RegisterType - AWS CloudFormation

RegisterType

Registers an extension with the CloudFormation service. Registering an extension makes it available for use in CloudFormation templates in your AWS account, and includes:

  • Validating the extension schema.

  • Determining which handlers, if any, have been specified for the extension.

  • Making the extension available for use in your account.

For more information about how to develop extensions and ready them for registration, see Creating Resource Providers in the CloudFormation CLI User Guide.

You can have a maximum of 50 resource extension versions registered at a time. This maximum is per account and per Region. Use DeregisterType to deregister specific extension versions if necessary.

Once you have initiated a registration request using RegisterType, you can use DescribeTypeRegistration to monitor the progress of the registration request.

Once you have registered a private extension in your account and Region, use SetTypeConfiguration to specify configuration properties for the extension. For more information, see Configuring extensions at the account level in the CloudFormation User Guide.

Request Parameters

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

ClientRequestToken

A unique identifier that acts as an idempotency key for this registration request. Specifying a client request token prevents CloudFormation from generating more than one version of an extension from the same registration request, even if the request is submitted multiple times.

Type: String

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

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

Required: No

ExecutionRoleArn

The Amazon Resource Name (ARN) of the IAM role for CloudFormation to assume when invoking the extension.

For CloudFormation to assume the specified execution role, the role must contain a trust relationship with the CloudFormation service principal (resources.cloudformation.amazonaws.com). For more information about adding trust relationships, see Modifying a role trust policy in the AWS Identity and Access Management User Guide.

If your extension calls AWS APIs in any of its handlers, you must create an IAM execution role that includes the necessary permissions to call those AWS APIs, and provision that execution role in your account. When CloudFormation needs to invoke the resource type handler, AWS CloudFormation assumes this execution role to create a temporary session token, which it then passes to the resource type handler, thereby supplying your resource type with the appropriate credentials.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Pattern: arn:.+:iam::[0-9]{12}:role/.+

Required: No

LoggingConfig

Specifies logging configuration information for an extension.

Type: LoggingConfig object

Required: No

SchemaHandlerPackage

A URL to the S3 bucket containing the extension project package that contains the necessary files for the extension you want to register.

For information about generating a schema handler package for the extension you want to register, see submit in the CloudFormation CLI User Guide.

Note

The user registering the extension must be able to access the package in the S3 bucket. That's, the user needs to have GetObject permissions for the schema handler package. For more information, see Actions, Resources, and Condition Keys for Amazon S3 in the AWS Identity and Access Management User Guide.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 4096.

Required: Yes

Type

The kind of extension.

Type: String

Valid Values: RESOURCE | MODULE | HOOK

Required: No

TypeName

The name of the extension being registered.

We suggest that extension names adhere to the following patterns:

  • For resource types, company_or_organization::service::type.

  • For modules, company_or_organization::service::type::MODULE.

  • For hooks, MyCompany::Testing::MyTestHook.

Note

The following organization namespaces are reserved and can't be used in your extension names:

  • Alexa

  • AMZN

  • Amazon

  • AWS

  • Custom

  • Dev

Type: String

Length Constraints: Minimum length of 10. Maximum length of 204.

Pattern: [A-Za-z0-9]{2,64}::[A-Za-z0-9]{2,64}::[A-Za-z0-9]{2,64}(::MODULE){0,1}

Required: Yes

Response Elements

The following element is returned by the service.

RegistrationToken

The identifier for this registration request.

Use this registration token when calling DescribeTypeRegistration, which returns information about the status and IDs of the extension registration.

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.

CFNRegistry

An error occurred during a CloudFormation registry operation.

HTTP Status Code: 400
