**Example 1: To modify the total target capacity of a Capacity Reservation Fleet**

The following ``modify-capacity-reservation-fleet`` example modifies the total target capacity of the specified Capacity Reservation Fleet. When you modify the total target capacity of a Capacity Reservation Fleet, the Fleet automatically creates new Capacity Reservations, or modifies or cancels existing Capacity Reservations in the Fleet to meet the new total target capacity. You can't attempt additional modifications to a Fleet while it is in the ``modifying`` state. ::

    aws ec2 modify-capacity-reservation-fleet \ 
        --capacity-reservation-fleet-id crf-01234567890abcedf \
        --total-target-capacity 160

        "Return": true
    }

    aws ec2 modify-capacity-reservation-fleet \ 
        --capacity-reservation-fleet-id crf-01234567890abcedf \
        --end-date 2022-07-04T23:59:59.000Z
