Docker file installing wrong php - php

Question

I have a laravel/php docker image that I updated to PHP 8.1 - I am now trying to go back to our project version 7.3 and won't work.
here's my YAML
###############################################################################

and here's my Dockerfile

I have deleted docker cache & containers and ran:
docker-compose up -d --force-recreate --build
But I do see "59bf1c3509f3 Already exists " in the build while it's running. And after it's finished I have the latest version of PHP 8.13
So could it be a different cache somewhere else I am not clearing? Or how can I force install of PHP 7.2 o 7.3

apt is the package manager for Debian based distribution. Use apk to manage software packages on Alpine Linux. See How to use this image.
