Can I store Xdebug inside separate docker container?

I am new to Docker and docker-compose. I have met the point that it's better to put each process to separate containers. So I put stuff like Composer, npm, artisan, Redis, pma to separate containers.

Now I am trying to integrate Xdebug and use it in PhpStorm. Can't understand how to put it separately. And should I actually? And do I understand this paradigm right?

My docker-compose.xml:

version: '3'
