Properties of an EBS Volume.

Example

declare const instance: ec2.Instance;
declare const role: iam.Role;

const volume = new ec2.Volume(this, 'Volume', {
  availabilityZone: 'us-west-2a',
  size: Size.gibibytes(500),
  encrypted: true,
});

volume.grantAttachVolume(role, [instance]);

availabilityZone

Type: string

The Availability Zone in which to create the volume.

autoEnableIo?

Type: boolean (optional, default: false)

Indicates whether the volume is auto-enabled for I/O operations.

By default, Amazon EBS disables I/O to the volume from attached EC2 instances when it determines that a volume's data is potentially inconsistent. If the consistency of the volume is not a concern, and you prefer that the volume be made available immediately if it's impaired, you can configure the volume to automatically enable I/O.

enableMultiAttach?

Type: boolean (optional, default: false)

Indicates whether Amazon EBS Multi-Attach is enabled.

See {@link https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-volumes-multi.html#considerations|Considerations and limitations} for the constraints of multi-attach.

encrypted?

Type: boolean (optional, default: false)

Specifies whether the volume should be encrypted.

The effect of setting the encryption state to true depends on the volume origin (new or from a snapshot), starting encryption state, ownership, and whether encryption by default is enabled. For more information, see {@link https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html#encryption-by-default|Encryption by Default} in the Amazon Elastic Compute Cloud User Guide.

Encrypted Amazon EBS volumes must be attached to instances that support Amazon EBS encryption. For more information, see {@link https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html#EBSEncryption_supported_instances|Supported Instance Types.}

encryptionKey?

Type: IKey (optional, default: The default KMS key for the account, region, and EC2 service is used.)

The customer-managed encryption key that is used to encrypt the Volume.

The encrypted property must be true if this is provided.

Note: If using an {@link aws-kms.IKey} created from a {@link aws-kms.Key.fromKeyArn()} here, then the KMS key must have the following in its Key policy; otherwise, the Volume will fail to create.

 {
   "Effect": "Allow",
   "Principal": { "AWS": "<arn for your account-user> ex: arn:aws:iam::00000000000:root" },
   "Resource": "*",
   "Action": [
     "kms:DescribeKey",
     "kms:GenerateDataKeyWithoutPlainText",
   ],
   "Condition": {
     "StringEquals": {
       "kms:ViaService": "ec2.<Region>.amazonaws.com", (eg: ec2.us-east-1.amazonaws.com)
       "kms:CallerAccount": "0000000000" (your account ID)
     }
   }
 }

iops?

Type: number (optional, default: None -- Required for io1 and io2 volumes. The default for gp3 volumes is 3,000 IOPS if omitted.)

The number of I/O operations per second (IOPS) to provision for the volume.

The maximum ratio is 50 IOPS/GiB for PROVISIONED_IOPS_SSD, and 500 IOPS/GiB for both PROVISIONED_IOPS_SSD_IO2 and GENERAL_PURPOSE_SSD_GP3. See {@link https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-ebs-volume.html} for more information.

This parameter is valid only for PROVISIONED_IOPS_SSD, PROVISIONED_IOPS_SSD_IO2 and GENERAL_PURPOSE_SSD_GP3 volumes.

removalPolicy?

Type: RemovalPolicy (optional, default: RemovalPolicy.RETAIN)

Policy to apply when the volume is removed from the stack.

size?

Type: Size (optional, default: If you're creating the volume from a snapshot and don't specify a volume size, the default is the snapshot size.)

The size of the volume, in GiBs.

You must specify either a snapshot ID or a volume size. See {@link https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-ec2-ebs-volume.html} for details on the allowable size for each type of volume.

snapshotId?

Type: string (optional, default: The EBS volume is not created from a snapshot.)

The snapshot from which to create the volume.

You must specify either a snapshot ID or a volume size.

volumeName?

Type: string (optional, default: The physical name will be allocated by CloudFormation at deployment time)

The value of the physicalName property of this resource.

volumeType?

Type: EbsDeviceVolumeType (optional, default: {@link EbsDeviceVolumeType.GENERAL_PURPOSE_SSD})

The type of the volume;

what type of storage to use to form the EBS Volume.
