Problem detecting gems from a Docker Machine

Hi,

Recently I have started working with Docker as development environment for Rails applications. I am user the "Passenger + Ruby" image for my projects.

I wanted to configure RubyMine to work with this environment with no result.

When going to Preferences > Ruby SDK and Gems > + and add my machine:

1. Docker Compose
2. Server: Docker
   Configuration file(s): ./docker-compose.yml
   Service: <my current Rails service>
   Ruby interpreter path: /usr/local/rvm/rubies/ruby-2.5.1/bin/ruby

Nothing happens, no errors are displayed but neither gems are shown.

How can I solve that issue and index gems from my project in RubyMine?
