We can reuse init from phusion/baseimage to properly reap child processes.

@bobrik start the mesos_slave container with "--pid=host" so that it uses the process namespace of the host.

otherwise it seems that "docker wait" cannot be killed properly because it is running "inside" the Mesos Slave container.

(edit) Here is some information on the --pid flag: https://github.com/docker/docker/issues/8568

[bobrik]

That's should be noted in README, I suppose.

[ederst]

Yup. IMHO this should be mentioned in serveral docs:

• https://github.com/mesosphere/docker-containers/blob/master/mesos/README.md
• https://mesosphere.com/docs/tutorials/mesosphere-on-a-single-coreos-instance/

And also the service script of the CoreOS example should be updated:

• https://github.com/mesosphere/coreos-setup/blob/master/etc/systemd/system/mesos-slave.service

But I don't know if this is in any way supported by the Mesosphere guys. At least it would be possible to provide pull requests for the GitHub stuff.
