[MM3-users] scheduled tasks in docker-based deployments

I came across the section http://docs.mailman3.org/en/latest/config-web.html#scheduled-tasks-required that claims that crontab entries are *required* for normal MM3 operations, but I do not see anything like that in docker-based implementation. Should I add similar cron jobs manually to the host box?
