デプロイツールでよくあるEC2のRoleを元にデプロイ先のIPを取得する感じです。

require_once(realpath(__DIR__ ."/../vendor/autoload.php")); // 別の階層で利用するので

use Aws\Ec2\Ec2Client;

$keys = array(
		'key'	=> '**********************',
		'secret' => '*********************************',
	);
$config = array(
	'credentials' => $keys,
	'region' => 'ap-northeast-1',
	'version' => 'latest',
);

$ec2 = new Ec2Client($config);
$instances = $ec2->describeInstances(array(
	'Filters' => array(
		array(
			'Name' => 'instance-state-name','Values' => array('running'),
		),
	),
));

$role = 'app'; // 探したいRole
$hosts = array();
$reservations = $instances['Reservations'];
foreach ($reservations as $reservation) {
	$instances = $reservation['Instances'];
	foreach ($instances as $instance) {
		foreach ($instance['Tags'] as $tag) {
			if ($tag['Key'] === 'Role') {
				if ($tag['Value'] === $role) {
					$hosts[] = $instance['PrivateIpAddress'];
					break;
				}
			}
		}
	}
}

var_dump($hosts);
