Craig W commented on MESOS-809:
-------------------------------

First off, thanks for your work on mesos.

Can you add a note to the documentation to describe the purpose of LIBPROCESS_PORT, unless the public_ip / public_port become command-line args. I ran into a problem today that took me hours to solve by setting the LIBPROCESS_PORT environment variable.

> With tools like Docker making containers more manageable, it's tempting to use containers for all software installation. The CoreOS project is an example of this.
> When an application is run inside a container it sees a different ip/hostname from the host system running the container. That ip is only valid from inside that host, no other machine can see it.
> From inside a container, the Mesos master and slave publish that private ip to zookeeper and as a result they can't find each other if they're on different machines. The --ip option can't help because the public ip isn't available for binding from within a container.
> Essentially, from inside the container, mesos processes don't know the ip they're available at (they may not know the port either).
> It would be nice to bootstrap the processes with the correct ip for them to publish to zookeeper.
