ruby_remote_debug_test

Repository for reproduction of ruby remote debug issue in IntelliJ IDEA Ultimate and RubyMine

Environment

• The official docker image is used (ruby:2.1.9), extended for ssh access in an own docker image
• RubyMine Version: 2016.3.2
• IntelliJ IDEA Ultimate: 2016.3.5

Project setup

• Find the example ruby files with example dependencies under src, the Gemfile contains two gems
• The source is copied to /var/www within the docker container as part of the docker image build. See https://github.com/KarolBuchta/ruby_remote_debug_test/blob/master/Dockerfile#L15
• bundle install is executed as part of the image build as well
• You can connect to the running docker container by typing

  docker exec -it rubytest bash

• See steps below for a detailed reproduction case

Reproduction of issue

1.) Install docker compose and docker for the operating system of choice

2.) Clone this repository

3.) Run this command from within the project root folder:

docker-compose up

4.) Open up the SDK Manager in IntelliJ IDEA Ultimate (Right Click Module -> Open Module settings) or in RubyMine via Preferences

5.) Add new Ruby SDK => Choose remote => Choose SSH credentials

6.) Use following settings:

  Host: localhost
  Port: 2222
  User: root
  AuthType: Password
  Password: root
  Ruby Path: /usr/local/bin/ruby

7.) Observe no Gems are found or copied to the local stubs folders, gems are not found by the IDE. The debugging previously used does also not work.

Further infos

• The same issue can be observed in both RubyMine as well as Ultimate.
• We have tried this with .rbenv on our live docker container as well, it was with jruby. Gems where neither found nor copied as well.
• This is the minimum config, with the official ruby docker image, still no success with discovering gems.

Role of this feature

• This setting is becoming more and more popular as many people are using docker as well
• This setting is critical for us as we use it to debug a central service in our application stack
