Profiling Apps running in Docker

I've followed the steps to set up RbSpy on my machine but when I go to run a configuration with profiling I get the following error:

bundler: command not found: /usr/local/bin/rbspy

The Docker Compose instance of my app is looking inside the container for the RbSpy path, which it won't find. Do I need to add it to the Docker image or is there a way to connect remotely for profiling?
