Dockerfile reducing RUNs

[yohancourbe]

From my understanding of Docker - I'm not a guru - each time you use a RUN command, it creates a temporary cached image. In this case, I think there are way to many RUNs

# 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_connect_back=1" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
RUN echo "xdebug.idekey=\"PHPSTORM\"" >> /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

could be written

# install xdebug
RUN pecl install xdebug \
&& docker-php-ext-enable xdebug \
&& echo "error_reporting = E_ALL" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini \
&& echo "display_startup_errors = On" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini \
&& echo "display_errors = On" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.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=9001" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini

which would result in a single subimage created.

I'm keen to contribute.

cheers
