Unable to run tests inside docker with Intellij IDEA (works in RubyMine) which leads to "Uncaught exception: Unknown MySQL server host 'db'" #1

With Intellij IDEA 2017.3.2, I am unable to execute code inside docker for any run configuration. It always use my local ruby which is pointless.

Uncaught exception: Unknown MySQL server host 'db' (0)

Stacktraces are the same for both rails and idea

It looks like it's pointless to have docker and docker-compose remote integration if it can't run configurations in them. The only thing you get from setting it in Docker with Intellij is to get the IDE completions or I'm doing something wrong 👈

This is the execution when using the docker integration in RubyMine:

Array values in the parameter to `Gem.paths=` are deprecated.
Please use a String or nil.
An Array ({"GEM_PATH"=>["/usr/local/bundle", "/root/.gem/ruby/2.2.0", "/usr/local/lib/ruby/gems/2.2.0"]}) was passed in from /opt/project/bin/rspec:3:in `load'
Run options: include {:full_description=>/User\ \#email\ returns\ a\ string/}

For example above, /usr/local/bundle/gems/ruby-debug-ide-0.6.0/bin/rdebug-ide is actually inside docker.

I managed to find that module has it's own Ruby SDK and Gems section in Intellij idea too:

But I'm now getting

Run Configuration Error: Unable to find Rake executable script in SDK 'Remote: ruby-2.2.4-p230'

I managed to get passed this issue by deleting Gemfile.loc then doing bundle install. I am using rbenv, so I had to make sure that rbenv is pointing to the right Ruby version (2.5.1 in my case) AND the corresponding bundler is installed: gem install bundler.

I have had some tough days with IntelliJ Ruby plugin (I am using IntelliJ Ultimate), so check my StackOverflow answer here too
