VM::EC2::BlockDevice::Attachment - Object describing the attachment of an EBS volume to an instance
use VM::EC2; $ec2 = VM::EC2->new(...); $volume = $ec2->describe_volumes(-volume_id=>'vol-12345'); $attachment = $ec2->attachment; $volId = $attachment->volumeId; $device = $attachment->device; $instanceId = $attachment->instanceId; $status = $attachment->status; $time = $attachment->attachTime; $delete = $attachment->deleteOnTermination; $attachment->deleteOnTermination(1); # change delete flag
This object is used to describe the attachment of an Amazon EBS volume to an instance. It is returned by VM::EC2::Volume->attachment().
The following object methods are supported:
volumeId -- ID of the volume. instanceId -- ID of the instance status -- Attachment state, one of "attaching", "attached", "detaching", "detached". attachTime -- Timestamp for when volume was attached deleteOnTermination -- True if the EBS volume will be deleted when its attached instance terminates. Note that this is a Perl true, and not the string "true".
The deleteOnTermination method is slightly more sophisticated than the result from the standard AWS API because it returns the CURRENT deleteOnTermination flag for the attachment, which might have been changed by VM::EC2->modify_instance_attributes(). You may also change the deleteOnTermination state by passing a boolean argument to the method:
In addition, this class provides several convenience functions:
Returns the VM::EC2::Instance corresponding to this attachment.
Returns the VM::EC2::Volume object corresponding to this attachment.
Alias for device() to be compatible with VM::EC2::BlockDevice::Mapping call.
Change the deleteOnTermination flag on this attachment.
Refreshes the information in the object and returns status().
Calls AWS to refresh the attachment information.
When used in a string context, this object will interpolate into a string of the format "volumeId=>instanceId".
