使用 XDebug、VSCode 和 Docker 进行调试

Question

我正在尝试通过docker4drupal和 VSCode 在 Docker 中配置 XDebug，但我什么也没得到，尽管我遵循了这个：

• https://medium.com/@jasonterando/debugging-with-visual-studio-code-xdebug-and-docker-on-windows-b63a10b0dec

• https://github.com/felixfbecker/vscode-php-debug

• https://wodby.com/docs/stacks/drupal/local/#xdebug

这是我的 docker-compose.yml

我的 launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Listen for XDebug",
            "type": "php",
            "request": "launch",
            "port": 9000,
            "pathMappings": {

            },
            "xdebugSettings": {

                "max_depth": 5
            }
        }
    ]
}

我在.vscode/launch.json

我的结构也是：

/Users/oskar/Webapps/Docker/project/docker/

当我尝试运行调试时，我什么也没得到。

我知道这很旧但是因为我让它工作我想我会为其他人留下足迹。 这是我必须为 php-apache 容器放入 Dockerfile 的内容

# enable xdebug
RUN docker-php-ext-enable xdebug

# precreate log file for xdebug
RUN echo " " >> xdebug.log \
&& chown www-data:www-data xdebug.log \
&& chmod 774 xdebug.log \
# precreate directory for xdebug profiler
&& mkdir profiles \
&& chown www-data:www-data profiles \
&& chmod 774 profiles\
# precreate directory for xdebug tracer
&& mkdir traces \
&& chown www-data:www-data traces \
&& chmod 774 traces

# create and move xdebug.ini initialization file to start up dir
# Add Xdebug to PHP configuration
# See https://xdebug.org/docs/all_settings
RUN echo "" >> xdebug.ini \
&& echo "[xdebug]" >> xdebug.ini \
&& echo "zend_extension = /usr/local/lib/php/extensions/no-debug-non-zts-20180731/xdebug.so" >> xdebug.ini \
&& echo "xdebug.remote_enable = 1" >> xdebug.ini \
#profile setting
&& echo "xdebug.profiler_enable = 0" >> xdebug.ini \
#               use url param XDEBUG_PROFILE nothing or secret found in profile_enable_trigger_value
&& echo "xdebug.profiler_enable_trigger = 1" >> xdebug.ini \
&& echo "xdebug.profiler_output_name = readxdebug.out.%t.pro" >> xdebug.ini \
&& echo "xdebug.profiler_output_dir = /usr/local/etc/php/profiles" >> xdebug.ini \
#trace setting
&& echo "xdebug.trace_enable_trigger = 1" >> xdebug.ini \
#               use url param XDEBUG_TRACE nothing or secret found in trace_enable_trigger_value
&& echo "xdebug.trace_output_name = readtrace.%c" >> xdebug.ini \
&& echo "xdebug.trace_output_dir = /usr/local/etc/php/traces" >> xdebug.ini \
#
&& echo "xdebug.remote_autostart = 1" >> xdebug.ini \
&& echo "xdebug.remote_host = host.docker.internal" >> xdebug.ini\
&& echo "xdebug.default_enable=1" >> xdebug.ini\
&& echo "xdebug.remote_port=9000" >> xdebug.ini\
&& echo "xdebug.remote_connect_back=0" >> xdebug.ini\
&& echo "xdebug.idekey=VSCODE" >> xdebug.ini\
&& echo "xdebug.remote_log=/usr/local/etc/php/xdebug.log" >> xdebug.ini\
&& mv xdebug.ini /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini

我将 XDEBUG 配置为使用 url 参数 XDEBUG_PROFILE 触发配置文件，并使用 url 参数 XDEBUG_TRACE 进行跟踪。

我还使用以下命令将配置文件或跟踪输出文件移动到给定项目的映射目录

docker exec -t docker_myprojapp_1 bash -c "mv /usr/local/etc/php/profiles/*.xt /var/
www/html/projectname/dev/profiles/"

docker exec -t docker_myprojapp_1 bash -c "mv /usr/local/etc/php/traces/*.xt /var/
www/html/projectname/dev/traces/"
