No support for UDP?

[pauljamescleary]

I was trying to start up a Bind9 server (that exposes 53 on tcp and udp) and could not figure out how to make that happen.

It appears as though that may not be possible given the port mappings that you have, which are an Int -> Option[Int], which precludes using a string like 53/udp

I have been unable to get the same working with the docker spotify client. However, I did manage to get this working with the docker-java client.

Unsure of next steps. I could contribute the code I have back (it would break compatibility), but the issue still remains that I could not get the docker spotify client working.
