Bigger docker image size using this tool #753

Hello! I recently found out about your tool, love the simplicity! ❤️ But I have a question...

Since I care a lot about docker image sizes, it's a big deal for me
(even though the official PHP docker image has reached 100mb recently 😢)

I wanted to use the Relay extension and their docs offered either your tool or some complicated way of installation, unlike any other extensions I used.
I've been using my own script for extension installations, been improving it for a year now, using the tools that offer official PHP images.

So I decided to compare the sizes of the docker image with my script and your tool. Grabbed the script straight from my project and specified the same extensions for your tool.

Below are some proofs

Images and layers

Images side-by-side

Layer sizes (my script)

Layer sizes (your tool)

The difference is no less than 26MB, I also had 31MB with Relay installed. Not a huge number but still a pretty big

Installed extensions (php-m) for both (they were equal)

[PHP Modules] apcu
Core
ctype
curl
date
dom
fileinfo
filter
ftp
hash
iconv
intl
json
libxml
mbstring
mysqlnd
openssl
pcntl
pcre
PDO
pdo_mysql
pdo_sqlite
Phar
posix
random
readline
redis
Reflection
session
SimpleXML
sodium
SPL
sqlite3
standard
tokenizer
xml
xmlreader
xmlwriter
zip
zlib

Surprisingly they're equal, furthermore, my script has +1 package installed (icu-73.1-r1 x86_64)

Dockerfiles

Dockerfile with my script:

FROM php:8.2-fpm-alpine

RUN apk add --no-cache -t .extension-deps \
    icu libzip

RUN set -xe \
    && apk add --no-cache -t .build-deps $PHPIZE_DEPS \
    icu-dev libzip-dev \
    && pecl install -f apcu-5.1.22 redis-5.3.7 \
    && docker-php-source extract \
    && docker-php-ext-configure intl \
    && docker-php-ext-configure pcntl --enable-pcntl \
    && docker-php-ext-install -j$(nproc) pdo pdo_mysql intl pcntl zip \
    && docker-php-ext-enable apcu redis \
    && docker-php-source delete \
    && pecl clear-cache \
    && rm -rf /tmp/* \
    && apk del --purge .build-deps

Dockerfile with your tool:

FROM php:8.2-fpm-alpine

COPY --from=mlocati/php-extension-installer /usr/bin/install-php-extensions /usr/local/bin/

RUN install-php-extensions apcu intl pcntl pdo_mysql redis zip \
    && rm -rf /usr/local/bin/install-php-extensions

I don't see anything that could've told me the reason for such a difference, maybe you know?
Also, I only have seen #241 in this repo mentioning the size difference, so maybe I'm doing something wrong?
