AWSAutoScalingEbs

Objective-C

@interface AWSAutoScalingEbs

Swift

class AWSAutoScalingEbs

Describes information used to set up an Amazon EBS volume specified in a block device mapping.

  • Indicates whether the volume is deleted on instance termination. For Amazon EC2 Auto Scaling, the default value is true.

    Declaration

    Objective-C

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

    Swift

    var deleteOnTermination: NSNumber? { get set }
  • Specifies whether the volume should be encrypted. Encrypted EBS volumes can only be attached to instances that support Amazon EBS encryption. For more information, see Supported Instance Types. If your AMI uses encrypted volumes, you can also only launch it on supported instance types.

    If you are creating a volume from a snapshot, you cannot specify an encryption value. Volumes that are created from encrypted snapshots are automatically encrypted, and volumes that are created from unencrypted snapshots are automatically unencrypted. By default, encrypted snapshots use the AWS managed CMK that is used for EBS encryption, but you can specify a custom CMK when you create the snapshot. The ability to encrypt a snapshot during copying also allows you to apply a new CMK to an already-encrypted snapshot. Volumes restored from the resulting copy are only accessible using the new CMK.

    Enabling encryption by default results in all EBS volumes being encrypted with the AWS managed CMK or a customer managed CMK, whether or not the snapshot was encrypted.

    For more information, see Using Encryption with EBS-Backed AMIs in the Amazon EC2 User Guide for Linux Instances and Required CMK Key Policy for Use with Encrypted Volumes in the Amazon EC2 Auto Scaling User Guide.

    Declaration

    Objective-C

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

    Swift

    var encrypted: NSNumber? { get set }
  • The number of I/O operations per second (IOPS) to provision for the volume. The maximum ratio of IOPS to volume size (in GiB) is 50:1. For more information, see Amazon EBS Volume Types in the Amazon EC2 User Guide for Linux Instances.

    Required when the volume type is io1. (Not used with standard, gp2, st1, or sc1 volumes.)

    Declaration

    Objective-C

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

    Swift

    var iops: NSNumber? { get set }
  • The snapshot ID of the volume to use.

    You must specify either a VolumeSize or a SnapshotId.

    Declaration

    Objective-C

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

    Swift

    var snapshotId: String? { get set }
  • The volume size, in Gibibytes (GiB).

    This can be a number from 1-1,024 for standard, 4-16,384 for io1, 1-16,384 for gp2, and 500-16,384 for st1 and sc1. If you specify a snapshot, the volume size must be equal to or larger than the snapshot size.

    Default: If you create a volume from a snapshot and you don’t specify a volume size, the default is the snapshot size.

    You must specify either a VolumeSize or a SnapshotId. If you specify both SnapshotId and VolumeSize, the volume size must be equal or greater than the size of the snapshot.

    Declaration

    Objective-C

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

    Swift

    var volumeSize: NSNumber? { get set }
  • The volume type, which can be standard for Magnetic, io1 for Provisioned IOPS SSD, gp2 for General Purpose SSD, st1 for Throughput Optimized HDD, or sc1 for Cold HDD. For more information, see Amazon EBS Volume Types in the Amazon EC2 User Guide for Linux Instances.

    Valid Values: standard | io1 | gp2 | st1 | sc1

    Declaration

    Objective-C

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

    Swift

    var volumeType: String? { get set }
