Docker API (socket) wrapper to get ports inside of a container. Plus serf -tags to expose mapped 49XXX ports.
It is intended to be used with Serf (not needed for Consul).
A common use case is to make your dockerized services ports available for a Serf cluster. This script will format -tags field so you'll be able to fetch port information from other cluster members.
I hope when libswarm becomes stable enough and some issues preventing Consul from working correctly (like flapping state due to tcp/udp binding in the wrong way, as well as problem with advertising the Consul client ports).
