Swarm mode services cannot publish ports as both TCP and UDP

[jefflill]

Description

Docker swarm mode services cannot publish a port using both the TCP and UDP protocols.

Steps to reproduce the issue:

1. Create a swarm mode cluster.
2. Run: docker service create --name test -p 10000:10000 -p 10000:10000/udp alpine sleep 100000

Describe the results you received:
Error response from daemon: rpc error: code = 3 desc = EndpointSpec: duplicate published ports provided

Describe the results you expected:
The service should have been created with port 10000 mapped for both TCP and UDP.

Additional information you deem important (e.g. issue happens only occasionally):

I think this has just been fixed in moby/swarmkit#1632

[jefflill]

Thanks: Very cool!

I'll have to figure out how to get the latest unstable bits and try it out. Do you happen to know whether I can find these at http://test.docker.com or will I need to build this myself?

[aboch]

@jefflill Sorry I wasn't clear. The fix was just pushed to the swarmkit branch, but was not ported to docker/docker yet. When this is done via a vendoring PR, this issue can be closed.
So current docker build, does not have the fix yet.

[jefflill]

OK. Thanks.

i'll reopen as it's not fixed in docker/docker yet
