VM::EC2::BlockDevice::Mapping::EBS - Object describing an EBS volume that has
been mapped onto an Amazon EC2 instance
use VM::EC2;
my $instance = $ec2->describe_instances(-instance_id=>'i-123456');
my @devices = $instance->blockDeviceMapping;
for my $d (@devices) {
my $ebs = $d->ebs;
$volume_id = $ebs->volumeId;
$status = $ebs->status;
$atime = $ebs->attachmentTime;
$delete = $ebs->delete;
$volume = $ebs->volume;
}
This object is used to describe an Amazon EBS volume that is mapped onto an EC2
block device. It is returned by VM::EC2->
describe_instances().
It is easy to confuse this with VM::EC2::BlockDevice::EBS, which describes the
parameters needed to create the EBS volume when an image is launched. This
class is instead used to describe an active mapping between an instance's
block device and the underlying EBS volume.
Because all the methods in this class are passed through to
VM::EC2::BlockDeviceMapping, it is somewhat simpler to call them directly on
the BlockDeviceMapping object:
my $instance = $ec2->describe_instances(-instance_id=>'i-123456');
my @devices = $instance->blockDeviceMapping;
for my $d (@devices) {
$volume_id = $d->volumeId;
$status = $d->status;
$atime = $d->attachmentTime;
$delete = $d->delete;
$volume = $d->volume;
}
The following object methods are supported:
volumeId -- ID of the volume.
status -- One of "attaching", "attached", "detaching", "detached"
attachTime -- Time this volume was attached
deleteOnTermination -- Whether the volume will be deleted when its attached
instance is deleted. Note that this returns the perl
0/1 booleans rather than "false"/"true" strings.
In addition, the following convenience method is supported:
This returns the VM::EC2::Volume object that corresponds to this EBS. The volume
will provide additional information, such as availabilit zone.
