-- Retrieves the current run-time configuration for the specified fleet. The run-time configuration tells Amazon GameLift how to launch server processes on instances in the fleet.

-- Fleet-related operations include:
--
--     * 'CreateFleet'
--
--     * 'ListFleets'
--
--     * 'DeleteFleet'
--
--     * Describe fleets:
--

--
--     * 'DescribeEC2InstanceLimits'
--
--     * 'DescribeFleetEvents'

--
--     * Update fleets:
--
--     * 'UpdateFleetAttributes'
--
--     * 'UpdateFleetCapacity'
--
--     * 'UpdateFleetPortSettings'
--
--     * 'UpdateRuntimeConfiguration'
