How to open the S3 interface of RADOS¶

The S3 interface is already configured and active.

In order to use it do as follows:

openstack --os-interface public ec2 credentials create

and take note of the access and secret keys.

When configuring the environment, the following informations are also needed:

name of the radosgw instance: http://swift.cloud.garr.it

// require the AWS SDK for php library
require '/home/galeazzi/phpScript/aws-autoloader.php';

use Aws\S3\S3Client;
