RegisterType - AWS CloudFormation

RegisterType

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

  • Validating the resource schema

  • Determining which handlers have been specified for the resource

  • Making the resource type available for use in your account

For more information on how to develop types and ready them for registeration, see Creating Resource Providers in the CloudFormation CLI User Guide.

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

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

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 a type from the same registeration 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 resource provider. If your resource type 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 provider handler, CloudFormation assumes this execution role to create a temporary session token, which it then passes to the resource provider handler, thereby supplying your resource provider 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 a type.

Type: LoggingConfig object

Required: No

SchemaHandlerPackage

A url to the S3 bucket containing the schema handler package that contains the schema, event handlers, and associated files for the type you want to register.

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

Note

The user registering the resource provider type must be able to access the the schema handler package in the S3 bucket. That is, 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 type.

Currently, the only valid value is RESOURCE.

Type: String

Valid Values: RESOURCE

Required: No

TypeName

The name of the type being registered.

We recommend that type names adhere to the following pattern: company_or_organization::service::type.

  • Amazon

  • AWS

  • Custom

  • Dev

Type: String

Length Constraints: Minimum length of 10. Maximum length of 196.

Pattern: [A-Za-z0-9]{2,64}::[A-Za-z0-9]{2,64}::[A-Za-z0-9]{2,64}

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 type registration.

Type: String

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

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