Using xdebug through Docker container in PhpStorm

问题:

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

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

回答2:

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
