Thanks, Ryan.  That solution sounds perfect.

Subject: Re: Killing Docker containers

The docker stop command will attempt to kill the container if it doesn't stop in 10 seconds
by default. I think we should be using this with the -t flag to control the time between stop
and kill rather than just using kill.

I'll try to submit a patch.

Cheers,

ryan

Hi All,

I'm working on prototyping Mesos+Marathon for our services platform, using apps deployed as
Docker containers.  Our applications register themselves with our service discovery framework
on startup and un-register themselves when they shut down (assuming they shut down reasonably
gracefully).  What I'm finding is that when Mesos shuts down a docker container, it uses "docker
kill" as opposed to "docker stop".  I can see the reasoning behind this, but it causes a problem
in that the container doesn't get a chance to clean up after itself.

Is this something that might be addressed?  Perhaps by trying docker stop and then running
kill if it doesn't shut down after 30 seconds or something?

Thanks,
Scott
