Trying to debug PHP from IntelliJ on Windows 10.

These are the first lines in my Dockerfile:

FROM drupaldocker/php:7.1-apache

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

I tried copying and pasting configuration from several sources, e.g.:

&& echo "error_reporting = E_ALL" > /usr/local/etc/php/php.ini \
&& echo "display_startup_errors = On" >> /usr/local/etc/php/php.ini \
&& echo "display_errors = On" >> /usr/local/etc/php/php.ini \
&& echo "xdebug.remote_enable=1" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini \
&& echo "xdebug.remote_connect_back=1" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini \
&& echo "xdebug.idekey=\"PHPSTORM\"" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini \
&& echo "xdebug.remote_port=9000" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini \
&& echo "xdebug.remote_connect_back=0" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini

The result is always the same.

I start the container via docker-compose and map port 9000 to localhost:9000 using the following line in compose yml.

ports:
    - "9000:9000"

When I try to start listening from IntelliJ I get the error: Port 9000 is busy.

I tried telnet 127.0.0.1 9000 I get the message: connection closed by foreign host.

Any idea what could be wrong?

    1) "I start the container and map port 9000 to localhost:9000" WHY? It's xdebug that connect to IDE and not other way around ... so why opening it in Docker? (please read the xdebug basics) 2) Why do you have 2 different occurrences of xdebug.remote_connect_back rule? 3) BTW -- remote_connect_back most likely will not work and you will need to specify the remote_host manually (the IP where IntelliJ is running). 4) stackoverflow.com/q/44032296/783119 .. or the link that TarunLalwani provided Commented Sep 24, 2017 at 10:59
  • >> "I start the container and map port 9000 to localhost:9000" please describe how you map the ports (I think the problem is somewhere here) Commented Sep 24, 2017 at 11:01
  • You need to connect form inside of a Docker (from xDebug) to localhost:9000 (to server upped by IntelliJ): stackoverflow.com/questions/24319662/… . Also see links in comments above. Commented Sep 24, 2017 at 11:10
  • edited to add the lines of compose yml that I've used to map ports Commented Sep 24, 2017 at 11:23
