Docker: How to install PHP 7.4 extension ext-http? - php

Question

I would like to install the ext-http extension because I have this error when I execute composer install command in my php-apache container:
The requested PHP extension ext-http * is missing from your system.
Install or enable PHP's http extension.
My Dockerfile:
ARG PHP_VERSION=""
FROM php:${PHP_VERSION}-apache
ENV COMPOSER_ALLOW_SUPERUSER=1
EXPOSE 80
WORKDIR /${PROJECT_DIRECTORY}
# git, unzip & zip are for composer
RUN apt-get update -qq && \
apt-get install -qy \
git \
gnupg \
libfreetype6-dev \
libjpeg62-turbo-dev \
libmcrypt-dev \
libicu-dev \
libxml2-dev \
wget \
nano \
unzip \
zip && \
curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer && \
apt-get clean && rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*
# PHP Extensions
RUN docker-php-ext-install -j$(nproc) opcache pdo_mysql intl xml soap
ADD php/php.ini /usr/local/etc/php/conf.d/${PROJECT_DIRECTORY}.ini
# Apache
RUN a2enmod rewrite remoteip
ADD vhosts/vhost.conf /etc/apache2/sites-available/000-default.conf
I have "ext-http": "*" in require node of my composer.json.
I tried:
RUN docker-php-ext-install -j$(nproc) opcache pdo_mysql intl xml soap ext-http
And I have this error:
Step 7/10 : RUN docker-php-ext-install -j$(nproc) opcache pdo_mysql

Some of the above modules are already compiled into PHP; please check
the output of "php -i" to see which modules are already loaded. ERROR:
Service 'apache' failed to build: The command '/bin/sh -c
docker-php-ext-install -j$(nproc) opcache pdo_mysql intl xml soap
ext-http' returned a non-zero code: 1 Failed to deploy 'Compose:
.docker': docker-compose process finished with exit code 1
How can I install this extension please?

Answer 1

I published a script that lets you install the http PHP extension (and many others) with just these lines:
ADD https://github.com/mlocati/docker-php-extension-installer/releases/latest/download/install-php-extensions /usr/local/bin/
RUN chmod +x /usr/local/bin/install-php-extensions && sync && \
install-php-extensions http
the script takes care of the PHP version, and installs all the required APT (for Debian) or APK (for Alpine) packages.

You might want to install it via pecl. The http extension also has dependencies.
RUN docker-php-ext-install hash iconv \
&& pecl install raphf propro \
&& docker-php-ext-enable raphf propro \
&& pecl install pecl_http \
&& echo -e "extension=raphf.so\nextension=propro.so\nextension=http.so" > /usr/local/etc/php/conf.d/docker-php-ext-http.ini \
&& rm -rf /usr/local/etc/php/conf.d/docker-php-ext-raphf.ini \
&& rm -rf /usr/local/etc/php/conf.d/docker-php-ext-propro.ini
