AutoUpdate

Whether CloudFormation automatically updates the extension in this account and region when a new minor version is published by the extension publisher. Major versions released by the publisher must be manually updated. For more information, see Activating public extensions for use in your account in the AWS CloudFormation User Guide.

DeprecatedStatus

The deprecation status of the extension version.

Valid values include:

ExecutionRoleArn

The Amazon Resource Name (ARN) of the IAM execution role used to register the extension. This applies only to private extensions you have registered in your account. For more information, see RegisterType.

If the registered extension calls any AWS APIs, 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. CloudFormation then assumes that execution role to provide your extension with the appropriate credentials.

Type: String

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

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

IsActivated

Whether the extension is activated in the account and region.

This only applies to public third-party extensions. For all other extensions, CloudFormation returns null.

Type: Boolean

IsDefaultVersion

Whether the specified extension version is set as the default version.

This applies only to private extensions you have registered in your account, and extensions published by AWS. For public third-party extensions, whether they are activated in your account, CloudFormation returns null.

Type: Boolean

LastUpdated

When the specified extension version was registered. This applies only to:

• Private extensions you have registered in your account. For more information, see RegisterType.

• Public extensions you have activated in your account with auto-update specified. For more information, see ActivateType.

Type: Timestamp

LatestPublicVersion

Type: String

Length Constraints: Minimum length of 5.

Pattern: ^(0|[1-9]\d*)\.(0|[1-9]\d*)\.(.*)$

LoggingConfig

Contains logging configuration information for private extensions. This applies only to private extensions you have registered in your account. For public extensions, both those provided by AWS and published by third parties, CloudFormation returns null. For more information, see RegisterType.

OriginalTypeName

For public extensions that have been activated for this account and region, the type name of the public extension.

If you specified a TypeNameAlias when enabling the extension in this account and region, CloudFormation treats that alias as the extension's type name within the account and region, not the type name of the public extension. For more information, see Specifying aliases to refer to extensions in the AWS CloudFormation User Guide.

Type: String

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

ProvisioningType

For resource type extensions, the provisioning behavior of the resource type. AWS CloudFormation determines the provisioning type during registration, based on the types of handlers in the schema handler package submitted.

Valid values include:

• FULLY_MUTABLE: The resource type includes an update handler to process updates to the type during stack update operations.

• IMMUTABLE: The resource type doesn't include an update handler, so the type can't be updated and must instead be replaced during stack update operations.

• NON_PROVISIONABLE: The resource type doesn't include all the following handlers, and therefore can't actually be provisioned.

  • create

  • read

  • delete

Type: String

Valid Values: NON_PROVISIONABLE | IMMUTABLE | FULLY_MUTABLE
