First time using the AWS CLI? See the User Guide for help getting started.

Note: You are viewing the documentation for an older major version of the AWS CLI (version 1).

AWS CLI version 2, the latest major version of AWS CLI, is now stable and recommended for general use. To view this page for the AWS CLI version 2, click here. For more information see the AWS CLI version 2 installation instructions and migration guide.

Detect drift on a stack set. When CloudFormation performs drift detection on a stack set, it performs drift detection on the stack associated with each stack instance in the stack set. For more information, see How CloudFormation Performs Drift Detection on a Stack Set .

DetectStackSetDrift returns the OperationId of the stack set drift detection operation. Use this operation id with `` DescribeStackSetOperation `` to monitor the progress of the drift detection operation. The drift detection operation may take some time, depending on the number of stack instances included in the stack set, as well as the number of resources included in each stack.

Once the operation has completed, use the following actions to return drift information:

  • Use `` DescribeStackSet `` to return detailed informaiton about the stack set, including detailed information about the last completed drift operation performed on the stack set. (Information about drift operations that are in progress is not included.)
  • Use `` ListStackInstances `` to return a list of stack instances belonging to the stack set, including the drift status and last drift time checked of each instance.
  • Use `` DescribeStackInstance `` to return detailed information about a specific stack instance, including its drift status and last drift time checked.

For more information on performing a drift detection operation on a stack set, see Detecting Unmanaged Changes in Stack Sets .

You can only run a single drift detection operation on a given stack set at one time.

To stop a drift detection stack set operation, use `` StopStackSetOperation `` .

--stack-set-name <value>
[--operation-preferences <value>]
[--operation-id <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--stack-set-name (string)

The name of the stack set on which to perform the drift detection operation.

--operation-preferences (structure)

The user-specified preferences for how AWS CloudFormation performs a stack set operation.

For more information on maximum concurrent accounts and failure tolerance, see Stack set operation options .

Shorthand Syntax:


JSON Syntax:

  "RegionOrder": ["string", ...],
  "FailureToleranceCount": integer,
  "FailureTolerancePercentage": integer,
  "MaxConcurrentCount": integer,
  "MaxConcurrentPercentage": integer

--operation-id (string)

The ID of the stack set operation.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


To detect drift on a stack set and all associated stack instances

The following detect-stack-set-drift example initiates drift detection operations on the specified stack set, including all the stack instances associated with that stack set, and returns an operation ID that can be used to track the status of the drift operation.

aws cloudformation detect-stack-set-drift \
    --stack-set-name stack-set-drift-example


    "OperationId": "a1b2c3d4-5678-90ab-cdef-EXAMPLE11111"

For more information, see Detecting Unmanaged Configuration Changes in Stack Sets in the AWS CloudFormation Users Guide.


OperationId -> (string)

The ID of the drift detection stack set operation.

you can use this operation id with `` DescribeStackSetOperation `` to monitor the progress of the drift detection operation.
