CancelLifecycleExecution

Cancels a lifecycle execution – a single run of lifecycle actions that a lifecycle policy or a StartResourceStateUpdate request started. You can only cancel an execution that hasn't reached a terminal state. Cancellation is asynchronous and doesn't undo completed lifecycle actions.

Request Syntax


PUT /CancelLifecycleExecution HTTP/1.1
Content-type: application/json

{
   "clientToken": "string",
   "lifecycleExecutionId": "string"
}

URI Request Parameters

The request does not use any URI parameters.

Request Body

The request accepts the following data in JSON format.

clientToken

If you retry a request with the same client token, Image Builder returns the original response without running the operation again. For more information, see Ensuring idempotency in the Amazon EC2 API Reference.
