CreateStackInstances

Creates stack instances for the specified accounts, within the specified AWS Regions. A stack instance refers to a stack in a specific account and Region. You must specify at least one value for either Accounts or DeploymentTargets, and you must specify at least one value for Regions.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

Accounts.member.N

[Self-managed permissions] The names of one or more AWS accounts that you want to create stack instances in the specified Region(s) for.

You can specify Accounts or DeploymentTargets, but not both.

Type: Array of strings

Pattern: ^[0-9]{12}$

Required: No

CallAs

[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 AWS account must be registered as a delegated administrator in the management account. For more information, see Register a delegated administrator in the AWS CloudFormation User Guide.

Type: String

Valid Values: SELF | DELEGATED_ADMIN

Required: No

DeploymentTargets

[Service-managed permissions] The AWS Organizations accounts for which to create stack instances in the specified AWS Regions.

You can specify Accounts or DeploymentTargets, but not both.

Type: DeploymentTargets object

Required: No

OperationId

The unique identifier for this stack set operation.

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

Repeating this stack set operation with a new operation ID retries all stack instances whose status is OUTDATED.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: [a-zA-Z0-9][-a-zA-Z0-9]*

Required: No

OperationPreferences

Preferences for how CloudFormation performs this stack set operation.

Type: StackSetOperationPreferences object

Required: No

ParameterOverrides.member.N

A list of stack set parameters whose values you want to override in the selected stack instances.

Any overridden parameter values will be applied to all stack instances in the specified accounts and AWS Regions. When specifying parameters and their values, be aware of how CloudFormation sets parameter values during stack instance operations:

To override the current value for a parameter, include the parameter and specify its value.
To leave an overridden parameter set to its present value, include the parameter and specify UsePreviousValue as true. (You can't specify both a value and set UsePreviousValue to true.)
To set an overridden parameter back to the value specified in the stack set, specify a parameter list but don't include the parameter in the list.
To leave all parameters set to their present values, don't specify this property at all.

During stack set updates, any parameter values overridden for a stack instance aren't updated, but retain their overridden value.

You can only override the parameter values that are specified in the stack set; to add or delete a parameter itself, use UpdateStackSet to update the stack set template.

Type: Array of Parameter objects

Required: No

Regions.member.N

The names of one or more AWS Regions where you want to create stack instances using the specified AWS accounts.

Type: Array of strings

Pattern: ^[a-zA-Z0-9-]{1,128}$

Required: Yes

StackSetName

The name or unique ID of the stack set that you want to create stack instances from.

Type: String

Required: Yes

Response Elements

The following element is returned by the service.

OperationId

The unique identifier for this stack set operation.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: [a-zA-Z0-9][-a-zA-Z0-9]*

Errors

For information about the errors that are common to all actions, see Common Errors.

HTTP Status Code: 400

OperationIdAlreadyExists

The specified operation ID already exists.

HTTP Status Code: 409

The specified stack set doesn't exist.

HTTP Status Code: 404

StaleRequest
