@Stability(Stable) public static interface CfnLaunchConfiguration.BlockDeviceMappingProperty extends
BlockDeviceMapping specifies a block device mapping for the BlockDeviceMappings property of the AWS::AutoScaling::LaunchConfiguration resource.

Each instance that is launched has an associated root device volume, either an Amazon EBS volume or an instance store volume. You can use block device mappings to specify additional EBS volumes or instance store volumes to attach to an instance when it is launched.

For more information, see Example block device mapping in the Amazon EC2 User Guide for Linux Instances .

 // The values are placeholders you should change.

  • Method Details

    • getDeviceName

      @Stability(Stable) @NotNull String getDeviceName()
      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 .

    • getEbs

      @Stability(Stable) @Nullable default Object getEbs()
      Information to attach an EBS volume to an instance at launch.
    • getNoDevice

      @Stability(Stable) @Nullable default Object getNoDevice()
      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.

    • getVirtualName

      @Stability(Stable) @Nullable default String getVirtualName()
      The name of the instance store volume (virtual device) to attach to an instance at launch.

      The name must be in the form ephemeral X where X is a number starting from zero (0), for example, ephemeral0 .

    • builder

      @Stability(Stable) static CfnLaunchConfiguration.BlockDeviceMappingProperty.Builder builder()
      a CfnLaunchConfiguration.BlockDeviceMappingProperty.Builder of CfnLaunchConfiguration.BlockDeviceMappingProperty
