Open php.ini in docker compose to add an extension – Phpmyadmin

I am using docker compose, I want to open few extensions and edit. So basically I want to open php.ini file. How can we exactly do that. However some solutions I read are saying to do changing in docker_compose.yaml, I am also sharing the file.
I am using php laravel framework, and running application on ubuntu server. Any help is highly appreciated.
Thanks in advance.
docker_compose.yaml look something like this.

version: '3.7'

services:
    php:
        container_name: eesotne-fpm
        build: ./deployment/fpm

    You need to create your custom image.

    Not sure about how you are building your images but it seems you already have your docker files with your specifications.

    If you are using an official image as base image to enable the image it is very easy in the construction of the docker image.

    To configure the php.ini the good practice is have a preconfigured php.ini and copy it to the image to replace the default.

    FROM php:7.3-fpm
RUN docker-php-ext-install pdo pdo_mysql opcache
COPY config/php.ini /php.init
RUN mv /php.ini "$PHP_INI_DIR/php.ini"

    Hope this can help.

    Another dirty method could be update your php.ini with a shell script using the sed command to replace with your values.

    You mentioned some solutions require you to edit your docker-compose file, but I’m not entirely sure if that’s an issue for you based on your post.

    You could map a volume to a local directory and give yourself free rein to add any PHP configuration in the future. If your container is based on the official image, you can do something like this:

    volumes:
- ./php-conf:/usr/local/etc/php/conf.d

    Which would map your local php-conf directory to the directory configured to scan for more .ini files. You can also override this with the PHP_INI_SCAN_DIR env variable:

    It is possible to configure PHP to scan for .ini files in a directory after reading php.ini. This can be done at compile time by setting the –with-config-file-scan-dir option. In PHP 5.2.0 and later, the scan directory can then be overridden at run time by setting the PHP_INI_SCAN_DIR environment variable.

    In there you can put whatever configuration you’d like to override in .ini files.
