Question

I am trying to get xdebug to work in a php container within a docker-compose setup. I found a few examples that show the extra config lines that need to be added to the container:

From Reddit, I have tried to add these lines in my web container's Dockerfile:

    # Configure xdebug
    RUN echo "xdebug.remote_enable=1" >> /etc/php5/fpm/conf.d/20-xdebug.ini
    RUN echo "xdebug.idekey=PHPSTORM" >> /etc/php5/fpm/conf.d/20-xdebug.ini
    RUN echo "xdebug.remote_connect_back=1" >> /etc/php5/fpm/conf.d/20-xdebug.ini
    RUN echo "xdebug.remote_host=10.10.1.2" >> /etc/php5/fpm/conf.d/20-xdebug.ini

But I am not directly using a dockerfile as far as I can tell.

    my docker-compose.yml:

    web:
      image: tutorial/nginx
      ports:
        - "8080:80"
      volumes:
        - ./src:/var/www
        - ./src/vhost.conf:/etc/nginx/sites-enabled/vhost.conf
      links:
        - php

    php:
      image: nmcteam/php56
      volumes:
        - ./src/php-fpm.conf:/etc/php5/fpm/php-fpm.conf
        - ./src:/var/www
      run:
        # Configure xdebug
        RUN echo "xdebug.remote_enable=1" >> /etc/php5/fpm/conf.d/20-xdebug.ini
        RUN echo "xdebug.idekey=PHPSTORM" >> /etc/php5/fpm/conf.d/20-xdebug.ini
        RUN echo "xdebug.remote_connect_back=1" >> /etc/php5/fpm/conf.d/20-xdebug.ini
        RUN echo "xdebug.remote_host=10.10.1.2" >> /etc/php5/fpm/conf.d/20-xdebug.ini
      links:
        - db

    db:
      image: sameersbn/mysql
      volumes:
       - /var/lib/mysql
      environment:
       - DB_NAME=demoDb
       - DB_USER=demoUser
       - DB_PASS=demoPass

Clearly the run: section does not work. I'm missing something, but so far have not been able to get my head around how to solve the problem using compose.

run不是docker-compose

中的命令

您可以使用image

的替代路径指定build或Dockerfile

因此，您可以在RUN中使用Dockerfile。 Reference

我的建议是，如果你需要运行你指定的命令，你可以为你的'php'Dockerfile执行类似的操作：

FROM nmcteam/php56
RUN echo "xdebug.remote_enable=1" >> /etc/php5/fpm/conf.d/20-xdebug.ini
RUN echo "xdebug.idekey=PHPSTORM" >> /etc/php5/fpm/conf.d/20-xdebug.ini
RUN echo "xdebug.remote_connect_back=1" >> /etc/php5/fpm/conf.d/20-xdebug.ini
RUN echo "xdebug.remote_host=10.10.1.2" >> /etc/php5/fpm/conf.d/20-xdebug.ini

构建图像：

docker build -t myuser/php56 <path to Dockerfle>

然后在你的docker-compose.yml文件中，在'php'部分：

php:
  image: myuser/php56
  volumes:
    - ./src/php-fpm.conf:/etc/php5/fpm/php-fpm.conf
    - ./src:/var/www
  links:
    - db

您可以选择将图片推送到dockerhub帐户：

docker push myuser/php56

Updating a config file through docker-compose
