docker module wont link port (but shell will)

Hi,

im running this[1] playbook against a server in order to start a logstash container, but i cannot get it to link the required ports.
This[2] is the full log of that run and nothing seems to be wrong, but when i do a docker ps i cannot see the ports[3].

If i run the corresponding docker command via the shell module[4], everything is fine as well and the ports are showing up just fine in the list[5]
This is a bit strange because the kibana[6] task runs all right and the port link is created.

Im not sure if this is a bug or not since this is my first attempt to run docker from ansible.

Cheers,
Mike
