SpotOptionsRequest
Describes the configuration of Spot Instances in an EC2 Fleet request.
Contents
- AllocationStrategy
-
The strategy that determines how to allocate the target Spot Instance capacity across the Spot Instance pools specified by the EC2 Fleet.
lowest-price
- EC2 Fleet launches instances from the Spot Instance pools with the lowest price.diversified
- EC2 Fleet launches instances from all of the Spot Instance pools that you specify.capacity-optimized
(recommended) - EC2 Fleet launches instances from Spot Instance pools with optimal capacity for the number of instances that are launching. To give certain instance types a higher chance of launching first, usecapacity-optimized-prioritized
. Set a priority for each instance type by using thePriority
parameter forLaunchTemplateOverrides
. You can assign the same priority to differentLaunchTemplateOverrides
. EC2 implements the priorities on a best-effort basis, but optimizes for capacity first.capacity-optimized-prioritized
is supported only if your fleet uses a launch template. Note that if the On-DemandAllocationStrategy
is set toprioritized
, the same priority is applied when fulfilling On-Demand capacity.Default:
lowest-price
Type: String
Valid Values:
lowest-price | diversified | capacity-optimized | capacity-optimized-prioritized
Required: No
- InstanceInterruptionBehavior
-
The behavior when a Spot Instance is interrupted.
Default:
terminate
Type: String
Valid Values:
hibernate | stop | terminate
Required: No
- InstancePoolsToUseCount
-
The number of Spot pools across which to allocate your target Spot capacity. Supported only when Spot
AllocationStrategy
is set tolowest-price
. EC2 Fleet selects the cheapest Spot pools and evenly allocates your target Spot capacity across the number of Spot pools that you specify.Note that EC2 Fleet attempts to draw Spot Instances from the number of pools that you specify on a best effort basis. If a pool runs out of Spot capacity before fulfilling your target capacity, EC2 Fleet will continue to fulfill your request by drawing from the next cheapest pool. To ensure that your target capacity is met, you might receive Spot Instances from more than the number of pools that you specified. Similarly, if most of the pools have no Spot capacity, you might receive your full target capacity from fewer than the number of pools that you specified.
