Properties
associatePublicIpAddressboolean | IResolvableassociate_public_ip_addresstyping.Union[bool, IResolvable]associatePublicIpAddressBooleanAssociatePublicIpAddressboolAssociatePublicIpAddressinterface{}#notes
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.
If you specify true , each instance in the Auto Scaling group receives a unique public IPv4 address. For more information, see Provide network connectivity for your Auto Scaling instances using Amazon VPC in the Amazon EC2 Auto Scaling User Guide .
If you specify this property, you must specify at least one subnet for VPCZoneIdentifier when you create your group.

By default, the block devices specified in the block device mapping for the AMI are used. For more information, see Block device mappings in the Amazon EC2 User Guide .

The optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal I/O performance. This optimization is not available with all instance types. Additional fees are incurred when you enable EBS optimization for an instance type that is not EBS-optimized by default. For more information, see Amazon EBS-optimized instances in the Amazon EC2 User Guide .
The default value is false .
iamInstanceProfilestring | IInstanceProfileRefiam_instance_profiletyping.Union[str, IInstanceProfileRef]iamInstanceProfileStringIamInstanceProfilestringIamInstanceProfileinterface{}#notes
The instance profile contains the IAM role. For more information, see IAM role for applications that run on Amazon EC2 instances in the Amazon EC2 Auto Scaling User Guide .
For more information, see Find a Linux AMI in the Amazon EC2 User Guide .
If you specify InstanceId , an ImageId is not required.
notes
When you use an instance to create a launch configuration, all properties are derived from the instance with the exception of BlockDeviceMapping and AssociatePublicIpAddress . You can override any properties from the instance by specifying them in the launch configuration.
instanceMonitoringboolean | IResolvableinstance_monitoringtyping.Union[bool, IResolvable]instanceMonitoringBooleanInstanceMonitoringboolInstanceMonitoringinterface{}#notes
The default value is true (enabled).
When detailed monitoring is enabled, Amazon CloudWatch generates metrics every minute and your account is charged a fee. When you disable detailed monitoring, CloudWatch generates metrics every 5 minutes. For more information, see Configure monitoring for Auto Scaling instances in the Amazon EC2 Auto Scaling User Guide .
notes
For information about available instance types, see Available instance types in the Amazon EC2 User Guide .
If you specify InstanceId , an InstanceType is not required.
We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see User provided kernels in the Amazon EC2 User Guide .
For more information, see Amazon EC2 key pairs and Amazon EC2 instances in the Amazon EC2 User Guide .

An instance with dedicated tenancy runs on isolated, single-tenant hardware and can only be launched into a VPC. To launch dedicated instances into a shared tenancy VPC (a VPC with the instance placement tenancy attribute set to default ), you must set the value of this property to dedicated .
If you specify PlacementTenancy , you must specify at least one subnet for VPCZoneIdentifier when you create your group.
Valid values: default | dedicated
We recommend that you use PV-GRUB instead of kernels and RAM disks. For more information, see User provided kernels in the Amazon EC2 User Guide .
securityGroupsstring | ISecurityGroupRef[]security_groupstyping.List[typing.Union[str, ISecurityGroupRef]]securityGroupsList<String>SecurityGroupsstring[]SecurityGroups*[]interface{}#notes
The list can contain both the IDs of existing security groups and references to SecurityGroup resources created in the template.
For more information, see Control traffic to resources using security groups in the Amazon Virtual Private Cloud User Guide .
notes
Spot Instances are launched when the price you specify exceeds the current Spot price. For more information, see Request Spot Instances for fault-tolerant and flexible applications in the Amazon EC2 Auto Scaling User Guide .
Valid Range: Minimum value of 0.001
When you change your maximum price by creating a new launch configuration, running instances will continue to run as long as the maximum price for those running instances is higher than the current Spot price.
For more information, see Instance metadata and user data in the Amazon EC2 User Guide for Linux Instances .
