Updating a config file through docker-compose

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 is not a command in docker-compose

you can specify either image or build with alternative path to a Dockerfile

So you can use RUN in your Dockerfile. Reference

My recommendation is that if you need to run the commands you specified, you can do something like this for your 'php' Dockerfile:

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

Build the image:

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

Then in your docker-compose.yml file, in the 'php' section:

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

You can optionally push your image to your dockerhub account:

docker push myuser/php56
