createStack method

Future<CreateStackOutput> createStack({ required String stackName, List<Capability>? capabilities, String? clientRequestToken, bool? disableRollback, bool? enableTerminationProtection, List<String>? notificationARNs, OnFailure? onFailure, List<Parameter>? parameters, List<String>? resourceTypes, String? roleARN, RollbackConfiguration? rollbackConfiguration, String? stackPolicyBody, String? stackPolicyURL, List<Tag>? tags, String? templateBody, String? templateURL, int? timeoutInMinutes, })

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 via the DescribeStacks API.

May throw LimitExceededException. May throw AlreadyExistsException. May throw TokenAlreadyExistsException. May throw InsufficientCapabilitiesException.

Parameter stackName : The name that is associated with the stack. The name must be unique in the Region in which you are creating the stack.

Parameter capabilities : In some cases, you must explicitly acknowledge that your stack template contains certain capabilities in order for AWS CloudFormation to create the stack.

• CAPABILITY_IAM and CAPABILITY_NAMED_IAM

  Some stack templates might include resources that can affect permissions in your AWS account; for example, by creating new AWS Identity and Access Management (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 or CAPABILITY_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, AWS 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.
  • AWS::IAM::AccessKey
  • AWS::IAM::Group
  • AWS::IAM::InstanceProfile
  • AWS::IAM::Policy
  • AWS::IAM::Role
  • AWS::IAM::User
  • AWS::IAM::UserToGroupAddition
  For more information, see Acknowledging IAM Resources in AWS 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 AWS 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.

  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 AWS CloudFormation being notified. For more information, see Using AWS CloudFormation Macros to Perform Custom Processing on Templates.

Parameter clientRequestToken : A unique identifier for this CreateStack request. Specify this token if you plan to retry requests so that AWS CloudFormation knows that you're not attempting to create a stack with the same name. You might retry CreateStack requests to ensure that AWS CloudFormation successfully received them.

All events triggered 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 token token1, then all the StackEvents generated by that operation will have ClientRequestToken set as token1.

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.

Parameter disableRollback : Set to true to disable rollback of the stack if stack creation failed. You can specify either DisableRollback or OnFailure, but not both.

Default: false

Parameter 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 Protecting a Stack From Being Deleted in the AWS CloudFormation User Guide. Termination protection is disabled on stacks by default.

For nested stacks, termination protection is set on the root stack and cannot be changed directly on the nested stack.

Parameter notificationARNs : The Simple Notification Service (SNS) topic ARNs to publish stack related events. You can find your SNS topic ARNs using the SNS console or your Command Line Interface (CLI).

Parameter onFailure : Determines what action will be taken if stack creation fails. This must be one of: DO_NOTHING, ROLLBACK, or DELETE. You can specify either OnFailure or DisableRollback, but not both.

Default: ROLLBACK

Parameter parameters : A list of Parameter structures that specify input parameters for the stack. For more information, see the Parameter data type.

Parameter resourceTypes : The template resource types that you have permissions to work with for this create stack action, such as AWS::EC2::Instance, AWS::EC2::, or Custom::MyCustomInstance. Use the following syntax to describe template resource types: AWS:: (for all AWS resource), Custom:: (for all custom resources), Custom::logical_ID (for a specific custom resource), AWS::service_name:: (for all resources of a particular AWS service), and AWS::service_name::resource_logical_ID (for a specific AWS resource).

If the list of resource types doesn't include a resource that you're creating, the stack creation fails. By default, AWS CloudFormation grants permissions to all resource types. AWS Identity and Access Management (IAM) uses this parameter for AWS CloudFormation-specific condition keys in IAM policies. For more information, see Controlling Access with AWS Identity and Access Management.

Parameter roleARN : The Amazon Resource Name (ARN) of an AWS Identity and Access Management (IAM) role that AWS CloudFormation assumes to create the stack. AWS CloudFormation uses the role's credentials to make calls on your behalf. AWS CloudFormation always uses this role for all future operations on the stack. As long as users have permission to operate on the stack, AWS 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, AWS CloudFormation uses the role that was previously associated with the stack. If no role is available, AWS CloudFormation uses a temporary session that is generated from your user credentials.

Parameter rollbackConfiguration : The rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards.

Parameter stackPolicyBody : Structure containing the stack policy body. For more information, go to Prevent Updates to Stack Resources in the AWS CloudFormation User Guide. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.

Parameter stackPolicyURL : Location of a file containing the stack policy. The URL must point to a policy (maximum size: 16 KB) located in an S3 bucket in the same Region as the stack. You can specify either the StackPolicyBody or the StackPolicyURL parameter, but not both.

Parameter tags : Key-value pairs to associate with this stack. AWS CloudFormation also propagates these tags to the resources created in the stack. A maximum number of 50 tags can be specified.

Parameter templateBody : Structure containing the template body with a minimum length of 1 byte and a maximum length of 51,200 bytes. For more information, go to Template Anatomy in the AWS CloudFormation User Guide.

Conditional: You must specify either the TemplateBody or the TemplateURL parameter, but not both.

Parameter templateURL : Location of file containing the template body. The URL must point to a template (max size: 460,800 bytes) that is located in an Amazon S3 bucket. For more information, go to the Template Anatomy in the AWS CloudFormation User Guide.

Conditional: You must specify either the TemplateBody or the TemplateURL parameter, but not both.

Parameter timeoutInMinutes : The amount of time that can pass before the stack status becomes CREATE_FAILED; if DisableRollback is not set or is set to false, the stack will be rolled back.
