Missing extensions?

[Synchro]

I read #94 and assumed that it would auto-install PHP extensions depending on the ext- options in composer.json, but it doesn't seem to be working for me in my gitlab workflow. Instead I get:

Using docker image sha256:6e10fb20dffb5507d748d3890244fa471476b98e7576d760076de00b07e44607 for lorisleiva/laravel-docker:8.0 with digest lorisleiva/laravel-docker@sha256:68dedfc04c88d6b7633260d3d0b2428f168c16e81b56721e8217093158f94910 ...

60    - Root composer.json requires PHP extension ext-mysqli * but it is missing from your system. Install or enable PHP's mysqli extension.
61To enable extensions, verify that they are enabled in your .ini files:
62    - 
63    - /usr/local/etc/php/conf.d/docker-php-ext-bcmath.ini
64    - /usr/local/etc/php/conf.d/docker-php-ext-calendar.ini
65    - /usr/local/etc/php/conf.d/docker-php-ext-exif.ini
66    - /usr/local/etc/php/conf.d/docker-php-ext-gd.ini
67    - /usr/local/etc/php/conf.d/docker-php-ext-imagick.ini
68    - /usr/local/etc/php/conf.d/docker-php-ext-intl.ini
69    - /usr/local/etc/php/conf.d/docker-php-ext-pcntl.ini
70    - /usr/local/etc/php/conf.d/docker-php-ext-pdo_mysql.ini
71    - /usr/local/etc/php/conf.d/docker-php-ext-pdo_pgsql.ini
72    - /usr/local/etc/php/conf.d/docker-php-ext-redis.ini
73    - /usr/local/etc/php/conf.d/docker-php-ext-soap.ini
74    - /usr/local/etc/php/conf.d/docker-php-ext-sodium.ini
75    - /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
76    - /usr/local/etc/php/conf.d/docker-php-ext-zip.ini
77You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

My composer.json contains:

    "require": {
        "php": "^8.0",
        "ext-exif": "*",
        "ext-gd": "*",
        "ext-imagick": "*",
        "ext-mysqli": "*",
        "ext-pdo": "*",
        "ext-pdo_mysql": "*",
        "ext-sodium": "*",

which I note does not include some of the extensions listed in the error, though I guess they may pulled in by deps.

Is there something else I need to do?

I managed to solve this by adding a line to my composer stage's script:

- install-php-extensions mysqli

however, I was under the impression that this image had some kind of mapping that would automatically enable extensions listed in the composer.json file?
