aws_launch_configuration

Provides a resource to create a new launch configuration, used for autoscaling groups.

Example Usage

resource "aws_launch_configuration" "as_conf" {
    name = "web_config"
    image_id = "ami-1234"
    instance_type = "m1.small"
}

Argument Reference

The following arguments are supported:

name - (Required) The name of the launch configuration.
image_id - (Required) The EC2 image ID to launch.
instance_type - (Required) The size of instance to launch.
iam_instance_profile - (Optional) The IAM instance profile to associate with launched instances.
key_name - (Optional) The key name that should be used for the instance.
security_groups - (Optional) A list of associated security group IDS.
associate_public_ip_address - (Optional) Associate a public ip address with an instance in a VPC.
user_data - (Optional) The user data to provide when launching the instance.
block_device_mapping - (Optional) A list of block devices to add. Their keys are documented below.

Block devices

Each of the *_block_device attributes controls a portion of the AWS Launch Configuration's "Block Device Mapping". It's a good idea to familiarize yourself with AWS's Block Device Mapping docs to understand the implications of using these attributes.

The root_block_device mapping supports the following:

volume_type - (Optional) The type of volume. Can be "standard", "gp2", or "io1". (Default: "standard").
volume_size - (Optional) The size of the volume in gigabytes.
iops - (Optional) The amount of provisioned IOPS. This must be set with a volume_type of "io1".
delete_on_termination - (Optional) Whether the volume should be destroyed on instance termination (Default: true).

Modifying any of the root_block_device settings requires resource replacement.

Each ebs_block_device supports the following:

device_name - The name of the device to mount.
snapshot_id - (Optional) The Snapshot ID to mount.
volume_type - (Optional) The type of volume. Can be "standard", "gp2", or "io1". (Default: "standard").
volume_size - (Optional) The size of the volume in gigabytes.
iops - (Optional) The amount of provisioned IOPS. This must be set with a volume_type of "io1".
delete_on_termination - (Optional) Whether the volume should be destroyed on instance termination (Default: true).

Modifying any ebs_block_device currently requires resource replacement.

Each ephemeral_block_device supports the following:

device_name - The name of the block device to mount on the instance.
virtual_name - The Instance Store Device Name (e.g. "ephemeral0")

Each AWS Instance type has a different set of Instance Store block devices available for attachment. AWS publishes a list of which ephemeral devices are available on each type. The devices are always identified by the virtual_name in the format "ephemeral{0..N}".

Attributes Reference

The following attributes are exported:

id - The ID of the launch configuration.
