Connect to Xdebug running inside your PHP Container by building an image with Xdebug installed and running like this: `docker-compose -f docker-compose.xdebug.yml up`. Then the PHP inside your editor will connect to Xdebug running in your editor.

.env

DOCKER_HOST_IP=IP.OF.YOUR.HOST.MACHINE.FROM.INSIDE.DOCKER

Dockerfile.xdebug

FROM FROM php:7.0-apache

RUN pecl install xdebug

ARG HOST_IP

# set recommended PHP.ini settings
# see https://secure.php.net/manual/en/opcache.installation.php
RUN { \
      echo '[xdebug]'; \
      echo "zend_extension=$(find /usr/local/lib/php/extensions/ -name xdebug.so)"; \
      echo 'xdebug.remote_enable=1'; \
      echo 'xdebug.remote_autostart=1'; \
      echo 'xdebug.remote_log="/tmp/xdebug.log"'; \
      echo "xdebug.remote_host=$HOST_IP"; \
    } > /usr/local/etc/php/conf.d/xdebug.ini
