Why don't breakpoints work in xdebug + phpstorm + docker?

Question

PHP

Good day to all! Trying to set up xdebug in phpstorm using docker.
I have nginx on which there are several virtual hosts, below is the docker-compose.yml code, snippet php-fpm Dockerfile and xdebug.ini

version: '3.1'
    
    volumes:
      esdata01:

    xdebug.var_display_max_depth=-1

I set it up according to the instructions, everything seemed to be fine, the validation passed, but when I set breakpoints and start listening, nothing happens. By the way, I also insisted through laradock - everything worked.
I suspect that this may be due to the fact that in the root directory /var/www in the php-fpm configuration there are several more directories with projects, perhaps a finer setting is needed.
Please help, thanks!

Answer 1

xdebug.idekey = "PHPSTORM"
xdebug.default_enable = 1
xdebug.remote_enable = 1
xdebug.remote_host = host.docker.internal

here with the latter it just starts up

+ I also have the Xdebug helper extension installed in chrome for convenience (for on/off)
