Why can't I run pdo_pgsql in my container? - postgresql

Question

I am trying to use AWS RDS postgresql from my php app. I have modified the Dockerfile to contain
RUN apt-get update && apt-get install -y libpq-dev && docker-php-ext-install pdo pdo_pgsql
But it doesn't seem to run. I think this because when I (finally) ran phpinfo() from the container, I don't see it loaded. I am assuming that when I run docker-compose up, the Dockerfile (that builds php-fpm) is run "automatically". Is that true? Here is the Dockerfile that doesn't seem to run:
FROM bitnami/php-fpm:7.2 as builder
RUN install_packages git autoconf build-essential
WORKDIR /app
RUN wget https://github.com/xdebug/xdebug/archive/2.6.0.tar.gz && \
tar xzf 2.6.0.tar.gz && \
cd xdebug-2.6.0 && \
phpize && \
./configure --enable-xdebug && \
make && make install
RUN apt-get update && apt-get install -y libpq-dev && docker-php-ext-install pdo pdo_pgsql
FROM bitnami/php-fpm:7.2
COPY --from=builder /opt/bitnami/php/lib/php/extensions/xdebug.so /opt/bitnami/php/lib/php/extensions/
RUN echo 'zend_extension="/opt/bitnami/php/lib/php/extensions/xdebug.so"' >> /opt/bitnami/php/etc/php.ini
RUN echo "xdebug.remote_port=9000" >> /opt/bitnami/php/etc/php.ini \
&& echo "xdebug.remote_enable=1" >> /opt/bitnami/php/etc/php.ini \
&& echo "xdebug.remote_connect_back=0" >> /opt/bitnami/php/etc/php.ini \
&& echo "xdebug.remote_host=192.168.122.1" >> /opt/bitnami/php/etc/php.ini \
&& echo "xdebug.idekey=docker" >> /opt/bitnami/php/etc/php.ini \
&& echo "xdebug.remote_autostart=1" >> /opt/bitnami/php/etc/php.ini \
&& echo "xdebug.remote_log=/tmp/xdebug.log" >> /opt/bitnami/php/etc/php.ini \
&& echo "extension=pgp_pdo_pgsql.so" >> /opt/bitnami/php/etc/php.ini \
&& echo "extension=pgp_pgsql.so" >> /opt/bitnami/php/etc/php.ini
And here is the docker-compose

If this Dockerfile is not being run automatically, how do I get it to create a new php-fpm container?

If you change Dockerfile and you want to update the image with docker-compose up, then you need to pass the flag --build with docker-compose up.
--build Build images before starting containers.
docker-compose up --build
