Describes a block device for an EBS volume.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§delete_on_termination: Option<bool>

Indicates whether the EBS volume is deleted on instance termination. For more information, see Preserving Amazon EBS volumes on instance termination in the Amazon EC2 User Guide.

§iops: Option<i32>

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 required for io1 and io2 volumes. The default for gp3 volumes is 3,000 IOPS.

§snapshot_id: Option<String>

The ID of the snapshot.

§volume_size: Option<i32>

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 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

§volume_type: Option<VolumeType>

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

§kms_key_id: Option<String>

Identifier (key ID, key alias, key ARN, or alias ARN) of the customer managed KMS key to use for EBS encryption.

This parameter is only supported on BlockDeviceMapping objects called by RunInstances, RequestSpotFleet, and RequestSpotInstances.

§throughput: Option<i32>

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.

§outpost_arn: Option<String>

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

This parameter is not supported when using CreateImage.

§encrypted: Option<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 in the Amazon EBS 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.

This parameter is not returned by DescribeImageAttribute.

For CreateImage and RegisterImage, whether you can include this parameter, and the allowed values differ depending on the type of block device mapping you are creating.

  • If you are creating a block device mapping for a new (empty) volume, you can include this parameter, and specify either true for an encrypted volume, or false for an unencrypted volume. If you omit this parameter, it defaults to false (unencrypted).

  • If you are creating a block device mapping from an existing encrypted or unencrypted snapshot, you must omit this parameter. If you include this parameter, the request will fail, regardless of the value that you specify.

  • If you are creating a block device mapping from an existing unencrypted volume, you can include this parameter, but you must specify false. If you specify true, the request will fail. In this case, we recommend that you omit the parameter.

  • If you are creating a block device mapping from an existing encrypted volume, you can include this parameter, and specify either true or false. However, if you specify false, the parameter is ignored and the block device mapping is always encrypted. In this case, we recommend that you omit the parameter.

§volume_initialization_rate: Option<i32>

Specifies the Amazon EBS Provisioned Rate for Volume Initialization (volume initialization rate), in MiB/s, at which to download the snapshot blocks from Amazon S3 to the volume. This is also known as volume initialization. Specifying a volume initialization rate ensures that the volume is initialized at a predictable and consistent rate after creation.

This parameter is supported only for volumes created from snapshots. Omit this parameter if:

  • You want to create the volume using fast snapshot restore. You must specify a snapshot that is enabled for fast snapshot restore. In this case, the volume is fully initialized at creation.

    If you specify a snapshot that is enabled for fast snapshot restore and a volume initialization rate, the volume will be initialized at the specified rate instead of fast snapshot restore.

  • You want to create a volume that is initialized at the default rate.

For more information, see Initialize Amazon EBS volumes in the Amazon EC2 User Guide.

This parameter is not supported when using CreateImage.

Valid range: 100 - 300 MiB/s
