When passing OnDemandOptionsRequest as input to an Aws::Client method, you can use a vanilla Hash:

{
  allocation_strategy: "lowest-price", # accepts lowest-price, prioritized
  capacity_reservation_options: {
    usage_strategy: "use-capacity-reservations-first", # accepts use-capacity-reservations-first
  },
  single_instance_type: false,
  single_availability_zone: false,
  min_target_capacity: 1,
  max_total_price: "String",
}

#allocation_strategy ⇒ String

The order of the launch template overrides to use in fulfilling On-Demand capacity. If you specify lowest-price, EC2 Fleet uses price to determine the order, launching the lowest price first. If you specify prioritized, EC2 Fleet uses the priority that you assigned to each launch template override, launching the highest priority first. If you do not specify a value, EC2 Fleet defaults to lowest-price.

Possible values:

  • lowest-price
