  • :instance_id (String)

    The ID of the instance used to create a launch configuration for the group. Alternatively, specify a launch configuration instead of an EC2 instance.

    When you specify an ID of an instance, Auto Scaling creates a new launch configuration and associates it with the group. This launch configuration derives its attributes from the specified instance, with the exception of the block device mapping.

    For more information, see Create an Auto Scaling Group Using an EC2 Instance in the Auto Scaling User Guide.

  • :min_size (required, Integer)

    The minimum size of the group.

  • :max_size (required, Integer)

    The maximum size of the group.

  • :desired_capacity (Integer)

    The number of EC2 instances that should be running in the group. This number must be greater than or equal to the minimum size of the group and less than or equal to the maximum size of the group.

    One or more Availability Zones for the group. This parameter is optional if you specify one or more subnets.

  • :load_balancer_names (Array<String>)

    One or more Classic Load Balancers. To specify an Application Load Balancer, use TargetGroupARNs instead.

    For more information, see Using a Load Balancer With an Auto Scaling Group in the Auto Scaling User Guide.

    The Amazon Resource Names (ARN) of the target groups.

  • :health_check_type (String)

    The service to use for the health checks. The valid values are EC2 and ELB.

  • :health_check_grace_period (Integer)

    The amount of time, in seconds, that Auto Scaling waits before checking the health status of an EC2 instance that has come into service. During this time, any health check failures for the instance are ignored. The default is 0.

    This parameter is required if you are adding an ELB health check.

    For more information, see Health Checks in the Auto Scaling User Guide.

  • :placement_group (String)

    The name of the placement group into which you'll launch your instances, if any. For more information, see Placement Groups in the Amazon Elastic Compute Cloud User Guide.

  • :vpc_zone_identifier (String)

    A comma-separated list of subnet identifiers for your virtual private cloud (VPC).

    If you specify subnets and Availability Zones with this call, ensure that the subnets' Availability Zones match the Availability Zones specified.

    For more information, see Launching Auto Scaling Instances in a VPC in the Auto Scaling User Guide.

  • :termination_policies (Array<String>)

    One or more termination policies used to select the instance to terminate. These policies are executed in the order that they are listed.

    Indicates whether newly launched instances are protected from termination by Auto Scaling when scaling in.

  • :tags (Array<Types::Tag>)

    One or more tags.

    For more information, see Tagging Auto Scaling Groups and Instances in the Auto Scaling User Guide.

Options Hash (options):

  • :launch_configuration_name (required, String)

    The name of the launch configuration. This name must be unique within the scope of your AWS account.

    The ID of the Amazon Machine Image (AMI) to use to launch your EC2 instances. For more information, see Finding an AMI in the Amazon Elastic Compute Cloud User Guide.

  • :key_name (String)

    The name of the key pair. For more information, see Amazon EC2 Key Pairs in the Amazon Elastic Compute Cloud User Guide.

  • :security_groups (Array<String>)

    One or more security groups with which to associate the instances.

    If your instances are launched in EC2-Classic, you can either specify security group names or the security group IDs. For more information about security groups for EC2-Classic, see Amazon EC2 Security Groups in the Amazon Elastic Compute Cloud User Guide.

    If your instances are launched into a VPC, specify security group IDs. For more information, see Security Groups for Your VPC in the Amazon Virtual Private Cloud User Guide.

  • :classic_link_vpc_id (String)

    The ID of a ClassicLink-enabled VPC to link your EC2-Classic instances to. This parameter is supported only if you are launching EC2-Classic instances. For more information, see ClassicLink in the Amazon Elastic Compute Cloud User Guide.

  • :classic_link_vpc_security_groups (Array<String>)

    The IDs of one or more security groups for the specified ClassicLink-enabled VPC. This parameter is required if you specify a ClassicLink-enabled VPC, and is not supported otherwise. For more information, see ClassicLink in the Amazon Elastic Compute Cloud User Guide.

  • :user_data (String)

    The user data to make available to the launched EC2 instances. For more information, see Instance Metadata and User Data in the Amazon Elastic Compute Cloud User Guide.

  • :instance_id (String)

    The ID of the instance to use to create the launch configuration.

    The new launch configuration derives attributes from the instance, with the exception of the block device mapping.

    To create a launch configuration with a block device mapping or override any other instance attributes, specify them as part of the same request.

    For more information, see Create a Launch Configuration Using an EC2 Instance in the Auto Scaling User Guide.

  • :instance_monitoring (Types::InstanceMonitoring)

    Enables detailed monitoring (true) or basic monitoring (false) for the Auto Scaling instances.

  • :spot_price (String)

    The maximum hourly price to be paid for any Spot Instance launched to fulfill the request. Spot Instances are launched when the price you specify exceeds the current Spot market price. For more information, see Launching Spot Instances in Your Auto Scaling Group in the Auto Scaling User Guide.

  • :iam_instance_profile (String)

    The name or the Amazon Resource Name (ARN) of the instance profile associated with the IAM role for the instance.

    EC2 instances launched with an IAM role will automatically have AWS security credentials available. You can use IAM roles with Auto Scaling to automatically enable applications running on your EC2 instances to securely access other AWS resources. For more information, see Launch Auto Scaling Instances with an IAM Role in the Auto Scaling User Guide.

  • :ebs_optimized (Boolean)

    Indicates whether the instance is optimized for Amazon EBS I/O. By default, the instance is not optimized for EBS I/O. 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 usage charges apply. For more information, see Amazon EBS-Optimized Instances in the Amazon Elastic Compute Cloud User Guide.

  • :associate_public_ip_address (Boolean)

    Used for groups that launch instances into a virtual private cloud (VPC). Specifies whether to assign a public IP address to each instance. For more information, see Launching Auto Scaling Instances in a VPC in the Auto Scaling User Guide.

    If you specify this parameter, be sure to specify at least one subnet when you create your group.

    Default: If the instance is launched into a default subnet, the default is true. If the instance is launched into a nondefault subnet, the default is false. For more information, see Supported Platforms in the Amazon Elastic Compute Cloud User Guide.

  • :placement_tenancy (String)

    The tenancy of the instance. An instance with a tenancy of dedicated runs on single-tenant hardware and can only be launched into a VPC.

    You must set the value of this parameter to dedicated if want to launch Dedicated Instances into a shared tenancy VPC (VPC with instance placement tenancy attribute set to default).

    If you specify this parameter, be sure to specify at least one subnet when you create your group.

    For more information, see Launching Auto Scaling Instances in a VPC in the Auto Scaling User Guide.
