```bash
$ composer install kreait/gcp-metadata
```

```php
$metadata = new \Kreait\GcpMetadata();
```

#### Check if the metadata server is available

```php
$isAvailable = $metadata->isAvailable();
```

#### Get all available instance properties

$data = $metadata->instance();
```

#### Get all available project properties

$data = $metadata->project();
```

#### Access a specific property

$data = $metadata->instance('hostname');
```

#### Wrap queries in a try/catch block if you don't check for availability

```php
if ($metadata->isAvailable()) {
    echo $metadata->instance('hostname');
}

try {
    echo $metadata->instance('hostname');
catch (\Kreait\GCPMetadata\Error $e) {
    echo $e->getMessage();
}
```
