You can only modify a Spot Fleet request of type maintain.
While the Spot Fleet request is being modified, it is in the modifying
state.
To scale up your Spot Fleet, increase its target capacity. The Spot Fleet launches the
additional Spot Instances according to the allocation strategy for the Spot Fleet
request. If the allocation strategy is lowestPrice, the Spot Fleet launches
instances using the Spot Instance pool with the lowest price. If the allocation strategy
is diversified, the Spot Fleet distributes the instances across the Spot
Instance pools. If the allocation strategy is capacityOptimized, Spot Fleet
launches instances from Spot Instance pools with optimal capacity for the number of instances
that are launching.
To scale down your Spot Fleet, decrease its target capacity. First, the Spot Fleet
cancels any open requests that exceed the new target capacity. You can request that the
Spot Fleet terminate Spot Instances until the size of the fleet no longer exceeds the
new target capacity. If the allocation strategy is lowestPrice, the Spot
Fleet terminates the instances with the highest price per unit. If the allocation
strategy is capacityOptimized, the Spot Fleet terminates the instances in
the Spot Instance pools that have the least available Spot Instance capacity. If the allocation
strategy is diversified, the Spot Fleet terminates instances across the
Spot Instance pools. Alternatively, you can request that the Spot Fleet keep the fleet
at its current size, but not replace any Spot Instances that are interrupted or that you
terminate manually.
If you are finished with your Spot Fleet for now, but will use it again later, you can
set the target capacity to 0.
