Debug your PHP in Docker with Intellij/PHPStorm and Xdebug

1. For your local dev, create a Dockerfile that is based on your production image and simply install xdebug into it. Exemple:

FROM php:5

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 \

# Remote all exited container
docker rm $(docker ps -q -f status=exited)

# Remote none tag images (image with tag <none>)
docker images | grep "<none>" | awk '{print $3}' |xargs docker rmi -f

# Remove all images that is not using by any running container
# note: docker ps --format {{.Image} -> List all images of running container then set it as grep pattern

#I have these two aliases defined that I find very useful:
