How to restart / update ioBroker Container

[MartinSchlender]

Hi,
I used ioBroker for the past years (6 years I think) and switched over to a docker installation now (why the heck didn't I do it years ago :-))
One question I could not see answered is the use of maintenance mode. Let´s assume I would like to change my container config in any way (add a port etc.) and therefore would like to re-deploy it.
Should I first enter maintenance mode in order to stop iob cleanly?
With just deploying I'm always afraid to lose data (eg. states not yet written to my mariaDB etc.)
Thanks
Martin

The buanet/iobroker Docker image implements a proper graceful shutdown mechanism:

When Docker sends SIGTERM to the container, a trap handler catches it. The shutdown function uses pkill -u iobroker -f iobroker.js-controller to send SIGTERM to ioBroker processes, the system waits for processes to terminate naturally with a timeout period.
Only if processes don't terminate within the timeout, SIGKILL is used as a last resort.

This ensures that ioBroker has time to:

• Close database connections
• Save state information
• Release resources properly

You don't need to activate the maintenance mode.
