When using service in swarm, dockercloud/haproxy fails to link backend for services deployed globally.

 serviceA:
 deploy:
 mode: global

Workaround is to switch to replicated deploy mode (which is the default).

 serviceA:
 deploy:
 mode: replicated
 replicas: 3

It seems the containers created for globally deployed services are named differently, with a 0 as the second part of the name instead of the node id.

This should be fixed, and/or a warning should be added in the documentation if not.
