  • Method Details

    • getAvailabilityZone

      @Stability(Stable) @Nullable default String getAvailabilityZone()
      The Availability Zone in which to launch the instances.

    • getInstanceRequirements

      @Stability(Stable) @Nullable default Object getInstanceRequirements()
      The instance requirements.

      When you specify instance requirements, Amazon EC2 will identify instance types with the provided requirements, and then use your On-Demand and Spot allocation strategies to launch instances from these instance types, in the same way as when you specify a list of instance types.

      If you specify InstanceRequirements , you can't specify InstanceType .

    • getInstanceType

      @Stability(Stable) @Nullable default String getInstanceType()
      The instance type.

    • getPriority

      @Stability(Stable) @Nullable default Number getPriority()
      The priority for the launch template override. The highest priority is launched first.

      If OnDemandAllocationStrategy is set to prioritized , Spot Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity.

      If the Spot AllocationStrategy is set to capacityOptimizedPrioritized , Spot Fleet uses priority on a best-effort basis to determine which launch template override to use in fulfilling Spot capacity, but optimizes for capacity first.

      Valid values are whole numbers starting at 0 . The lower the number, the higher the priority. If no number is set, the launch template override has the lowest priority. You can set the same priority for different launch template overrides.

    • getSpotPrice

      @Stability(Stable) @Nullable default String getSpotPrice()
      The maximum price per unit hour that you are willing to pay for a Spot Instance.

      We do not recommend using this parameter because it can lead to increased interruptions. If you do not specify this parameter, you will pay the current Spot price.

      If you specify a maximum price, your instances will be interrupted more frequently than if you do not specify this parameter.

    • getSubnetId

      @Stability(Stable) @Nullable default String getSubnetId()
      The ID of the subnet in which to launch the instances.

    • getWeightedCapacity

      @Stability(Stable) @Nullable default Number getWeightedCapacity()
      The number of units provided by the specified instance type.

    • builder

      @Stability(Stable) static CfnSpotFleet.LaunchTemplateOverridesProperty.Builder builder()
      Returns:
      a CfnSpotFleet.LaunchTemplateOverridesProperty.Builder of CfnSpotFleet.LaunchTemplateOverridesProperty
