PHP Extensions are disabled by default using Docker - php

Question

I'm developing a Laravel application using Docker. I use multiple containers for different services; App (PHP), Webserver (Nginx), Relational Database (MySql) and In-Memory Database (Redis).
I've written a Dockerfile for App service using php:8.1-fpm as the base image. The problem is when I bring up the container and go to /usr/local/etc/php folder to check the installed extensions (I tried to use FFI extension and it turned out that it is disabled), I found two files: php.ini-development and php.ini-production. When I executed cat command on them, I found out that almost all the extensions are disabled by default in both of them.
So my question is do I need to enable them myself each time I bring up the container? Isn't there a better way?
Here is my Dockerfile:
FROM php:8.1-fpm
# Copy composer.lock and composer.json
COPY composer.lock composer.json /var/www/
# Set working directory
WORKDIR /var/www
# Install dependencies

And Here is the first part of php.ini-development file (As it is a long file, I didn't copy all lines of the file):
