Xdebug

Contributed by dgoosens.

This procedure is similar to the one explained for AMPQ.

Debian Dockerfile

FROM jakzal/phpqa:debian AS ext-xdebug

RUN docker-php-source extract
RUN apt-get update
RUN apt-get install -qq -y build-essential autoconf 

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

RUN ls -al /usr/local/lib/php/extensions/

FROM jakzal/phpqa:debian

COPY --from=ext-xdebug /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
COPY --from=ext-xdebug /usr/local/lib/php/extensions/no-debug-non-zts-20210902/xdebug.so /usr/local/lib/php/extensions/no-debug-non-zts-20210902/xdebug.so

Alpine Dockerfile

FROM jakzal/phpqa:alpine AS ext-xdebug

RUN docker-php-source extract
RUN apk -Uu add autoconf build-base
RUN pecl install xdebug
RUN docker-php-ext-enable xdebug

RUN ls -al /usr/local/lib/php/extensions/

FROM jakzal/phpqa:alpine

COPY --from=ext-xdebug /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
COPY --from=ext-xdebug /usr/local/lib/php/extensions/no-debug-non-zts-20210902/xdebug.so /usr/local/lib/php/extensions/no-debug-non-zts-20210902/xdebug.so

About the extension path

Please note that the no-debug-non-zts-20210902 in the above extension path, that is copied, changes with every release... This is why the RUN ls -al /usr/local/lib/php/extensions/ is issued as it will list the content of that directory and inform the user what the exact path should be.

Note

If you need to include multiple extensions, you will have to bundle the commands together.
For instance, for AMPQ AND XDebug, the Debian Dockerfile will look like this:

FROM jakzal/phpqa:debian AS ext-multi
ENV EXT_AMQP_VERSION=master

RUN docker-php-source extract
RUN apt-get update
RUN apt-get install -qq -y build-essential autoconf 

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

# ampq
RUN apt-get install -qq -y librabbitmq-dev
RUN git clone --branch $EXT_AMQP_VERSION --depth 1 https://github.com/php-amqp/php-amqp.git /usr/src/php/ext/amqp
RUN cd /usr/src/php/ext/amqp && git submodule update --init
RUN docker-php-ext-install amqp


RUN ls -al /usr/local/lib/php/extensions/

FROM jakzal/phpqa:debian

# xdebug
COPY --from=ext-multi /usr/local/etc/php/conf.d/docker-php-ext-multi.ini /usr/local/etc/php/conf.d/docker-php-ext-multi.ini
COPY --from=ext-multi /usr/local/lib/php/extensions/no-debug-non-zts-20210902/xdebug.so /usr/local/lib/php/extensions/no-debug-non-zts-20210902/xdebug.so

# ampq
COPY --from=ext-amqp /usr/local/etc/php/conf.d/docker-php-ext-amqp.ini /usr/local/etc/php/conf.d/docker-php-ext-amqp.ini
COPY --from=ext-amqp /usr/local/lib/php/extensions/no-debug-non-zts-20210902/amqp.so /usr/local/lib/php/extensions/no-debug-non-zts-20210902/amqp.so
RUN apt-get update
RUN apt-get install -qq -y librabbitmq-dev
