Running Nightwatch and selenium in dockers

[Michał Dulemba]

I'm trying to run test environment where each component is in a docker (nightwatchjs, browsers, selenium server).

But now i'm stuck in finding right "setup". I get "Connection is refused is Selenium started" all the time. 

And it is weird because i set up webdriverio in similar way and it works (repo forked from hulilabs repo).

Anybody can help ?
