# aws_autoscaling_launch_configuration{% #aws_autoscaling_launch_configuration %}

## `account_id`{% #account_id %}

**Type**: `STRING`

## `associate_public_ip_address`{% #associate_public_ip_address %}

**Type**: `BOOLEAN`**Provider name**: `AssociatePublicIpAddress`**Description**: Specifies whether to assign a public IPv4 address to the group's instances. If the instance is launched into a default subnet, the default is to assign a public IPv4 address, unless you disabled the option to assign a public IPv4 address on the subnet. If the instance is launched into a nondefault subnet, the default is not to assign a public IPv4 address, unless you enabled the option to assign a public IPv4 address on the subnet. For more information, see [Provide network connectivity for your Auto Scaling instances using Amazon VPC](https://docs.aws.amazon.com/autoscaling/ec2/userguide/asg-in-vpc.html) in the Amazon EC2 Auto Scaling User Guide.

## `block_device_mappings`{% #block_device_mappings %}

**Type**: `UNORDERED_LIST_STRUCT`**Provider name**: `BlockDeviceMappings`**Description**: The block device mapping entries that define the block devices to attach to the instances at launch. By default, the block devices specified in the block device mapping for the AMI are used. For more information, see [Block device mappings](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/block-device-mapping-concepts.html) in the Amazon EC2 User Guide for Linux Instances.

- `device_name`**Type**: `STRING`**Provider name**: `DeviceName`**Description**: The device name assigned to the volume (for example, `/dev/sdh` or `xvdh`). For more information, see [Device naming on Linux instances](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/device_naming.html) in the Amazon EC2 User Guide for Linux Instances.To define a block device mapping, set the device name and exactly one of the following properties: `Ebs`, `NoDevice`, or `VirtualName`.
- `ebs`**Type**: `STRUCT`**Provider name**: `Ebs`**Description**: Information to attach an EBS volume to an instance at launch.
  - `delete_on_termination`**Type**: `BOOLEAN`**Provider name**: `DeleteOnTermination`**Description**: Indicates whether the volume is deleted on instance termination. For Amazon EC2 Auto Scaling, the default value is `true`.
  - `encrypted`**Type**: `BOOLEAN`**Provider name**: `Encrypted`**Description**: Specifies whether the volume should be encrypted. Encrypted EBS volumes can only be attached to instances that support Amazon EBS encryption. For more information, see [Requirements for Amazon EBS encryption](https://docs.aws.amazon.com/ebs/latest/userguide/ebs-encryption-requirements.html) in the Amazon EBS User Guide. If your AMI uses encrypted volumes, you can also only launch it on supported instance types.If you are creating a volume from a snapshot, you cannot create an unencrypted volume from an encrypted snapshot. Also, you cannot specify a KMS key ID when using a launch configuration. If you enable encryption by default, the EBS volumes that you create are always encrypted, either using the Amazon Web Services managed KMS key or a customer-managed KMS key, regardless of whether the snapshot was encrypted. For more information, see [Use Amazon Web Services KMS keys to encrypt Amazon EBS volumes](https://docs.aws.amazon.com/autoscaling/ec2/userguide/ec2-auto-scaling-data-protection.html#encryption) in the Amazon EC2 Auto Scaling User Guide.
  - `iops`**Type**: `INT32`**Provider name**: `Iops`**Description**: The number of input/output (I/O) operations per second (IOPS) to provision for the volume. For `gp3` and `io1` 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
For `io1` volumes, we guarantee 64,000 IOPS only for [Instances built on the Amazon Web Services Nitro System](https://docs.aws.amazon.com/ec2/latest/instancetypes/ec2-nitro-instances.html). Other instance families guarantee performance up to 32,000 IOPS. `Iops` is supported when the volume type is `gp3` or `io1` and required only when the volume type is `io1`. (Not used with `standard`, `gp2`, `st1`, or `sc1` volumes.)
  - `snapshot_id`**Type**: `STRING`**Provider name**: `SnapshotId`**Description**: The snapshot ID of the volume to use. You must specify either a `VolumeSize` or a `SnapshotId`.
  - `throughput`**Type**: `INT32`**Provider name**: `Throughput`**Description**: The throughput (MiBps) to provision for a `gp3` volume.
  - `volume_size`**Type**: `INT32`**Provider name**: `VolumeSize`**Description**: The volume size, in GiBs. The following are the supported volumes sizes for each volume type:
    - `gp2` and `gp3`: 1-16,384
    - `io1`: 4-16,384
    - `st1` and `sc1`: 125-16,384
    - `standard`: 1-1,024
You must specify either a `SnapshotId` or a `VolumeSize`. If you specify both `SnapshotId` and `VolumeSize`, the volume size must be equal or greater than the size of the snapshot.
  - `volume_type`**Type**: `STRING`**Provider name**: `VolumeType`**Description**: The volume type. For more information, see [Amazon EBS volume types](https://docs.aws.amazon.com/ebs/latest/userguide/ebs-volume-types.html) in the Amazon EBS User Guide. Valid values: `standard` | `io1` | `gp2` | `st1` | `sc1` | `gp3`
- `no_device`**Type**: `BOOLEAN`**Provider name**: `NoDevice`**Description**: Setting this value to `true` prevents a volume that is included in the block device mapping of the AMI from being mapped to the specified device name at launch. If `NoDevice` is `true` for the root device, instances might fail the EC2 health check. In that case, Amazon EC2 Auto Scaling launches replacement instances.
- `virtual_name`**Type**: `STRING`**Provider name**: `VirtualName`**Description**: The name of the instance store volume (virtual device) to attach to an instance at launch. The name must be in the form ephemeralX where X is a number starting from zero (0), for example, `ephemeral0`.

- `http_tokens`**Type**: `STRING`**Provider name**: `HttpTokens`**Description**: The state of token usage for your instance metadata requests. If the parameter is not specified in the request, the default state is `optional`. If the state is `optional`, you can choose to retrieve instance metadata with or without a signed token header on your request. If you retrieve the IAM role credentials without a token, the version 1.0 role credentials are returned. If you retrieve the IAM role credentials using a valid signed token, the version 2.0 role credentials are returned. If the state is `required`, you must send a signed token header with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns the version 2.0 credentials; the version 1.0 credentials are not available.
