Enable/Disable xDebug through Docker-Compose, is it possible?

问题

我有以下的Dockerfile：

  1. FROM php:7.2-apache
  2. RUN apt-get update && apt-get install -y \
  3.         zlib1g-dev \
  4.         git \
  5.         unzip \
  6.     && rm -rf /var/lib/apt/lists/ \
  7.     && docker-php-ext-install zip pdo_mysql bcmath \
  8.     && a2enmod rewrite \
  9.     && pecl install xdebug-2.9.0 redis \
  10.     && docker-php-ext-enable xdebug redis \
  11.     && mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini" \
  12.     && mv /var/www/html /var/www \
  13.     && chown -R www-data:www-data /var/www/ \
  14.     && ln -s /usr/local/bin/php /usr/bin/php
  15. COPY --from=composer:1.9 /usr/bin/composer /usr/bin/composer
  16. WORKDIR /var/www/drm-case
  17. CMD ["docker/apache/bootstrap.sh"]

这是使用前面的Dockerfile构建容器的docker-compose.yml文件（不是每次都用）：

  1. version: "2.4"
  3. services:
  4.   case-v2-apache:
  5.     container_name: local-dev
  6.     image: local-dev:1.6 # 当更改Dockerfile时，增加此数字
  7.     depends_on:
  8.       mysql-server:
  9.         condition: service_healthy
  10.     volumes:
  11.       - ${LOCAL_PATH}:/var/www:delegated
  12.       - ${LOCAL_PATH}/docker/apache/conf.d:/usr/local/etc/php/conf.d
  13.       - ${LOCAL_PATH}/docker/apache/conf-enabled/servername.conf:/etc/apache2/conf-enabled/servername.conf
  14.       - ${LOCAL_PATH}/docker/apache/sites-available/000-default.conf:/etc/apache2/sites-available/000-default.conf
  15.     ports:
  16.       - "8009:80"
  17.     logging:
  18.       driver: "json-file"
  19.       options:
  20.         max-size: "10m"
  21.         max-file: "3"
  22.     build:
  23.       context: ${LOCAL_PATH:-./local-dev}
  24.       dockerfile: docker/apache/Dockerfile
  25.     networks:
  26.       - main
  27.     environment:
  28.       - VIRTUAL_HOST=local-dev.localhost
  29.       - COMPOSER_MEMORY_LIMIT=-1
  30.       - COMPOSER_AUTH=${COMPOSER_AUTH}
  31.       - COMPOSER_ALLOW_SUPERUSER=1
  32.       - PHP_IDE_CONFIG=serverName=local-dev

在这一行中被复制的文件${LOCAL_PATH}/docker/apache/conf.d:/usr/local/etc/php/conf.d与xdebug相关，意味着它是启用和设置扩展的文件。

想知道是否有一种通过使用ARG或ENV变量来告诉Docker在启动容器时启用/禁用xDebug的方法？有人以前尝试过这样的事情吗？如果有的话，你能帮我提供一些想法吗？

英文:

I have the following Dockerfile:

  1. FROM php:7.2-apache
  2. RUN apt-get update && apt-get install -y \
  3.         zlib1g-dev \
  4.         git \
  5.         unzip \
  6.     && rm -rf /var/lib/apt/lists/ \
  7.     && docker-php-ext-install zip pdo_mysql bcmath \
  8.     && a2enmod rewrite \
  9.     && pecl install xdebug-2.9.0 redis \
  10.     && docker-php-ext-enable xdebug redis \
  11.     && mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini" \
  12.     && mv /var/www/html /var/www \
  13.     && chown -R www-data:www-data /var/www/ \
  14.     && ln -s /usr/local/bin/php /usr/bin/php
  15. COPY --from=composer:1.9 /usr/bin/composer /usr/bin/composer
  16. WORKDIR /var/www/drm-case
  17. CMD ["docker/apache/bootstrap.sh"]

And this is the docker-compose.yml file that uses the previous Dockerfile to build the containers (not all the time though):

  1. version: "2.4"
  3. services:
  4.   case-v2-apache:
  5.     container_name: local-dev
  6.     image: local-dev:1.6 # increase this number when changing the Dockerfile
  7.     depends_on:
  8.       mysql-server:
  9.         condition: service_healthy
  10.     volumes:
  11.       - ${LOCAL_PATH}:/var/www:delegated
  12.       - ${LOCAL_PATH}/docker/apache/conf.d:/usr/local/etc/php/conf.d
  13.       - ${LOCAL_PATH}/docker/apache/conf-enabled/servername.conf:/etc/apache2/conf-enabled/servername.conf
  14.       - ${LOCAL_PATH}/docker/apache/sites-available/000-default.conf:/etc/apache2/sites-available/000-default.conf
  15.     ports:
  16.       - "8009:80"
  17.     logging:
  18.       driver: "json-file"
  19.       options:
  20.         max-size: "10m"
  21.         max-file: "3"
  22.     build:
  23.       context: ${LOCAL_PATH:-./local-dev}
  24.       dockerfile: docker/apache/Dockerfile
  25.     networks:
  26.       - main
  27.     environment:
  28.       - VIRTUAL_HOST=local-dev.localhost
  29.       - COMPOSER_MEMORY_LIMIT=-1
  30.       - COMPOSER_AUTH=${COMPOSER_AUTH}
  31.       - COMPOSER_ALLOW_SUPERUSER=1
  32.       - PHP_IDE_CONFIG=serverName=local-dev

One of the files being copied in this line: ${LOCAL_PATH}/docker/apache/conf.d:/usr/local/etc/php/conf.d is xdebug related meaning is the one enabling and setting up the extension.

Wonder if there is a way to tell Docker by using ARG or ENV variables to enable/disable xDebug while starting the container? Has anyone tried such thing before? If so can you help me with some ideas?

你可以根据构建参数简单地移动/重命名xdebug配置文件...或者类似这样的操作？

英文:

You could simply move/rename the xdebug conf file based on a build arg…

  1. FROM php:7.2-apache
  2. RUN apt-get update && apt-get install -y \
  3.         zlib1g-dev \
  4.         git \
  5.         unzip \
  6.     && rm -rf /var/lib/apt/lists/ \
  7.     && docker-php-ext-install zip pdo_mysql bcmath \
  8.     && a2enmod rewrite \
  9.     && pecl install xdebug-2.9.0 redis \
  10.     && docker-php-ext-enable xdebug redis \
  11.     && mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini" \
  12.     && mv /var/www/html /var/www \
  13.     && chown -R www-data:www-data /var/www/ \
  14.     && ln -s /usr/local/bin/php /usr/bin/php
  15. COPY --from=composer:1.9 /usr/bin/composer /usr/bin/composer
  17. RUN if [[ "$DISABLE_XDEBUG" == "1" ]] ; then mv "$PHP_INI_DIR/conf.d/xdebug.ini" "$PHP_INI_DIR/conf.d/xdebug.ini.disabled"
  19. WORKDIR /var/www/drm-case
  20. CMD ["docker/apache/bootstrap.sh"]

… or something like that?
