SpotInstancePoolsToUseCount	Integer	No	No	The number of instances that the auto provisioning group creates by selecting the instance type of the lowest price.	The value of this property must be smaller than the relevant number that you specify in the configurations of the launch template. This property only takes effect when the SpotAllocationStrategy property is set to lowest-price.
AutoProvisioningGroupName	String	No	No	The name of the auto provisioning group.	The name must be 2 to 128 characters in length, and can contain letters, digits, colons(:), underscores (_), and hyphens (-). The name must start with a letter but cannot start with `http://` or `https://`.
ValidUntil	String	No	No	The point in time at which the auto provisioning group expires. The auto provisioning group is valid during the period of time between the point in time that is specified by the ValidFrom property and this point in time.	Specify the time in the ISO 8601 standard in the `yyyy-MM-ddTHH:mm:ssZ` format. The time must be in UTC.
Description	String	No	No	The description of the auto provisioning group.	None.
PayAsYouGoAllocationStrategy	String	No	No	The policy based on which the auto provisioning group creates pay-as-you-go instances.	Default value: lowest-price. Valid values: lowest-price: the cost optimization policy. The auto provisioning group selects the instance type of the lowest price to create pay-as-you-go instances. prioritized: the priority-based policy. The auto provisioning group creates pay-as-you-go instances based on the priority that is specified by the LaunchTemplateConfig property.
MaxSpotPrice	Number	No	Yes	The highest price of preemptible instances in the auto provisioning group.	If you specify the MaxPrice property in LaunchTemplateConfig and the MaxSpotPrice property, the smaller value between the values of both properties is used as the highest price.

You can call the DescribeLaunchTemplates operation to query available launch templates. When you specify the LaunchTemplateId and LaunchConfiguration properties, the value of the LaunchTemplateId property takes precedence.
DefaultTargetCapacityType	String	No	Yes	The type of supplemental instances. When the sum of the values of PayAsYouGoTargetCapacity and SpotTargetCapacity properties is smaller than the value of the TotalTargetCapacity property, the auto provisioning group creates instances of the specified billing method to meet the capacity requirements.	Default value: Spot. Valid values: PayAsYouGo: pay-as-you-go instances Spot: preemptible instances
SpotInstanceInterruptionBehavior	String	No	No	The next operation that the system performs after the excess preemptible instances are stopped.	Default value: stop. Valid values: stop: retains the excess preemptible instances in the stopped state. terminate: releases the excess preemptible instances.

When the auto provisioning group is started, the system delivers clusters until the target capacity is reached. The system also monitors the capacity in real time. If the target capacity of the auto provisioning group is not reached, the system continues creating ECS instances until the target capacity is reached.
LaunchTemplateVersion	String	No	No	The version of the launch template that is associated with the auto provisioning group.	You can call the DescribeLaunchTemplateVersions operation to query available versions of the launch template.
