Access external IP address from service

Is it possible to get the external IP address for a POD? It doesn't appear to be populating in the environmental variables for a service, so I was wondering if there was another way to get that information.

Basically: I'm setting up a proftpd service, and it needs to send out its external ip as well as a port for passive communication. Right now, it's sending the local IP address which is causing FTP clients to fail.

The kubernetes service discovery mechanism (DNS or environment variable) doesn't populate the external IP.

One way to work around is to create a static IP first, then assign it to your service.

Or you can exec kubectl inside your cluster to get the external IP but that's nasty.
