Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "AllocationStrategy" : String,
  "InstanceInterruptionBehavior" : String,
  "InstancePoolsToUseCount" : Integer,
  "MaxTotalPrice" : String,
  "MinTargetCapacity" : Integer,
  "SingleAvailabilityZone" : Boolean,
  "SingleInstanceType" : Boolean
}

Properties

AllocationStrategy

Indicates how to allocate the target Spot Instance capacity across the Spot Instance pools specified by the EC2 Fleet.

If the allocation strategy is lowestPrice, EC2 Fleet launches instances from the Spot Instance pools with the lowest price. This is the default allocation strategy.

If the allocation strategy is diversified, EC2 Fleet launches instances from all the Spot Instance pools that you specify.

If the allocation strategy is capacityOptimized, EC2 Fleet launches instances from Spot Instance pools that are optimally chosen based on the available Spot Instance capacity.

Allowed Values: lowestPrice | diversified | capacityOptimized

Required: No

Type: String

Update requires: Replacement

InstanceInterruptionBehavior

The behavior when a Spot Instance is interrupted. The default is terminate.

Required: No

Type: String

Allowed values: hibernate | stop | terminate

Update requires: Replacement

InstancePoolsToUseCount

The number of Spot pools across which to allocate your target Spot capacity. Valid only when Spot AllocationStrategy is set to lowest-price. EC2 Fleet selects the cheapest Spot pools and evenly allocates your target Spot capacity across the number of Spot pools that you specify.

Required: No

Type: Integer

Update requires: Replacement

MaxTotalPrice

The maximum amount per hour for Spot Instances that you're willing to pay.

Required: No

Type: String

Update requires: Replacement

MinTargetCapacity

The minimum target capacity for Spot Instances in the fleet. If the minimum target capacity is not reached, the fleet launches no instances.

Required: No

Type: Integer

Update requires: Replacement

SingleAvailabilityZone

Indicates that the fleet launches all Spot Instances into a single Availability Zone. Supported only for fleets of type instant.

Required: No

Type: Boolean

Update requires: Replacement

SingleInstanceType

Indicates that the fleet uses a single instance type to launch all Spot Instances in the fleet. Supported only for fleets of type instant.

Required: No

Type: Boolean

Update requires: Replacement
