--stack-set-name (string)

The name or unique ID of the stack set that you want to delete stack instances for.

--accounts (list)

[Self-managed permissions] The names of the AWS accounts that you want to delete stack instances for.

You can specify Accounts or DeploymentTargets , but not both.


"string" "string" ...

--deployment-targets (structure)

[Service-managed permissions] The AWS Organizations accounts from which to delete stack instances.

You can specify Accounts or DeploymentTargets , but not both.

JSON Syntax:

  "Accounts": ["string", ...],
  "OrganizationalUnitIds": ["string", ...]

--regions (list)

The Regions where you want to delete stack set instances.


"string" "string" ...

--operation-preferences (structure)

Preferences for how AWS CloudFormation performs this stack set operation.

Shorthand Syntax:


JSON Syntax:

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

--retain-stacks | --no-retain-stacks (boolean)

Removes the stack instances from the specified stack set, but doesn't delete the stacks. You can't reassociate a retained stack or add an existing, saved stack to a new stack set.

For more information, see Stack set operation options .

--operation-id (string)

The unique identifier for this stack set operation.

If you don't specify an operation ID, the SDK generates one automatically.

The operation ID also functions as an idempotency token, to ensure that AWS CloudFormation performs the stack set operation only once, even if you retry the request multiple times. You can retry stack set operation requests to ensure that AWS CloudFormation successfully received them.

Repeating this stack set operation with a new operation ID retries all stack instances whose status is OUTDATED .

--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 delete stack instances

The following delete-stack-instances example deletes instances of a stack set in two accounts in two regions and terminates the stacks.

aws cloudformation delete-stack-instances \
    --stack-set-name my-stack-set \
    --accounts 123456789012 567890123456 \
    --regions us-east-1 us-west-1 \


    "OperationId": "ad49f10c-fd1d-413f-a20a-8de6e2fa8f27"

To delete an empty stack set, use the delete-stack-set command.


OperationId -> (string)

The unique identifier for this stack set operation.
