Comment 2 for bug 2048130

For containers running cron this seems plausible, cron doesn't expect to be stopped. Maybe we should consider replacing those with something based on systemd timers?

For the openstack containers I cannot reproduce the issue, e.g. kolla-designate_producer-container.service stops just cleanly for me. Can you check the log in /var/log/kolla for the affected service whether it shows some issue during shutdown?
