PHP7-FPM Restart – How to Restart php7-fpm with Supervisord

I have a custom docker image for apache and php7-fpm but whenever i make changes to the php ini file and use supervisord to retsart php7-fpm after those changes during image building before running the container from the image i noticed i have been unable to make php7-fpm restart. So the changes i make to the php ini file never gets reflected

But when i log into the running container and try to retsart php7-fpm then i see those changes

Here is what my supervisord config has

[supervisord]
nodaemon=true

[program:php-fpm7.0]
command = /usr/sbin/php-fpm7.0 -c /etc/php/7.0/fpm/php-fpm.conf
autorestart=true

[program:apache2]
command=/bin/bash -c "source /etc/apache2/envvars && exec /usr/sbin/apache2 -DFOREGROUND"
autorestart=true

Here is my start.sh script

#!/bin/bash
set -e
echo "ServerName localhost" >> /etc/apache2/apache2.conf
#echo "export HOSTNAME=$(hostname)" >> /etc/apache2/envvars
sed -i -e "s/;cgi.fix_pathinfo=1/cgi.fix_pathinfo=0/g" /etc/php/7.0/fpm/php.ini

Please help with how to restart php7-fpm when changes are made to the php ini file with a start.sh script while creating the docker image

P.S.

You may be wondering why do i need to restart php7-fpm if it only needs to be started, well no way to get php7-fpm to work with docker except i actually start it first in my docker file like below. Whenever i remove that line from my dockerfile, it does not work. If anyone has apache 2.4 and php7-fpm setup in docker that works without that way PLEASE send me the link to their image!

RUN service php7.0-fpm start

Thanks
