proophessor-do: Unable to instantiate xdebug

Hi,

For me it was hard to set it up too, because of the configuration of the remote connection. I use php:7.1-fpm, but I suppose it will be similar for you.

This is my configuration:

.env file:

# Host Local IP (for Xdebug)
HOST_IP=docker.for.mac.localhost

# Server name (for Xdebug in CLI)
PHPSTORM_SERVER_NAME=www.project.localhost

The relevant part of my docker-compose.yml file, the one that refers to the PHP container:

    php:
        container_name: project-php
        build:
            context: docker/php7-fpm
            args:
                HOST_IP: ${HOST_IP}
                PHPSTORM_SERVER_NAME: ${PHPSTORM_SERVER_NAME}
        volumes:
            - ./docker/logs/symfony:/var/www/${SYMFONY_APP_NAME}/var/logs:cached
            - ${SYMFONY_APP_PATH}/vendor:/var/www/${SYMFONY_APP_NAME}/vendor:cached
            - ${SYMFONY_APP_PATH}:/var/www/${SYMFONY_APP_NAME}

And the relevant part of my Dockerfile:

FROM php:7.1-fpm

ARG PHPSTORM_SERVER_NAME
ARG HOST_IP

...

# install xdebug
RUN pecl install xdebug
RUN docker-php-ext-enable xdebug
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.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_connect_back=0" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN echo "xdebug.remote_port=9001" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN printf "xdebug.remote_host=%s" ${HOST_IP} >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini

RUN printf '\nexport PHP_IDE_CONFIG="serverName=%s"\n' ${PHPSTORM_SERVER_NAME} >> ~/.bashrc

Then, my xdebug configuration in PHPStorm is as follows:

The configuration for xdebug:

And the configuration for server —it is a Symfony 3.4 application, it may differ for you—:

Hope it helps!

Regards!

@rubenrubiob Thank you for the comment!

I was about to try that today, as I said to @codeliner in Gitter yesterday, building xdebug from pecl should do the trick and you prove me correct as it works now!

@codeliner in regards to issue #161 maybe instead of cloning xdebug source and compile it, just to install pecl extension? Because other than that I don’t see any difference that could cause the issue 😦

Thanks again @rubenrubiob for taking the time to help!

I didn’t changed anything from my previous settings, all I did was changing my docker-compose.yml and add Dockerfile and then run $ docker-compose up -d and xdebug now works fine!

./docker-compose.yml file (only php section):

  php:
    image: prooph/php:7.1-fpm
    build:
      context: .
      dockerfile: Dockerfile
    restart: always
    volumes:
      - ./etc/xdebug.log:/tmp/xdebug.log
      - "./etc/xdebug-custom.ini:/usr/local/etc/php/conf.d/xdebug-custom.ini"
      - .:/var/www
    depends_on:
      - mysql
      - mongodb
    environment:
      PROOPH_ENV: "development"
      XDEBUG_CONFIG: "remote_connect_back=0"
      PHP_IDE_CONFIG: "serverName=prooph-docker"
      PHP_XDEBUG_ENABLED: 1

./Dockerfile:

FROM php:7.1-fpm

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

et voilà! xdebug now works! 😃

@sandrokeil, without knowing the exact reason behind that but yes, pecl install xdebug solve this issue for me. Also, that happened to me in the past as well, when I was in the mood that everything needs to be compiled from source in order to work best with your OS, and xdebug never worked for me. And by saying past I go back in Mac OS X Leopard edition, I stopped trying to find the solution since Mavericks, but pecl always was working for some reason.

Also, I had clean install almost every-time after new OS version and I had a new Macbook Pro machine somewhere down the road, thus I don’t think that it is something related to my setup.

Would be cool to know why compiling xdebug from source is not working, but even if I won’t find out about it I can live with it haha

@rubenrubiob yeah indeed it is! Hope this topic will help others as well! Lot’s of information here for Docker+Mac users 😄
