Taking a long time for Docker container to stop

$ time docker stop py-kms
py-kms

Maybe the stop signal is incorrect or needs to be setup properly in the application code?

It never actually succeeds in stopping the container at all. It’s waiting 10 seconds for a graceful stop (which never happens) and then it’s sending the container the kill signal:

The main process inside the container will receive SIGTERM, and after a grace period, SIGKILL.

As also noted in the Docker documentation the default waiting period is 10 seconds (which is what I’m observing as the time it takes to stop the container):

Name, shorthand	Default	Description
--time , -t	10	Seconds to wait for stop before killing it

Seems fixed now:

$ time docker stop py-kms
py-kms
