如何将laravel env连接到SQL Google Cloud？

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=your_database_name
DB_USERNAME=your_username
DB_PASSWORD=your_password

gcloud sql databases create your_database_name --instance=your_instance_name

gcloud sql users create your_username --instance=your_instance_name --password=your_password

'mysql' => [
    'driver' => 'mysql',
    'host' => '/cloudsql/your_project_id:your_region:your_instance_name',
    'port' => env('DB_PORT', '3306'),
    'database' => env('DB_DATABASE', 'forge'),
    'username' => env('DB_USERNAME', 'forge'),
    'password' => env('DB_PASSWORD', ''),
    'unix_socket' => env('DB_SOCKET', ''),
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
    'prefix' => '',
    'strict' => true,
    'engine' => null,
],

php artisan migrate
php artisan db:seed
