CreateStack

Description

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.

Request Parameters

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

Capabilities.member.N

A list of capabilities that you must specify before AWS CloudFormation can create or update certain stacks. Some stack templates might include resources that can affect permissions in your AWS account. For those stacks, you must explicitly acknowledge their capabilities by specifying this parameter.

Currently, the only valid value is CAPABILITY_IAM, which is required for the following resources: AWS::CloudFormation::Stack, AWS::IAM::AccessKey, AWS::IAM::Group, AWS::IAM::InstanceProfile, AWS::IAM::Policy, AWS::IAM::Role, AWS::IAM::User, and AWS::IAM::UserToGroupAddition. If your stack template contains these resources, we recommend that you review any permissions associated with them. If you don't specify this parameter, this action returns an InsufficientCapabilities error.

Type: String list

Valid Values: CAPABILITY_IAM

Required: No

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

Type: Boolean

Required: No

NotificationARNs.member.N

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).

Type: String list

Length constraints: Minimum of 0 item(s) in the list. Maximum of 5 item(s) in the list.

Required: No

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

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.

Type: Parameter list

Required: No

StackName

The name that is associated with the stack. The name must be unique in the region in which you are creating the stack.

Note

A stack name can contain only alphanumeric characters (case sensitive) and hyphens. It must start with an alphabetic character and cannot be longer than 255 characters.

Type: String

Required: Yes

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.

Type: String

Length constraints: Minimum length of 1. Maximum length of 16384.

Required: No

StackPolicyURL

Location of a file containing the stack policy. The URL must point to a policy (max size: 16KB) 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.

Type: String

Length constraints: Minimum length of 1. Maximum length of 1350.

Required: No

Tags.member.N

A set of user-defined Tags to associate with this stack, represented by key/value pairs. Tags defined for the stack are propagated to EC2 resources that are created as part of the stack. A maximum number of 10 tags can be specified.

Type: Tag list

Required: No

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.

Type: String

Length constraints: Minimum length of 1.

Required: No

TemplateURL

Location of file containing the template body. The URL must point to a template (max size: 307,200 bytes) located in an S3 bucket in the same region as the stack. 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.

Type: String

Length constraints: Minimum length of 1. Maximum length of 1024.

Required: No

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.

Type: Integer

Required: No

Response Elements

The following element is returned in a structure named CreateStackResult.

StackId

Unique identifier of the stack.

Type: String

Errors

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

AlreadyExists

Resource with the name requested already exists.

HTTP Status Code: 400

InsufficientCapabilities
