AWSAutoScalingBlockDeviceMapping

Objective-C

@interface AWSAutoScalingBlockDeviceMapping

Swift

class AWSAutoScalingBlockDeviceMapping

Describes a block device mapping.

Required parameters: [DeviceName]

  • The device name exposed to the EC2 instance (for example, /dev/sdh or xvdh). For more information, see Device Naming on Linux Instances in the Amazon EC2 User Guide for Linux Instances.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable deviceName;

    Swift

    var deviceName: String? { get set }
  • ebs

    Parameters used to automatically set up EBS volumes when an instance is launched.

    You can specify either VirtualName or Ebs, but not both.

    Declaration

    Objective-C

    @property (nonatomic, strong) AWSAutoScalingEbs *_Nullable ebs;

    Swift

    var ebs: AWSAutoScalingEbs? { get set }
  • Setting this value to true suppresses the specified device included in the block device mapping of the AMI.

    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.

    If you specify NoDevice, you cannot specify Ebs.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSNumber *_Nullable noDevice;

    Swift

    var noDevice: NSNumber? { get set }
  • The name of the virtual device (for example, ephemeral0).

    You can specify either VirtualName or Ebs, but not both.

    Declaration

    Objective-C

    @property (nonatomic, strong) NSString *_Nullable virtualName;

    Swift

    var virtualName: String? { get set }
