Question: How to use ruby-debug-ide with unicorn? How to use --attach-mode?

[isaiahshiner]

I'm running rails through unicorn, and it's not clear how to start the debugger when pointing to unicorn instead of rails. I assume --attach-mode can be used for this exact purpose, to start the rails and then attach to it later, but I can't find any information on how to do that, or really any user-focused documentation.

In some ways, this question is really just "where is the documentation?" After a lot of research, I am quite sure what I want to do is possible. RubyMine seems to do it automatically, it's just that VSCode users aren't typically trying to do this.

The relevant StackOverFlow question.

I am able to start using the very simple rdebug-ide -- ./bin/rails s, and then attach in VScode. It just isn't running my actual project.
