The official documentation can be found here.

Set the default value in the Dockerfile for php.ini

Default value (local value)

pdo_mysql.default_socket

is null.
I want to address Dockerfile when it comes up
enter image description here

My DockerFile:

FROM php:7.4-fpm
RUN apt-get -y update 
        && apt-get install -y libicu-dev 
                libxml2-dev 
                libzip-dev 
                libpng-dev 
                libwebp-dev 
                libjpeg-dev 
                libxpm-dev 
                libfreetype6-dev 
                libjpeg62-turbo-dev 
                zip 
                unzip 
                nano 
        && docker-php-ext-configure gd --enable-gd --with-webp --with-jpeg --with-freetype 
        && docker-php-ext-configure intl 
        && docker-php-ext-install mysqli intl pdo pdo_mysql soap opcache zip gd bcmath sockets

    I found the solution:

    first create the custom-php.ini and set value such as:

    [php]
pdo_mysql.default_socket=/var/run/mysqld/mysqld.sock

    Then we add this file to Docker example

    ADD ./custom-php.ini /usr/local/etc/php/conf.d/custom-php.ini

    You are installing but not enabling it.
    Please add additional RUN command into your Dockerfile:

    RUN docker-php-ext-install mysqli && docker-php-ext-enable mysqli

    As stated from documentations, PHP extensions need to be both installed and enabled: https://hub.docker.com/_/php
