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.

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.
SpotTargetCapacity String No Yes The target capacity of preemptible instances in the auto provisioning group. This value must be smaller than the value of the TotalTargetCapacity property.
SpotAllocationStrategy String No No The policy based on which the auto provisioning group creates preemptible instances. Default value: lowest-price. Valid values:

TotalTargetCapacity String Yes Yes The total target capacity of the auto provisioning group. The value must be a positive integer. The total target capacity of the auto provisioning group must be at least the sum of the values of the PayAsYouGoTargetCapacity and SpotTargetCapacity properties.
AutoProvisioningGroupType String No No The delivery type of the auto provisioning group. Default value: maintain. Valid values:
  • request: the one-time delivery. When the auto provisioning group is started, the system delivers clusters only once. If the clusters fail to be distributed, the system does not retry the delivery.
  • maintain: the continuous delivery. 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.
ValidFrom String No No The point in time at which the auto provisioning group is started.
