'Loading custom php.ini on Docker (image: php:8.1.2-apache)

I'm trying to load my custom .ini file

I've tried mounting the /usr/local/etc/php/conf.d directory to ./php so that I can add .ini files, but it doesn't work, I mean the local directory php gets created but it's empty.

One more thing I'm curious about, what if the same config already exists in any of those already loaded .ini file, will my custom .ini will overwrite those? (That's actually what I want).

This is my Dockerfile

FROM php:8.1.2-apache

RUN apt-get update

# 1. development packages
RUN apt-get install -y \
    git \
    zip \
    curl \
    sudo \
    unzip \
    libicu-dev \
    libbz2-dev \
    libpng-dev \
    libjpeg-dev \
    libmcrypt-dev \
    libreadline-dev \
    libzip-dev \
    libfreetype6-dev \
    g++


# 2. apache configs + document root
ENV APACHE_DOCUMENT_ROOT=/var/www/html/public
RUN sed -ri -e 's!/var/www/html!${APACHE_DOCUMENT_ROOT}!g' /etc/apache2/sites-available/*.conf
RUN sed -ri -e 's!/var/www/!${APACHE_DOCUMENT_ROOT}!g' /etc/apache2/apache2.conf /etc/apache2/conf-available/*.conf


# 3. mod_rewrite for URL rewrite and mod_headers for .htaccess extra headers like Access-Control-Allow-Origin-
RUN a2enmod rewrite headers


# 4. start with base php config, then add extensions
RUN mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini"

RUN docker-php-ext-install \
    bz2 \
    intl \
    iconv \
    bcmath \
    opcache \
    calendar \
    pdo_mysql \
    pdo_mysql \
    zip

# 5. composer
COPY --from=composer:latest /usr/bin/composer /usr/bin/composer

And here's the docker-compose.yml

version: '3.5'

services:

  # Laravel App
  laravel:
    build:
      context: '.'
    restart: always
    volumes:
      - .:/var/www/html
      # - ./php:/usr/local/etc/php/conf.d  (This doesn't work)

  # MySQL
  mysql:
    image: mysql:8
    restart: always
    volumes:
      - ./run/var:/var/lib/mysql
    environment:
      - MYSQL_DATABASE=${DB_DATABASE}
      - MYSQL_PASSWORD=${DB_PASSWORD}
      - MYSQL_ROOT_PASSWORD=${DB_PASSWORD}

  # Meilisearch
  meilisearch:
    image: getmeili/meilisearch:latest
    restart: always
    volumes:
      - ./meilisearch/data.ms:/data.ms
    environment:
    - MEILI_MASTER_KEY=${MEILISEARCH_KEY}

networks:
  default:
    name: nginxproxymanager_default
    external: true

Many thanks in advance :)

Set path direct to file

    volumes:
      - ./:/var/www
      - ./Docker/php/local.ini:/usr/local/etc/php/conf.d/local.ini

Check my docker-compose for more information: https://github.com/JavierAgueroCL/docker-php7.4-with-db-extensions/blob/master/docker-compose.yml
