This strategy can only be used if the EC2 Fleet is of type instant

Indicates whether to use unused Capacity Reservations for fulfilling On-Demand capacity.
If you specify use-capacity-reservations-first
, the fleet uses unused
Capacity Reservations to fulfill On-Demand capacity up to the target
On-Demand capacity. If multiple instance pools have unused Capacity
Reservations, the On-Demand allocation strategy (lowest-price
or
prioritized
) is applied. If the number of unused Capacity Reservations
is less than the On-Demand target capacity, the remaining On-Demand
target capacity is launched according to the On-Demand allocation
strategy (lowest-price
or prioritized
).
If you do not specify a value, the fleet fulfils the On-Demand capacity according to the chosen On-Demand allocation strategy.
Possible values:
- use-capacity-reservations-first
