Anindya Sinha commented on MESOS-809:
-------------------------------------
I have a patch internally which adds public_ip and public_port to mesos command
line args (as optional params).
If set, these values are passed over to libprocess via 2 separate env vars
(similar to LIBPROCESS_IP and LIBPROCESS_PORT), say $PUBLIC_IP and
$PUBLIC_PORT. mesos would still bind the socket on
[$LIBPROCESS_IP:$LIBPROCESS_PORT] (as existing functionality), but for the rest
of the cluster (such as to advertise to zookeeper), it would use
$PUBLIC_IP:$PUBLIC_PORT, ie. to be specific, __ip__ and __port__ would be set
to $PUBLIC_IP and $PUBLIC_PORT in that case.
> External control of the ip that Mesos components publish to zookeeper

> Key: MESOS-809
> URL: https://issues.apache.org/jira/browse/MESOS-809
> Project: Mesos
> Issue Type: Improvement
> Components: framework, master, slave
> Affects Versions: 0.14.2
> Reporter: Khalid Goudeaux
> Priority: Minor
>
> 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.
