Docker SWARM only partially supported

[gitcatpeter]

Only System Ports and Internal ports are displayed when connected to any host which is a part of Docker Swarm.
No external docker ports though.

I had to use docker.sock mapping:
- /var/run/docker.sock:/var/run/docker.sock:ro
and
network_mode: host
