public SpotProvisioningSpecificationProperty()
Properties
AllocationStrategy
Specifies one of the following strategies to launch Spot Instance fleets: price-capacity-optimized
, capacity-optimized
, lowest-price
, or diversified
.
public string AllocationStrategy { get; set; }
Property Value
System.String
Remarks
For more information on the provisioning strategies, see Allocation strategies for Spot Instances in the Amazon EC2 User Guide for Linux Instances .
When you launch a Spot Instance fleet with the old console, it automatically launches with the capacity-optimized
strategy. You can't change the allocation strategy from the old console.
BlockDurationMinutes
The defined duration for Spot Instances (also known as Spot blocks) in minutes.
public Nullable<double> BlockDurationMinutes { get; set; }
Property Value
System.Nullable<System.Double>
Remarks
When specified, the Spot Instance does not terminate before the defined duration expires, and defined duration pricing for Spot Instances applies. Valid values are 60, 120, 180, 240, 300, or 360. The duration period starts as soon as a Spot Instance receives its instance ID. At the end of the duration, Amazon EC2 marks the Spot Instance for termination and provides a Spot Instance termination notice, which gives the instance a two-minute warning before it terminates.
Spot Instances with a defined duration (also known as Spot blocks) are no longer available to new customers from July 1, 2021. For customers who have previously used the feature, we will continue to support Spot Instances with a defined duration until December 31, 2022.
TimeoutAction
The action to take when TargetSpotCapacity
has not been fulfilled when the TimeoutDurationMinutes
has expired;
public string TimeoutAction { get; set; }
Property Value
System.String
Remarks
that is, when all Spot Instances could not be provisioned within the Spot provisioning timeout. Valid values are TERMINATE_CLUSTER
and SWITCH_TO_ON_DEMAND
. SWITCH_TO_ON_DEMAND specifies that if no Spot Instances are available, On-Demand Instances should be provisioned to fulfill any remaining Spot capacity.
TimeoutDurationMinutes
The Spot provisioning timeout period in minutes.
public double TimeoutDurationMinutes { get; set; }
Property Value
System.Double
Remarks
If Spot Instances are not provisioned within this time period, the TimeOutAction
is taken. Minimum value is 5 and maximum value is 1440. The timeout applies only during initial provisioning, when the cluster is first created.
