CreateStack
Creates a stack as specified in the template. After the call completes successfully, the stack creation starts. You can check the status of the stack through the DescribeStacks operation.
For more information about creating a stack and monitoring stack progress, see Managing Amazon resources as a single unit with CloudFormation stacks in the Amazon CloudFormation User Guide.
Request Parameters
For information about the parameters that are common to all actions, see Common Parameters.
- Capabilities.member.N
-
In some cases, you must explicitly acknowledge that your stack template contains certain capabilities in order for CloudFormation to create the stack.
-
CAPABILITY_IAM
andCAPABILITY_NAMED_IAM
Some stack templates might include resources that can affect permissions in your Amazon Web Services account; for example, by creating new IAM users. For those stacks, you must explicitly acknowledge this by specifying one of these capabilities.
The following IAM resources require you to specify either the
CAPABILITY_IAM
orCAPABILITY_NAMED_IAM
capability.-
If you have IAM resources, you can specify either capability.
-
If you have IAM resources with custom names, you must specify
CAPABILITY_NAMED_IAM
. -
If you don't specify either of these capabilities, CloudFormation returns an
InsufficientCapabilities
error.
If your stack template contains these resources, we recommend that you review all permissions associated with them and edit their permissions if necessary.
For more information, see Acknowledging IAM resources in CloudFormation templates.
-
-
CAPABILITY_AUTO_EXPAND
Some template contain macros. Macros perform custom processing on templates; this can include simple actions like find-and-replace operations, all the way to extensive transformations of entire templates. Because of this, users typically create a change set from the processed template, so that they can review the changes resulting from the macros before actually creating the stack. If your stack template contains one or more macros, and you choose to create a stack directly from the processed template, without first reviewing the resulting changes in a change set, you must acknowledge this capability. This includes the AWS::Include and AWS::Serverless transforms, which are macros hosted by CloudFormation.
If you want to create a stack from a stack template that contains macros and nested stacks, you must create the stack directly from the template using this capability.
Important
You should only create stacks directly from a stack template that contains macros if you know what processing the macro performs.
Each macro relies on an underlying Lambda service function for processing stack templates. Be aware that the Lambda function owner can update the function operation without CloudFormation being notified.
For more information, see Perform custom processing on CloudFormation templates with template macros.
Note
Only one of the
Capabilities
andResourceType
parameters can be specified.Type: Array of strings
Valid Values:
CAPABILITY_IAM | CAPABILITY_NAMED_IAM | CAPABILITY_AUTO_EXPAND
Required: No
-
- ClientRequestToken
-
A unique identifier for this
CreateStack
request. Specify this token if you plan to retry requests so that CloudFormation knows that you're not attempting to create a stack with the same name. You might retryCreateStack
requests to ensure that CloudFormation successfully received them.All events initiated by a given stack operation are assigned the same client request token, which you can use to track operations. For example, if you execute a
CreateStack
operation with the tokentoken1
, then all theStackEvents
generated by that operation will haveClientRequestToken
set astoken1
.In the console, stack operations display the client request token on the Events tab. Stack operations that are initiated from the console use the token format Console-StackOperation-ID, which helps you easily identify the stack operation . For example, if you create a stack using the console, each stack event would be assigned the same token in the following format:
Console-CreateStack-7f59c3cf-00d2-40c7-b2ff-e75db0987002
.Type: String
Length Constraints: Minimum length of 1. Maximum length of 128.

- DisableRollback
-
Set to
true
to disable rollback of the stack if stack creation failed. You can specify eitherDisableRollback
orOnFailure
, but not both.Default:
false
Type: Boolean
Required: No
- EnableTerminationProtection
-
Whether to enable termination protection on the specified stack. If a user attempts to delete a stack with termination protection enabled, the operation fails and the stack remains unchanged. For more information, see Protect CloudFormation stacks from being deleted in the Amazon CloudFormation User Guide. Termination protection is deactivated on stacks by default.
For nested stacks, termination protection is set on the root stack and can't be changed directly on the nested stack.
Type: Boolean
Required: No
- NotificationARNs.member.N
-
The Amazon SNS topic ARNs to publish stack related events. You can find your Amazon SNS topic ARNs using the Amazon SNS console or your Command Line Interface (CLI).
Type: Array of strings
Array Members: Maximum number of 5 items.
Required: No
- OnFailure
-
Determines what action will be taken if stack creation fails. This must be one of:
DO_NOTHING
,ROLLBACK
, orDELETE
. You can specify eitherOnFailure
orDisableRollback
, but not both.Default:
ROLLBACK
Type: String
Valid Values:
DO_NOTHING | ROLLBACK | DELETE
Required: No
- Parameters.member.N
-
A list of
Parameter
structures that specify input parameters for the stack. For more information, see the Parameter data type.Type: Array of Parameter objects
Required: No
- ResourceTypes.member.N
-
The template resource types that you have permissions to work with for this create stack action, such as
AWS::EC2::Instance
,AWS::EC2::*
, orCustom::MyCustomInstance
. Use the following syntax to describe template resource types:AWS::*
(for all Amazon resources),Custom::*
(for all custom resources),Custom::logical_ID
(for a specific custom resource),AWS::service_name::*
(for all resources of a particular Amazon service), andAWS::service_name::resource_logical_ID
(for a specific Amazon resource).If the list of resource types doesn't include a resource that you're creating, the stack creation fails. By default, CloudFormation grants permissions to all resource types. IAM uses this parameter for CloudFormation-specific condition keys in IAM policies. For more information, see Control access with Amazon Identity and Access Management.

Only one of the
Capabilities
andResourceType
parameters can be specified.Type: Array of strings
Length Constraints: Minimum length of 1. Maximum length of 256.

false
Type: Boolean
Required: No
- RoleARN
-
The Amazon Resource Name (ARN) of an IAM role that CloudFormation assumes to create the stack. CloudFormation uses the role's credentials to make calls on your behalf. CloudFormation always uses this role for all future operations on the stack. Provided that users have permission to operate on the stack, CloudFormation uses this role even if the users don't have permission to pass it. Ensure that the role grants least privilege.
If you don't specify a value, CloudFormation uses the role that was previously associated with the stack. If no role is available, CloudFormation uses a temporary session that's generated from your user credentials.
