perl v5.38.2                                       2024-08-10             VM::EC2::BlockD...e::Mapping::EBS(3pm)

       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:

   $vol=$ebs->volume
       This returns the VM::EC2::Volume object that corresponds to this EBS. The volume will provide additional
       information, such as availabilit zone.
