cancel_capacity_reservation

EC2.Client.cancel_capacity_reservation(**kwargs)

Cancels the specified Capacity Reservation, releases the reserved capacity, and changes the Capacity Reservation’s state to cancelled.

You can cancel a Capacity Reservation that is in the following states:

  • assessing

  • scheduled — requires a cancellation quote. Use CreateCapacityReservationCancellationQuote to generate a quote, then pass the quote ID with ApplyCancellationCharges set to commitment-wind-down. The cancellation charge depends on how close the reservation is to its start date.

  • active and there is no commitment duration or the commitment duration has elapsed.

  • active during the commitment duration — requires a cancellation quote. Use CreateCapacityReservationCancellationQuote to generate a quote, then pass the quote ID with ApplyCancellationCharges set to commitment-wind-down. The Capacity Reservation transitions to cancelling while charges are applied.

  • delayed — the commitment duration is waived, so no cancellation charge applies.

Note

You can’t modify or cancel a Capacity Block. For more information, see Capacity Blocks for ML.

Instances running in the reserved capacity continue running until you stop them. Stopped instances that target the Capacity Reservation can no longer launch. Modify these instances to either target a different Capacity Reservation, launch On-Demand Instance capacity, or run in any open Capacity Reservation that has matching attributes and sufficient capacity.

    The ID of the Capacity Reservation to be cancelled.

  • DryRun (boolean) – Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation. Otherwise, it is UnauthorizedOperation.

  • ApplyCancellationCharges (string) – Specifies the cancellation charge type to apply when cancelling a future-dated Capacity Reservation during its commitment duration. Possible values include commitment-wind-down, which continues billing for the remaining commitment duration without delivering capacity.
