XDebug在映射文件夹时无法使用WordPress容器

Question

我有一个WordPress在docker composer上运行，我希望能够调试它。

我使用这个存储库作为Wordpress Docker xDebug Boilerplate的基础，我已经更改了一些内容。

这是我的码头作文：

version: '3.9'
services:
db:
platform: linux/x86_64
image: mysql:8.0
container_name: db
command: --default-authentication-plugin=mysql_native_password
restart: always
ports:
- 3306:3306
environment:
MYSQL_USER: db_user
MYSQL_PASSWORD: db_password
MYSQL_DATABASE: db_name
MYSQL_ROOT_PASSWORD: root
volumes:
- db_data:/var/lib/mysql
wordpress:
depends_on:
- db
build: .
image: wordpress:latest
restart: always
ports:
- 8888:80
env_file: .env
environment:
WORDPRESS_DB_HOST: db
WORDPRESS_DB_NAME: db_name
WORDPRESS_DB_USER: db_user
WORDPRESS_DB_PASSWORD: db_password
PHP_EXTENSION_XDEBUG: wp_password
volumes:
- wp_data:/var/www/html
- ./wp-content/:/var/www/html/wp-content/
volumes:
db_data:
wp_data:

我的Dockerfile:

FROM wordpress:latest
RUN pecl install xdebug 
&& docker-php-ext-enable xdebug 
&& echo "xdebug.mode=debug" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini 
&& echo "xdebug.client_host = host.docker.internal" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini

我在一个名为wp-content的文件夹中有一些内容，我在项目的根目录下创建了这个文件夹：

• 文件夹plugins
  • index.php文件
• 文件夹themes
  • 文件夹default
    • index.php文件
    • style.css文件

我的问题是：映射文件夹wp-content时，调试器不工作。我已经检查了端口配置等

我使用的是VSCode，这是我的launch.json文件：

{
"version": "0.2.0",
"configurations": [
{
"name": "Listen for XDebug",
"type": "php",
"request": "launch",
"port": 9003,
"pathMappings": {
"/var/www/html": "${workspaceFolder}/cms"
},
"xdebugSettings": {
"max_data": 65535,
"show_hidden": 1,
"max_children": 100,
"max_depth": 5
}
}
]
}

但是，如果/var/www/html的内容完全映射到另一个文件夹(例如cms(，则它可以完美地工作。

# wordpress service
volumes:
- './cms:/var/www/html'

如何让调试器将wp内容复制到WordPress容器中？

在我的配置神奇地工作之前，我必须添加大量的配置：PECL安装后

# install xdebug
RUN echo "zend_extension=/usr/local/lib/php/extensions/no-debug-non-zts-20160303/xdebug.so" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN echo "error_reporting = E_ALL" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN echo "display_startup_errors = On" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN echo "display_errors = On" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN echo "xdebug.idekey="PHPSTORM"" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN echo "xdebug.remote_port=9000" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN echo "xdebug.remote_enable=1" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN echo "xdebug.remote_autostart=1" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN echo "xdebug.remote_host=docker.for.win.localhost" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN echo 'xdebug.mode=debug' > /usr/local/etc/php/php.ini
RUN echo 'xdebug.client_host=host.docker.internal' > /usr/local/etc/php/php.ini
RUN echo 'xdebug.remote_autostart=0' > /usr/local/etc/php/php.ini
RUN echo 'xdebug.remote_enable=1' > /usr/local/etc/php/php.ini
RUN echo 'xdebug.default_enable=0' > /usr/local/etc/php/php.ini
RUN echo 'xdebug.remote_host=host.docker.internal' > /usr/local/etc/php/php.ini
RUN echo 'xdebug.remote_port=' > /usr/local/etc/php/php.ini
RUN echo 'xdebug.remote_connect_back=0' > /usr/local/etc/php/php.ini
RUN echo 'xdebug.profiler_enable=0' > /usr/local/etc/php/php.ini
RUN echo 'xdebug.remote_log="/tmp/xdebug.log"' > /usr/local/etc/php/php.ini
RUN echo 'xdebug.profiler_output_dir="/var/www/html/profiler"' > /usr/local/etc/php/php.ini
RUN echo 'xdebug.profiler_output_name="cachegrind.out.%p"' > /usr/local/etc/php/php.ini
RUN echo 'xdebug.cli_color=1' > /usr/local/etc/php/php.ini
RUN echo 'xdebug.profiler_append=1' > /usr/local/etc/php/php.ini

问题是我在launch.json文件中有错误的配置。我的pathMapping已设置为侦听cms文件夹。

我只需要从$worspaceFolder}/cms换成$worspaceFolder}/wp-content。

这是正确的launch.json:

{
"version": "0.2.0",
"configurations": [
{
"name": "Listen for XDebug",
"type": "php",
"request": "launch",
"port": 9003,
"pathMappings": {
"/var/www/html/wp-content": "${workspaceFolder}/wp-content"
},
"xdebugSettings": {
"max_data": 65535,
"show_hidden": 1,
"max_children": 100,
"max_depth": 5
}
}
]
}
