This looked so promising.

Via SSH, I can indeed use docker attach and from within I can issue a stop for MC server. Works fine.

However, the Synology task scheduler via DSM doesn’t seem to be able to similarly attach and then issue the stop command. I get this back via email (for when a scheduled task fails):

Task Scheduler has completed a scheduled task.

Task: MC Graceful Restart Start time: Tue, 29 Aug 2023 17:19:41 -0500 Stop time: Tue, 29 Aug 2023 17:19:42 -0500 Current status: 127 (Interrupted) Standard output/error:

the input device is not a TTY /bin/bash: line 1: stop: command not found

I wish the acronym CPM was defined. Maybe I overlooked it.
