  • 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 attributes for the instance types.

      When you specify instance attributes, Amazon EC2 will identify instance types with those attributes.

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

    • getInstanceType

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

      mac1.metal is not supported as a launch template override.

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

    • getMaxPrice

      @Stability(Stable) @Nullable default String getMaxPrice()
      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.

    • getPlacement

      @Stability(Stable) @Nullable default Object getPlacement()
      The location where the instance launched, if applicable.

    • getPriority

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

      If the On-Demand AllocationStrategy is set to prioritized , EC2 Fleet uses priority to determine which launch template override to use first in fulfilling On-Demand capacity.

      If the Spot AllocationStrategy is set to capacity-optimized-prioritized , EC2 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.

    • getSubnetId

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

      Separate multiple subnet IDs using commas (for example, subnet-1234abcdeexample1, subnet-0987cdef6example2 ). A request of type instant can have only one subnet ID.

    • getWeightedCapacity

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

    • builder

      @Stability(Stable) static CfnEC2Fleet.FleetLaunchTemplateOverridesRequestProperty.Builder builder()
      Returns:
      a CfnEC2Fleet.FleetLaunchTemplateOverridesRequestProperty.Builder of CfnEC2Fleet.FleetLaunchTemplateOverridesRequestProperty
