            • ‘deviceName’<~String> - specifies how volume is exposed to instance

            • ‘status’<~String> - status of attached volume

            • ‘volumeId’<~String> - Id of attached volume

          • ‘dnsName’<~String> - public dns name, blank until instance is running

          • ‘imageId’<~String> - image id of ami used to launch instance
