I have several Docker containers with one Moodle instance each. For the Docker configuration I use the following file:

zend_extension=xdebug.so
xdebug.mode=develop,debug
xdebug.start_with_request=yes
xdebug.discover_client_host=0
xdebug.client_host=host.docker.internal

And in docker-compose.yml:

 php:
    extra_hosts:
       - "host.docker.internal:host-gateway".
    build:
      context: .
      dockerfile: Dockerfile
    ports:
      - 80:80
    volumes:
      - ./src:/var/www/html/
      - ./moodledata:/var/www/moodledata

The problem is that it only works in one of the containers; specifically, the one I launch first. Can there be any conflict between both with this configuration? To listen I use PHPStorm.
