Amazon EC2 LaunchTemplate Ebs

The Ebs property type specifies parameters for a block device for an EBS volume in a Amazon EC2 launch template.

Ebs is a property of the Amazon EC2 LaunchTemplate BlockDeviceMapping property type.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "SnapshotId" : String,
  "VolumeType" : String,
  "KmsKeyId" : String,
  "Encrypted" : Boolean,
  "Iops" : Integer,
  "VolumeSize" : Integer,
  "DeleteOnTermination" : Boolean
}

YAML


SnapshotId: String
VolumeType: String
KmsKeyId: String
Encrypted: Boolean
Iops: Integer
VolumeSize: Integer
DeleteOnTermination: Boolean

Properties

DeleteOnTermination

Indicates whether the EBS volume is deleted on instance termination.

Required: No

Type: Boolean

Update requires: No interruption

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.

Required: No

Type: Boolean

Update requires: No interruption

Iops

The number of I/O operations per second (IOPS) that the volume supports. For io1, this represents the number of IOPS that are provisioned for the volume. For gp2, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting. For more information about General Purpose SSD baseline performance, I/O credits, and bursting, see Amazon EBS Volume Types in the Amazon EC2 User Guide for Linux Instances.

Condition: This parameter is required for requests to create io1 volumes; it is not used in requests to create gp2, st1, sc1, or standard volumes.

Required: No

Type: Integer

Update requires: No interruption

KmsKeyId

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

Required: No

Type: String

Update requires: No interruption

SnapshotId

The ID of the snapshot.

Required: No

Type: String

Update requires: No interruption

VolumeSize

The size of the volume, in GiB.

Default: If you're creating the volume from a snapshot and don't specify a volume size, the default is the snapshot size.

Required: No

Type: Integer

Update requires: No interruption

VolumeType

The volume type.

Valid values include: standard, io1, gp2, sc1, and st1.

Required: No

Type: String

Update requires: No interruption
