detect-stack-set-drift¶

Description¶

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, in addition to 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 information 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 isn’t 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 about 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 `` .

Synopsis¶

  detect-stack-set-drift
--stack-set-name <value>
[--operation-preferences <value>]
[--operation-id <value>]
[--call-as <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--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 CloudFormation performs a stack set operation.

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

RegionConcurrencyType -> (string)

The concurrency type of deploying StackSets operations in Regions, could be in parallel or one Region at a time.

RegionOrder -> (list)

The order of the Regions in where you want to perform the stack operation.

(string)

FailureToleranceCount -> (integer)

The number of accounts, per Region, for which this operation can fail before CloudFormation stops the operation in that Region. If the operation is stopped in a Region, CloudFormation doesn’t attempt the operation in any subsequent Regions.

Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage (but not both).

By default, 0 is specified.

FailureTolerancePercentage -> (integer)

The percentage of accounts, per Region, for which this stack operation can fail before CloudFormation stops the operation in that Region. If the operation is stopped in a Region, CloudFormation doesn’t attempt the operation in any subsequent Regions.

When calculating the number of accounts based on the specified percentage, CloudFormation rounds down to the next whole number.

Conditional: You must specify either FailureToleranceCount or FailureTolerancePercentage , but not both.

By default, 0 is specified.

MaxConcurrentCount -> (integer)

The maximum number of accounts in which to perform this operation at one time. This is dependent on the value of FailureToleranceCount .``MaxConcurrentCount`` is at most one more than the FailureToleranceCount .

Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.

Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage , but not both.

By default, 1 is specified.

MaxConcurrentPercentage -> (integer)

The maximum percentage of accounts in which to perform this operation at one time.

When calculating the number of accounts based on the specified percentage, CloudFormation rounds down to the next whole number. This is true except in cases where rounding down would result is zero. In this case, CloudFormation sets the number as one instead.

Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling.

Conditional: You must specify either MaxConcurrentCount or MaxConcurrentPercentage , but not both.

By default, 1 is specified.

Shorthand Syntax:

RegionConcurrencyType=string,RegionOrder=string,string,FailureToleranceCount=integer,FailureTolerancePercentage=integer,MaxConcurrentCount=integer,MaxConcurrentPercentage=integer

JSON Syntax:

{
  "RegionConcurrencyType": "SEQUENTIAL"|"PARALLEL",
  "RegionOrder": ["string", ...],
  "FailureToleranceCount": integer,
  "FailureTolerancePercentage": integer,
  "MaxConcurrentCount": integer,
  "MaxConcurrentPercentage": integer
}

--operation-id (string)

The ID of the stack set operation.

--call-as (string)

[Service-managed permissions] Specifies whether you are acting as an account administrator in the organization’s management account or as a delegated administrator in a member account.

By default, SELF is specified. Use SELF for stack sets with self-managed permissions.

If you are signed in to the management account, specify SELF .

If you are signed in to a delegated administrator account, specify DELEGATED_ADMIN . Your Amazon Web Services account must be registered as a delegated administrator in the management account. For more information, see Register a delegated administrator in the CloudFormation User Guide .

Possible values:

SELF

DELEGATED_ADMIN

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

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

Output:

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

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

Output¶

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.
