Debug PHP with Xdebug in Docker with VSCode on Mac - php

Question

I am running a Symfony application inside a Docker-Container.
I want to debug the code with VSCode on my mac. With Windows everything works fine.
The debugger is connecting to the container, but does not stop at the breakpoints.
This is my launch.json
{
"version": "0.1.0",
"configurations": [{
"name": "Listen for XDebug",
"type": "php",
"request": "launch",
"port": 9003,
"log": true,
"externalConsole": false,
"pathMappings": {
"/srv/app": "${workspaceFolder}",
"/srv/cssp/src/WorkingBundle": "${workspaceFolder}/src/WorkingBundle"
},
"ignore": [
"**/vendor/**/*.php"
]
},
]
In the php.ini I added
xdebug.mode=debug
xdebug.client_host=host.docker.internal
xdebug.start_with_request=trigger
My Dockerfile
FROM composer:latest AS composer
FROM php:7.2-apache-stretch
COPY --chown=33:33 . /srv/cssp
COPY .docker/vhost.conf /etc/apache2/sites-available/000-default.conf
COPY .docker/php.ini /usr/local/lib/
COPY .docker/php.ini /usr/local/lib/php
COPY .docker/php.ini /usr/local/etc/php
WORKDIR /srv/symfonyApp
ENV COMPOSER_ALLOW_SUPERUSER 1
COPY --from=composer /usr/bin/composer /usr/bin/composer
