I am using Docker to run my old Wordpress project. After migrating on Docker i get this error:
Fatal error: Uncaught Error: Call to undefined function mysql_connect() in
/var/www/html/wp-includes/wp-db.php:1570 Stack trace:

I tried following things: - add MySQL extensions to Dockerfile - remove plugins - change theme But without success.
