SpotProvisioningSpecification class
The launch specification for Spot Instances in the instance fleet, which determines the defined duration, provisioning timeout behavior, and allocation strategy.
Constructors

Properties
- allocationStrategy → SpotProvisioningAllocationStrategy?
-
Specifies the strategy to use in launching Spot Instance fleets. Currently,
the only option is capacity-optimized (the default), which launches
instances from Spot Instance pools with optimal capacity for the number of
instances that are launching.
final
- blockDurationMinutes → int?
-
The defined duration for Spot Instances (also known as Spot blocks) in
minutes. 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.

- hashCode → int
-
The hash code for this object.

A representation of the runtime type of the object.

- timeoutAction → SpotProvisioningTimeoutAction
-
The action to take when
TargetSpotCapacity
has not been fulfilled when theTimeoutDurationMinutes
has expired; that is, when all Spot Instances could not be provisioned within the Spot provisioning timeout. Valid values areTERMINATE_CLUSTER
andSWITCH_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.final - timeoutDurationMinutes → int
-
The spot provisioning timeout period in minutes. 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.final
