Hi all,
What is the best way to stop an application via systemd (in my case a java app) using a script that waits up to a max. 1 minute for the java application to close correctly when the reboot/halt/poweroff command is invoked ?
We had thought of a unit like this:
The application starts correctly and if I call the same script from cli with the "stop" parameter (sudo systemctl stop myservice.service), the Java application stops correctly.
When I use the reboot/halt/shutdown command, systemd does not wait for the Java application to properly close.
Raspberry restarts/shuts down immediately without waiting for the Java application to close properly.
the function that stops the java application and possibly closes it after a minute present in myscript.sh is the following:
I was wondering if you have any suggestions for me to solve my problem ?
Thank you.
