An exception occurred in driver: SQLSTATE[HY000] [2002] Connection refused

Hello.

'm attempting to install a Wallabag Docker container on an Almalinux 8 system that already has a MariaDB 10.5 container running smoothly with other internal network services.

However, I encountered the following error during the installation process.:

`FAILED! => {"changed": false, "elapsed": 300, "msg": "Timeout when waiting for mariadb:32768"}` **32768** is the exposed port of my Mariadb

f I execute the command `sudo docker exec -t wallabag /var/www/wallabag/bin/console wallabag:install --env=prod --no-interaction` I get the error below:

```
