PHP Extensions are not properly installing with docker composer yml file

Question

I tried to install GD Extension in docker with the following command, But it is not installing. Can you please suggest where is the issue? Following is the code in Dockerfile. I would like to install more php extensions like zip also. but am not getting any errors also, when am using composer update command itself

Codes in Dockerfile
FROM php:7.4-apache
RUN apt-get update && apt-get install -y \
        libfreetype6-dev \
        libjpeg62-turbo-dev \
        libpng-dev \
    && docker-php-ext-configure gd --with-freetype --with-jpeg \
    && docker-php-ext-install -j$(nproc) gd

Try php7.4-gd instead of just gd and put it before docker-php-ext-configure — kopz, Feb 22 '23 at 06:22
@kopz phpinfo() is saying that GD is not installed. I have also checked with php-m to get the list of installed commands, and it also not listing GD — Xavier Issac, Feb 22 '23 at 07:04

I have faced same issue on php:alpine image when command php -m returned that all php extensions were installed and enabled but when run composer show -p it's been seen that there were missing php extensions.

I followed answer to question How to install PHP composer inside a docker container and installed composer with next step in Dockerfile:

RUN curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer

After that running composer show -p gave output with all installed php extensions.

PHP Extensions are not properly installing with docker composer yml file
