crontab like snaps or interfaces

[Zhang Enwei]

I didn't find any snaps or interfaces that could support crontab or systemd.timer or that kind of timed operations.
The user story is: Suppose my snap uses syslog to save all the logs, how should logrotate work?
My simple understanding is that, my snap can set up some configurations that could be used by other snap for example let me name it as logrotate snap.

Thanks a lot.

Hello

Snapd now supports systemd timer units. While you won't be able to just rotate the logs stored in /var/log, you may be able to use this facility to rotate your own logs stored in $SNAP_DATA. The relevant documentation is here: https://snapcraft.io/docs/services-and-daemons (look for "timer"). If you have any questions about using that feature please ask on the snapcraft forum page associated with the documentation https://forum.snapcraft.io/t/services-and-daemons/12601
