Indicates the type of instance launches that the Capacity Reservation Fleet accepts. All Capacity Reservations in the Fleet inherit this instance matching criteria.

Instances do not need to explicitly target a Capacity Reservation Fleet to use its reserved capacity.

Valid Values: open

Required: No
