[astros3]

$ docker run test-image php /usr/local/bin/test.php
Fatal error: Uncaught PDOException: SQLSTATE[HY000] [2002] Connection refused in /usr/local/bin/test.php:5

Chi è che rifiuta la connessione e perchè?
Inoltre quando do il comando

$ docker-compose up --build -d

mi appaiono una miriade di queste cose
