php - Docker容器上的PHP XDebug在VS Code中不起作用(Laravel和docker-compose)

Question

我无法使用Visual Studio代码和Xdebug在docker-compose容器环境中运行php调试器。

我尝试了article中的所有步骤以及this或this和this等各种问题

我有这个docker-compose.yml文件(php容器部分):

version: '2'
services:
    php:
        build: 
            context: images/php
        ports: 
            - "9000:9000"
        volumes:
            - ./www:/var/www
        links:
            - mysql
        depends_on: 
            - mysql
        network_mode: "bridge"

./www卷是我的Laravel根应用程序路径，安装在php容器中:



这是我安装Xdebug的php Dockerfile部分:

RUN yes | pecl install xdebug \
    && echo "zend_extension=$(find /usr/local/lib/php/extensions/ -name xdebug.so)" > /usr/local/etc/php/conf.d/xdebug.ini \
    && echo 'xdebug.default_enable=1' >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo 'xdebug.remote_enable=1' >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo 'xdebug.remote_connect_back=1' >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo 'xdebug.remote_autostart=1' >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo 'xdebug.remote_handler="dbgp"' >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo 'xdebug.remote_port=9000' >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo 'xdebug.remote_host=0.0.0.0' >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo 'xdebug.max_nesting_level=250' >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo 'xdebug.remote_log=/var/www/xdebug.log' >> /usr/local/etc/php/conf.d/xdebug.ini \

当我构建容器时，我没有任何错误，并且将 shell 附加到php容器并运行php -v，我得到以下输出:

PHP 7.2.3 (cli) (built: Mar 22 2018 22:03:09) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies
    with Xdebug v2.6.1, Copyright (c) 2002-2018, by Derick Rethans

因此，Xdebug已安装到容器中。我安装了PHP调试扩展，并设置了VSCode调试配置:

{
    "version": "0.2.0",
    "configurations": [{
        "name": "Listen for XDebug on Docker",
        "type": "php",
        "request": "launch",
        "port": 9000,
        "pathMappings": {
            "/var/www": "${workspaceFolder}/www",
        },
        "log": true,
        "ignore": [
            "**/vendor/**/*.php"
        ]
    }]
}

该应用程序正在运行，我在此行将断点设置为www/public/index.php

$app = require_once __DIR__.'/../bootstrap/app.php';

并开始调试。我有一个调试控制台输出:

<- launchResponse
Response {
  seq: 0,
  type: 'response',
  request_seq: 2,
  command: 'launch',
  success: true }

当我在浏览器中刷新应用程序时，我的laravel根目录中有两个新日志进入./www/xdebug.log文件:

但是调试器不会停止到我的断点。我尝试多次更改xdebug参数和vscode配置，但无法解决问题。

请帮助我，我的想法已经用完了...

只是自己弄清楚了，以为我会发布它，以防其他人解决问题

据我了解，remote_host应该设置为'host.docker.internal'

我已经在我的docker-compose文件中设置了它:

version: '3'
services:
  phpapp:
    image: phpapp
    container_name: phpapp
    environment: 
      XDEBUG_CONFIG: remote_host=host.docker.internal remote_port=9050 remote_enable=1 remote_autostart=1
    ports:
      - '8080:80'
    volumes:
      - 'c:/dev/www:/var/www/html'
