⁠from https://www.drupal.org/docs/8/system-requirements/drupal-8-php-requirements⁠

FROM php:7.4-fpm-buster

⁠TODO switch to buster once https://github.com/docker-library/php/issues/865⁠ is resolved in a clean way (either in the PHP image or in PHP itself)

⁠install the PHP extensions we need

RUN set -eux;

if command -v a2enmod; then
a2enmod rewrite;
fi;

savedAptMark="$(apt-mark showmanual)";

apt-get update;
apt-get install -y --no-install-recommends
libfreetype6-dev
libjpeg-dev
libpng-dev
libpq-dev
libzip-dev
curl
vim
git
;

docker-php-ext-configure gd
--with-freetype
--with-jpeg=/usr
;

docker-php-ext-install -j "$(nproc)"
gd
opcache

zip

⁠reset apt-mark's "manual" list so that "purge --auto-remove" will remove all build dependencies

apt-mark auto '.*' > /dev/null; \
apt-mark manual $savedAptMark; \
ldd "$(php -r 'echo ini_get("extension_dir");')"/*.so \
	| awk '/=>/ { print $3 }' \
	| sort -u \
	| xargs -r dpkg-query -S \
	| cut -d: -f1 \
	| sort -u \
	| xargs -rt apt-mark manual; \
\
apt-get purge -y --auto-remove -o APT::AutoRemove::RecommendsImportant=false; \
rm -rf /var/lib/apt/lists/*

⁠set recommended PHP.ini settings
