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

Start with the provided docker-compose configuration and the installer entry point referenced in InstallCommand.php line 337. Trace the cache:clear failure through AbstractMySQLDriver.php line 112 and PDOConnection.php line 40, then verify the MariaDB connection settings and rerun the wallabag installer. Done means the database setup and cache-clearing steps complete without the connection-refused error.

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:
