## The Dockerfile
Only add the `xdebug.remote_log` line if you need to troubleshoot.

```
FROM php:7.1-apache

RUN yes | pecl install xdebug \
    && echo "zend_extension=$(find /usr/local/lib/php/extensions/ -name xdebug.so)" > /usr/local/etc/php/conf.d/xdebug.ini \
    && echo "xdebug.remote_enable=1" >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo "xdebug.remote_autostart=1" >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo "xdebug.remote_host=172.17.0.2" >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo "xdebug.remote_log=/var/www/html/xdebug.log" >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo "xdebug.remote_connect_back=1" >> /usr/local/etc/php/conf.d/xdebug.ini \
    && echo "xdebug.remote_port=9000" >> /usr/local/etc/php/conf.d/xdebug.ini
