Using xdebug through Docker container in PhpStorm

I've read some posts about this but none helped in my case or simply overlooked the missing piece.

I cannot get xdebug to work on PhpStorm using a Docker container.

Docker-compose.yml

version: '2'

services:
  web:
    image: nginx:latest
    volumes:
    - .:/usr/share/nginx/html
    - ./nginx/nginx.conf:/etc/nginx/nginx.conf
    - ./nginx/logs:/var/logs/nginx
    - ./nginx/site-enabled/default.conf:/etc/nginx/sites-enabled/default.conf
    ports:
    - "80:80"
    depends_on:
    - php

  db:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: 1234
      MYSQL_DATABASE: local_db
      MYSQL_USER: root
      MYSQL_PASSWORD: 1234
    ports:
    - "3306:3306"

  php:
    build: images/php
    volumes:
    - .:/usr/share/nginx/html
    - ./config/docker/php/php.ini:/usr/local/etc/php/php.ini
    - ./config/docker/php/ext-xdebug.ini:/usr/local/etc/php/conf.d/ext-xdebug.ini
    - ./config/docker/php/php-fpm.conf:/usr/local/etc/php-fpm.conf
    user: www-data
    depends_on:
    - db

config/docker/php/ext-xdebug.ini

zend_extension="/usr/lib/php7/xdebug.so"
xdebug.remote_enable=1
xdebug.remote_port=9000
xdebug.overload_var_dump=1
xdebug.default_enable=1
xdebug.remote_autostart=1
xdebug.idekey=PHPSTORM
xdebug.remote_connect_back=1
xdebug.remote_host=172.20.0.1 # ip of host inside docker container
xdebug.remote_log=/usr/share/nginx/html/xdebug.log

error from xdebug.log

In PhpStorm I'm using remote debugger with following settings:

server

Host - 127.0.0.1  
Port - 80

Absolute path on server

/usr/share/nginx/html

IDE session key

I've found that the following config on ext-xdebug.ini works for Docker for Mac

xdebug.remote_connect_back=0
xdebug.remote_host=host.docker.internal

Docker automatically defines host.docker.internal within containers. So we simply point xdebug to think host.docker.internal is the IP of host machine (which obviously is). This way, we don't have to rely on ever changing internal IP between docker container and host.

More information can be found here https://docs.docker.com/docker-for-mac/networking/#use-cases-and-workarounds

Ok I got the solution in here

https://forums.docker.com/t/ip-address-for-xdebug/10460/9

I had to set my internal ip to xdebug.remote_host and disable xdebug.remote_connect_back=0

Seems this is a osx thing. Hope this helps someone here
