Description

Creates an Auto Scaling group with the specified name and attributes. If you exceed your maximum limit of Auto Scaling groups, the call fails. To query this limit, call the DescribeAccountLimits API. For information about updating this limit, see Amazon EC2 Auto Scaling Service Quotas in the Amazon EC2 Auto Scaling User Guide. For introductory exercises for creating an Auto Scaling group, see Getting Started with Amazon EC2 Auto Scaling and Tutorial: Set Up a Scaled and Load-Balanced Application in the Amazon EC2 Auto Scaling User Guide. For more information, see Auto Scaling Groups in the Amazon EC2 Auto Scaling User Guide. Every Auto Scaling group has three size parameters (DesiredCapacity, MaxSize, and MinSize). Usually, you set these sizes based on a specific number of instances. However, if you configure a mixed instances policy that defines weights for the instance types, you must specify these sizes with the same units that you use for weighting instances.

Parameters

-AutoScalingGroupName <String>
The name of the Auto Scaling group. This name must be unique per Region per account.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-AvailabilityZone <String[]>

Accept pipeline input?True (ByPropertyName)
AliasesAvailabilityZones
-DefaultCooldown <Int32>
The amount of time, in seconds, after a scaling activity completes before another scaling activity can start. The default value is 300.This setting applies when using simple scaling policies, but not when using other scaling policies or scheduled scaling. For more information, see Scaling Cooldowns for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-DesiredCapacity <Int32>
The desired capacity is the initial capacity of the Auto Scaling group at the time of its creation and the capacity it attempts to maintain. It can scale beyond this capacity if you configure automatic scaling.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. If you do not specify a desired capacity, the default is the minimum size of the group.
Required?False

This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-HealthCheckGracePeriod <Int32>
The amount of time, in seconds, that Amazon EC2 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 value is 0.For more information, see Health Check Grace Period in the Amazon EC2 Auto Scaling User Guide.Required if you are adding an ELB health check.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-HealthCheckType <String>
The service to use for the health checks. The valid values are EC2 and ELB. The default value is EC2.

Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-InstanceId <String>
The ID of the instance used to create a launch configuration for the group. To get the instance ID, use the Amazon EC2 DescribeInstances API operation.When you specify an ID of an instance, Amazon EC2 Auto Scaling creates a new launch configuration and associates it with the group. This launch configuration derives its attributes from the specified instance, except for the block device mapping.You must specify one of the following parameters in your request: LaunchConfigurationName, LaunchTemplate, InstanceId, or MixedInstancesPolicy.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

New launch template versions can be created using the Amazon EC2 CreateLaunchTemplateVersion API.If the value is $Latest, Amazon EC2 Auto Scaling selects the latest version of the launch template when launching instances. If the value is $Default, Amazon EC2 Auto Scaling selects the default version of the launch template when launching instances. The default value is $Default.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-LifecycleHookSpecificationList <LifecycleHookSpecification[]>
One or more lifecycle hooks.
Required?False
Position?Named
