe output this to a log shared with the host and tail that file in systemd, but that seems like too much work.

Am I missing something?

systemd captures stdout/err by default normally so I would expect this output to end up in the journal.
Are you sure you command logs anything, i.e. compare missing -it argument? Othwerwise journald might not allow a normal user to read logs under some circumstances, #26910

I think it's just not showing up because I am using systemctl --user --machine=... and journalctl as root and not as the user. I tried switching to the user in question and running things there, but it shows me $DBUS_SESSION_BUS_ADDRESS and $XDG_RUNTIME_DIR not defined.

When I tried running a command through a systemd service on another machine as my primary user (and not trying to isolate processes to service users) systemd and the journal captured the output as expected, so I am marking this as solved.
