Method Detail

virtualName

public final String virtualName()

The name of the instance store volume (virtual device) to attach to an instance at launch. The name must be in the form ephemeralX where X is a number starting from zero (0), for example, ephemeral0.

Returns:

The name of the instance store volume (virtual device) to attach to an instance at launch. The name must be in the form ephemeralX where X is a number starting from zero (0), for example, ephemeral0.

deviceName

public final String deviceName()

The device name assigned to the volume (for example, /dev/sdh or xvdh). For more information, see Device naming on Linux instances in the Amazon EC2 User Guide for Linux Instances.

To define a block device mapping, set the device name and exactly one of the following properties: Ebs, NoDevice, or VirtualName.

Returns:

The device name assigned to the volume (for example, /dev/sdh or xvdh). For more information, see Device naming on Linux instances in the Amazon EC2 User Guide for Linux Instances.

To define a block device mapping, set the device name and exactly one of the following properties: Ebs, NoDevice, or VirtualName.

ebs

public final Ebs ebs()

Information to attach an EBS volume to an instance at launch.

Returns:

Information to attach an EBS volume to an instance at launch.

noDevice

public final Boolean noDevice()

Setting this value to true prevents a volume that is included in the block device mapping of the AMI from being mapped to the specified device name at launch.

If NoDevice is true for the root device, instances might fail the EC2 health check. In that case, Amazon EC2 Auto Scaling launches replacement instances.

Returns:

Setting this value to true prevents a volume that is included in the block device mapping of the AMI from being mapped to the specified device name at launch.

If NoDevice is true for the root device, instances might fail the EC2 health check. In that case, Amazon EC2 Auto Scaling launches replacement instances.
