managing reboot / update on micro OS when some container are running

Hi, I consider to set up a micro-OS mini server for some containers (homeassistant / influx db / graphana ...maybe thingsboard) My concerns is how to manage, a clean stop of the containers, let micro-OS update and then retarts the containers stack . was wondering on how to, - schedule the updates in predictable or defined time windows, to be able to stop my processes and trigger the update - or let them happen whenever a new release is available and find a way to secure my setup each time before it happens (is there an alert or trigger available to catch ? ) I didn't managed to find detailled info on those topics :/ Is there some sort of documentation (wiki /how's to) on those aspect somewhere?
