Name	Type	Default	Description
Required · needed to use this module
name	string	—	Name used across the resources created
Optional
autoscaling_group_tags	map(string)	{}	A map of additional tags to add to the autoscaling group
autoscaling_group_tags_not_propagate_at_launch	list(string)	[]	A list of tag keys that should NOT be propagated to launched EC2 instances
availability_zone_distribution	object({...})	null	A map of configuration for capacity distribution across availability zones
availability_zones	list(string)	null	A list of Availability Zones where instances in the Auto Scaling group can be created. Used for launching into the default VPC subnet in each Availability Zone when not using the `vpc_zone_identifier` attribute, or for attaching a network interface when an existing network interface ID is specified in a launch template. Conflicts with `vpc_zone_identifier`
block_device_mappings	list({...})	null	Specify volumes to attach to the instance besides the volumes specified by the AMI
capacity_rebalance	bool	null	Indicates whether capacity rebalance is enabled
capacity_reservation_specification	object({...})	null	Targeting for EC2 capacity reservations
context	string	null	Reserved
cpu_options	object({...})	null	The CPU options for the instance
create	bool	true	Determines whether to create autoscaling group or not
create_iam_instance_profile	bool	false	Determines whether an IAM instance profile is created or to use an existing IAM instance profile
create_launch_template	bool	true	Determines whether to create launch template or not
credit_specification	object({...})	null	Customize the credit specification of the instance
default_cooldown	number	null	The amount of time, in seconds, after a scaling activity completes before another scaling activity can start
default_instance_warmup	number	null	Amount of time, in seconds, until a newly launched instance can contribute to the Amazon CloudWatch metrics. This delay lets an instance finish initializing before Amazon EC2 Auto Scaling aggregates instance metrics, resulting in more reliable usage data. Set this value equal to the amount of time that it takes for resource consumption to become stable after an instance reaches the InService state.
default_version	string	null	Default Version of the launch template
desired_capacity	number	null	The number of Amazon EC2 instances that should be running in the autoscaling group
desired_capacity_type	string	null	The unit of measurement for the value specified for desired_capacity. Supported for attribute-based instance type selection only. Valid values: `units`, `vcpu`, `memory-mib`.
disable_api_stop	bool	null	If true, enables EC2 instance stop protection
disable_api_termination	bool	null	If true, enables EC2 instance termination protection
ebs_optimized	bool	null	If true, the launched EC2 instance will be EBS-optimized

enabled_metrics	list(string)	[]	A list of metrics to collect. The allowed values are `GroupDesiredCapacity`, `GroupInServiceCapacity`, `GroupPendingCapacity`, `GroupMinSize`, `GroupMaxSize`, `GroupInServiceInstances`, `GroupPendingInstances`, `GroupStandbyInstances`, `GroupStandbyCapacity`, `GroupTerminatingCapacity`, `GroupTerminatingInstances`, `GroupTotalCapacity`, `GroupTotalInstances`
enclave_options	object({...})	null	Enable Nitro Enclaves on launched instances
force_delete	bool	null	Allows deleting the Auto Scaling Group without waiting for all instances in the pool to terminate. You can force an Auto Scaling Group to delete even if it's in the process of scaling a resource. Normally, Terraform drains all the instances before deleting the group. This bypasses that behavior and potentially leaves resources dangling
force_delete_warm_pool	bool	null	Allows deleting the Auto Scaling Group without waiting for all instances in the warm pool to terminate
health_check_grace_period	number	null	Time (in seconds) after instance comes into service before checking health
health_check_type	string	null	`EC2` or `ELB`. Controls how health checking is done
hibernation_options	object({...})	null	The hibernation options for the instance
iam_instance_profile_arn	string	null	Amazon Resource Name (ARN) of an existing IAM instance profile. Used when `create_iam_instance_profile` = `false`

iam_role_name	string	null	Name to use on IAM role created
iam_role_path	string	null	IAM role path

ignore_desired_capacity_changes	bool	false	Determines whether the `desired_capacity` value is ignored after initial apply. See README note for more details
ignore_failed_scaling_activities	bool	false	Whether to ignore failed Auto Scaling scaling activities while waiting for capacity. The default is false -- failed scaling activities cause errors to be returned.
image_id	string	null	The AMI from which to launch the instance
initial_lifecycle_hooks	list({...})	null	One or more Lifecycle Hooks to attach to the Auto Scaling Group before instances are launched. The syntax is exactly the same as the separate `aws_autoscaling_lifecycle_hook` resource, without the `autoscaling_group_name` attribute. Please note that this will only work when creating a new Auto Scaling Group. For all other use-cases, please use `aws_autoscaling_lifecycle_hook` resource
