how to debug gitlab-ce docker container?

My environment: osx14.0 rubymine gitlab-ce 16.4

I want to debug gitlab-ce remotelly with local rubymine on my mac. I expose 3000 in the docker container, but rubymine cannot debug it on 3000 port directly. I am more familiar to Java and PHP, but new to ruby thanks!

I tried to use rubymine connect to 3000 port on the docker container, but I failed
