SOLVED
After watching videos about ngnix, I thought - ok, I have mariadb, phpMyAdmin to manage the DB and “web” with PHP, but where’s the apache actually or ngnix in this config to handle the traffic? I added image: php:8.2-apache
instead of image: php:8.2-cli
and voila - hello world in browser.
And there’s also AdBlock plugin in OpenWRT
