如何在Ubuntu 16.04上设置Docker + PhpStorm + xdebug

Question

My problem is that xdebug doesn't work when I start listening port. I think PhpStorm can't link with xdebug. I just get debugger panel variables are not available. It's looks like xdebug have not correct settings.

Software and versions used:

Ubuntu 16.04 LTS
Docker v 17.06
docker-compose 1.15

So I was trying many times setup xdebug + Docker + PhpStorm but cannot do it. I've read many tutorials but nothing haven't helped me.

My docker-compose.yml looks like this:

version: '3'
services:
    web:
        image: nginx:latest
        ports:
            - "80:80"
        restart: on-failure
        volumes:
            - "./etc/nginx/default.conf:/etc/nginx/conf.d/default.conf"
            - "./etc/ssl:/etc/ssl"
            - "./project:/var/www/html/project"
        depends_on:
            - php
            - db

    php:
        image: nanoninja/php-fpm
        restart: on-failure
        volumes:
            - "./etc/php/php.ini:/usr/local/etc/php/conf.d/php.ini"
            - "./project:/var/www/html/project"
    db:
        image: mysql
        container_name: ${MYSQL_HOST}
        restart: on-failure
        env_file:
            - ".env"
        environment:
            - MYSQL_DATABASE=${MYSQL_DATABASE}
            - MYSQL_ROOT_PASSWORD=${MYSQL_ROOT_PASSWORD}
            - MYSQL_USER=${MYSQL_USER}
            - MYSQL_PASSWORD=${MYSQL_PASSWORD}
        command: mysqld --sql-mode=NO_ENGINE_SUBSTITUTION
        ports:
            - "8988:3306"
        volumes:
            - "./data/db/mysql:/var/lib/mysql"

My xdebug.ini is:

xdebug.default_enable=0
xdebug.remote_enable=1
xdebug.remote_port=9000
xdebug.remote_autostart=0
xdebug.remote_connect_back=0
xdebug.idekey="PHPSTORM"
xdebug.profiler_enable=0
xdebug.remote_host=localhost

I found out solution how to run xdebug.

1) First of we need create a new static route that will based on your network device. For create new static route: run in terminal ifconfig

and found out the exists network device. In my situation name of device will be as

wlp4s0

2) Go ahead. Let's begin create the static route. In terminal run command like this:

> sudo ip addr add 10.254.254.254/24 brd + dev wlp4s0 label wlp4s0:1

3) Now if you run again ifconfig you'll see new static route:

4) Update

xdebug.ini

file add:

xdebug.remote_host=10.254.254.254

5) Update docker.compose.yml file: in php section add:

environment:
    PHP_IDE_CONFIG: "serverName=project-docker"
    PHP_XDEBUG_ENABLED: 1
    XDEBUG_CONFIG: remote_host=10.254.254.254

6) The last thing is update phpstorm settings.

Server settings: Remote debug config: 7) And profit xdebug is working:

Linux上的Docker允许Xdebug自动连接回主机系统，因此您只需设置xdebug.remote_connect_back=1并xdebug.ini的xdebug.remote_host xdebug.ini 。
