DeleteOnTermination => Bool

Indicates whether the EBS volume is deleted on instance termination. For more information, see Preserving Amazon EBS volumes on instance termination (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/terminating-instances.html#preserving-volumes-on-termination) in the Amazon EC2 User Guide.

Encrypted => Bool

Indicates whether the encryption state of an EBS volume is changed while being restored from a backing snapshot. 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 Amazon EBS encryption (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html#encryption-parameters) in the Amazon EC2 User Guide.

In no case can you remove encryption from an encrypted volume.

Encrypted volumes can only be attached to instances that support Amazon EBS encryption. For more information, see Supported instance types (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSEncryption.html#EBSEncryption_supported_instances).

This parameter is not returned by .

Iops => Int

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": 100-64,000 IOPS

For "io1" and "io2" volumes, we guarantee 64,000 IOPS only for Instances built on the Nitro System (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html#ec2-nitro-instances). Other instance families guarantee performance up to 32,000 IOPS.

This parameter is required for "io1" and "io2" volumes. The default for "gp3" volumes is 3,000 IOPS. This parameter is not supported for "gp2", "st1", "sc1", or "standard" volumes.

KmsKeyId => Str

Identifier (key ID, key alias, ID ARN, or alias ARN) for a customer managed CMK under which the EBS volume is encrypted.

This parameter is only supported on "BlockDeviceMapping" objects called by RunInstances (https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_RunInstances.html), RequestSpotFleet (https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_RequestSpotFleet.html), and RequestSpotInstances (https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_RequestSpotInstances.html).

OutpostArn => Str

The ARN of the Outpost on which the snapshot is stored.

SnapshotId => Str

The ID of the snapshot.

Throughput => Int

The throughput that the volume supports, in MiB/s.

This parameter is valid only for "gp3" volumes.

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

VolumeSize => Int

The size of the volume, in GiBs. You must specify either a snapshot ID or a volume size. If you specify a snapshot, the default is the snapshot size. You can specify a volume size that is equal to or larger than the snapshot size.

The following are the supported volumes sizes for each volume type:

• "gp2" and "gp3":1-16,384
• "io1" and "io2": 4-16,384
• "st1" and "sc1": 125-16,384
• "standard": 1-1,024

VolumeType => Str

The volume type. For more information, see Amazon EBS volume types (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSVolumeTypes.html) in the Amazon EC2 User Guide. If the volume type is "io1" or "io2", you must specify the IOPS that the volume supports.
