Can't install pdo_mysql with docker-php-ext-install - php

Question

I need help, I can’t install pdo_mysql, ampq or opcache with docker-php-ext-install. I prepared a docker project on a local PC (Mac OSX). On the local PC after build docker image is the final PHP configuration right. When I deploy the project config to the remote Debian server after building it, I have a completely different PHP version (phpinfo). Missing extensions opcache, pdo_mysql, ampq.
I tried to configure it differently and deleted the docker cache on the server, but it didn’t help.
docker system prune -a
My PHP dockerfile:
FROM php:7.4-fpm

Not sure if it's a solution to your issue, but let's see.
From https://hub.docker.com/_/php:
If you are having difficulty figuring out which Debian or Alpine packages need to be installed before docker-php-ext-install, then have a look at the install-php-extensions project. This script builds upon the docker-php-ext-* scripts and simplifies the installation of PHP extensions by automatically adding and removing Debian (apt) and Alpine (apk) packages. For example, to install the GD extension you simply have to run install-php-extensions gd. This tool is contributed by community members and is not included in the images, please refer to their Git repository for installation, usage, and issues.
I had similar issues in the past and resolved it by using install-php-extensions. See this comment.
