Instance Attribute Details

#allocation_strategy ⇒ String

The strategy that determines the order of the launch template overrides to use in fulfilling On-Demand capacity.

‘lowest-price` - EC2 Fleet uses price to determine the order, launching the lowest price first.

‘prioritized` - EC2 Fleet uses the priority that you assigned to each launch template override, launching the highest priority first.

Default: ‘lowest-price`

Returns:

  • (String)

  include Aws::Structure
end

#max_total_price ⇒ String

The maximum amount per hour for On-Demand Instances that you’re willing to pay.

<note markdown=“1”> If your fleet includes T instances that are configured as ‘unlimited`, and if their average CPU usage exceeds the baseline utilization, you will incur a charge for surplus credits. The `maxTotalPrice` does not account for surplus credits, and, if you use surplus credits, your final cost might be higher than what you specified for `maxTotalPrice`. For more information, see [Surplus credits can incur charges] in the *EC2 User Guide*.

#min_target_capacity ⇒ Integer

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

Supported only for fleets of type ‘instant`.

At least one of the following must be specified: ‘SingleAvailabilityZone` | `SingleInstanceType`
