@medyagh - question: on Linux, should we expose the true Docker IP & port, or is it better to always use 127.0.0.1 for consistency?

@medyagh - question: on Linux, should we expose the true Docker IP & port, or is it better to always use 127.0.0.1 for consistency?

For sure it is better to use the real ip.
So at least on linux we have a true service port experience.
@josedonizetti told me about a POC that we could implement real ip for Mac in the future.

So I would consider macOs networking a limitation that we will eventually make it as nice as Linux.

Merging and following up with a second PR to address shortcomings.
