I need to schedule systemd timers or fleet timers?

I’m building a reporting system that is essentially a small scratch container with a go static executable. The report runs every day at 12:00. I have a few other reports that run on different schedules. Currently I use fleet to schedule my reports but it get’s overly complicated trying to solve different monitoring, scheduling, configuration, and deployment. Fleet is still a good solution although I still need to solve some configuration management as I migrate to containers.

So the questions [a] how does rancher handle transient containers for all aspects of monitoring, scheduling, configuration, and deployment? [b] what sort of cron-like scheduling is available?

Rancher currently has no cron-like scheduling.
