I'm facing some missing extensions

[marcosfreitas]

Hi Guys, thanks for your amazing work on this project.

I have an image based on php7.4-fpm-alpine that uses this script to install some extensions. By default, the GD and Imagick are installed.

Today I got some errors when handling a composer update and to my surprise:

• 🐛 the gd ext is showing as not installed, but php -m lists it.
• 🐛 there is a php8 located at /etc an I don't know why

I wondering how this php8 goes there and if it is causing some conflict in compose.

• 👎🏻 I'd check the base image but there doesn't exist any php8 binary installed.
• 👎🏻 I rebuilt my image but the problem continues and I have no instructions to work with PHP 8.

So, basically, I have two PHP versions installed and some missing extensions. Any Ideas?

My image:

I've some descriptions here

Alpine base image:

Seems that running this command makes that php8 has been installed. Without it, php7 version remains.

apk add --no-cache shadow bash composer &&\
composer self-update --2

I'm still investigating about the missing extensions conflict.

Maybe installing composer with apk causes apk to install PHP? And that's absolutely wrong: in the docker php images, PHP is compiled from source: you must not install it (or any PHP extension, or any package that depends on PHP) with apk.
The solution? Don't install composer with apk, and read https://github.com/mlocati/docker-php-extension-installer#installing-composer

Yeah, you are right. I saw this capability yesterday reading the docs but I don't remember to saw it before.

The curious part is that the composer is being installed this way a long time ago and I didn't have this problem before.

I think I was getting an outdated version of something... never mind.

I'm changing the installation and I will put a status here.
