Subject Re: Populate DiscoveryInfo in Mesos

That sounds like a good idea! Great.

If you go ahead with this, please be so kind and start by posting a short design document
here on mailinglist (similar to those here https://github.com/apache/aurora/blob/master/docs/design-documents.md,
but probably shorter). 

This will allow us to split the discussion of the design from discussing the actual implementation.
I believe this is necessary, as the DiscoveryInfo protocol is quite flexible (http://mesos.apache.org/documentation/latest/app-framework-development-guide/).

Thanks,
Stephan

Subject: Populate DiscoveryInfo in Mesos

Hi,

It seems like Aurora does not populate the "discovery" field in either
TaskInfo or ExecutorInfo in mesos.proto
<https://github.com/apache/mesos/blob/master/include/mesos/mesos.proto#L438>
.

I'm considering adding this to support retrieving port map in Mesos
directly. This would enable us to discovery this information directly from
Mesos side, and also enables us to build one universal service discovery
solution for multiple frameworks including Aurora.

If no objection, I'll create a JIRA ticket for this task.

Thanks.
