Alla fine ho risolto il problema, grazie @Dlk per il tuo aiuto.
La causa del problema era perché in database.php , mi riferivo all'host per mysql come localhost invece del nome del servizio MySQL in docker-compose.yml file. Quindi database.php il file dovrebbe apparire così :
<?php
$host = 'nairobi_mysql'; // Must be the service name of the database in `docker-compose.yml`
$db_name = 'nairobi';
$user = 'admin';
$pass = '123456';
$charset = 'utf8mb4'; // Always set charset for database
$port = '3306';
$dsn = "mysql:host=$host;dbname=$db_name;port=$port;charset=$charset";
$options = [
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
PDO::ATTR_EMULATE_PREPARES => false,
];
try {
$pdo = new PDO($dsn, $user, $pass, $options);
} catch (\PDOException $e) {
throw new \PDOException($e->getMessage(), (int)$e->getCode());
}
?>
che è correlato al mio docker-compose.yml file
