Cancel (delete) a Spot Fleet request

If you no longer require a Spot Fleet, you can cancel the Spot Fleet request, which deletes the request. After you cancel a fleet request, all Spot requests associated with the fleet are also canceled, so that no new Spot Instances are launched.

When you cancel a Spot Fleet request, you must also specify if you want to terminate all of its instances. These include both On-Demand Instances and Spot Instances.

If you specify that the instances must be terminated when the fleet request is canceled, the fleet request enters the cancelled_terminating state. Otherwise, it enters the cancelled_running state, and the instances continue to run until they are interrupted or you terminate them manually.

To cancel (delete) a Spot Fleet request and terminate its instances using the AWS CLI

Use the cancel-spot-fleet-requests command to cancel the specified Spot Fleet request and terminate its On-Demand Instances and Spot Instances.

aws ec2 cancel-spot-fleet-requests \
    --spot-fleet-request-ids sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE \
    --terminate-instances

Example output

{
    "SuccessfulFleetRequests": [
        {
            "SpotFleetRequestId": "sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE",
            "CurrentSpotFleetRequestState": "cancelled_terminating",
            "PreviousSpotFleetRequestState": "active"
        }
    ],
    "UnsuccessfulFleetRequests": []
}

To cancel (delete) a Spot Fleet request without terminating its instances using the AWS CLI

You can modify the previous command using the --no-terminate-instances parameter to cancel the specified Spot Fleet request without terminating its On-Demand Instances and Spot Instances.

aws ec2 cancel-spot-fleet-requests \
    --spot-fleet-request-ids sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE \
    --no-terminate-instances

Example output

{
    "SuccessfulFleetRequests": [
        {
            "SpotFleetRequestId": "sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE",
            "CurrentSpotFleetRequestState": "cancelled_running",
            "PreviousSpotFleetRequestState": "active"
        }
    ],
    "UnsuccessfulFleetRequests": []
}
