Instance Attribute Details

#delete_on_termination ⇒ Boolean

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*.

Returns:

#encrypted ⇒ Boolean

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.

end

#iops ⇒ Integer

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.

#kms_key_id ⇒ String

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], [RequestSpotFleet], and [RequestSpotInstances].
