cool thanks all for the guidance ...
as mentioned and advised here... i didn't like the fact of having that port
exposed and or having to filter it in the firewall for every swarm node
.... ended up fixing it like this:
```
relabel_configs:
- source_labels: [__address__]
target_label: __address__
replacement: '${1}80'
```
shouldn't this be added to documentation as well instead of guiding
possible new users to exposing this ports?
Ill be more than glad than submitting a MR on the documentation for both
this and the other thread i've been at if you guys agree.
