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

       This object is used to describe the parameters used to create an Amazon EBS volume when running an image.
       Generally you will not call this directly, as all its methods are passed through by the
       VM::EC2::BlockDevice object returned from the blockDeviceMapping() call.

       See VM::EC2::BlockDevice for a simpler way to get the information needed.

       It is easy to confuse this with VM::EC2::BlockDevice::Mapping::EBS, which describes the attachment of an
       existing EBS volume to an instance. This class is instead used to store the parameters that will be used
       to generate a new EBS volume when an image is launched.

       The following object methods are supported:

        snapshotId  -- ID of the snapshot used to create this EBS when an
                       instance is launched from this image.
        volumeSize  -- Size of the EBS volume (in gigs).
        deleteOnTermination -- Whether this EBS will be deleted when the
                       instance terminates. Note that this will return
                       perl 0/1 values rather than the strings "false"/"true"
        volumeType  -- The volume type, one of "standard" or "io1"
        iops        -- The number of I/O operations per second that the volume
                       supports, an integer between 100 and 2000. Only valid for
                       volumes of type "io1".
