LaunchTemplateEbsBlockDeviceRequest

The parameters for a block device for an EBS volume.

Contents

DeleteOnTermination

Indicates whether the EBS volume is deleted on instance termination.

Type: Boolean

Required: No

Encrypted

Indicates whether the EBS volume is encrypted. Encrypted volumes can only be attached to instances that support Amazon EBS encryption. If you are creating a volume from a snapshot, you can't specify an encryption value.

Type: Boolean

Required: No

Iops

The number of I/O operations per second (IOPS). For gp3, io1, and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.

The following are the supported values for each volume type:

  • gp3: 3,000 - 16,000 IOPS

  • io1: 100 - 64,000 IOPS

  • io2: 100 - 256,000 IOPS

For io2 volumes, you can achieve up to 256,000 IOPS on instances built on the Nitro System. On other instances, you can achieve performance up to 32,000 IOPS.

This parameter is supported for io1, io2, and gp3 volumes only.

Type: Integer

Required: No

KmsKeyId

The ARN of the symmetric AWS Key Management Service (AWS KMS) CMK used for encryption.

Type: String

Required: No

SnapshotId

The ID of the snapshot.

Type: String

Required: No

Throughput

The throughput to provision for a gp3 volume, with a maximum of 1,000 MiB/s.

Valid Range: Minimum value of 125. Maximum value of 1000.

Type: Integer

Required: No

VolumeSize

The size of the volume, in GiBs. You must specify either a snapshot ID or a volume size. The following are the supported volumes sizes for each volume type:

  • gp2 and gp3: 1 - 16,384 GiB

  • io1: 4 - 16,384 GiB

  • io2: 4 - 65,536 GiB

  • st1 and sc1: 125 - 16,384 GiB

  • standard: 1 - 1024 GiB

Type: Integer

Required: No

VolumeType

The volume type. For more information, see Amazon EBS volume types in the Amazon EBS User Guide.

Type: String

Valid Values: standard | io1 | io2 | gp2 | sc1 | st1 | gp3

Required: No
