See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-type
[--type <value>]
[--type-name <value>]
[--arn <value>]
[--version-id <value>]
[--publisher-id <value>]
[--public-version-number <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--type (string)

The kind of extension.

Conditional: You must specify either TypeName and Type , or Arn .

Possible values:

  • RESOURCE

  • MODULE

  • HOOK

--type-name (string)

The name of the extension.

Conditional: You must specify either TypeName and Type , or Arn .

--arn (string)

The Amazon Resource Name (ARN) of the extension.

Conditional: You must specify either TypeName and Type , or Arn .

--version-id (string)

The ID of a specific version of the extension. The version ID is the value at the end of the Amazon Resource Name (ARN) assigned to the extension version when it is registered.

If you specify a VersionId , DescribeType returns information about that specific extension version. Otherwise, it returns information about the default extension version.

--publisher-id (string)

The publisher ID of the extension publisher.

Extensions provided by Amazon are not assigned a publisher ID.

--public-version-number (string)

The version number of a public third-party extension.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Output

Arn -> (string)

The Amazon Resource Name (ARN) of the extension.

Type -> (string)

The kind of extension.

TypeName -> (string)

The name of the extension.

If the extension is a public third-party type you have activated with a type name alias, CloudFormation returns the type name alias. For more information, see ActivateType .

DefaultVersionId -> (string)

The ID of the default version of the extension. The default version is used when the extension version isn’t specified.

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

To set the default version of an extension, use `` SetTypeDefaultVersion `` .

IsDefaultVersion -> (boolean)

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 Amazon. For public third-party extensions, whether or not they are activated in your account, CloudFormation returns null .

TypeTestsStatus -> (string)

The contract test status of the registered extension version. To return the extension test status of a specific extension version, you must specify VersionId .

This applies only to registered private extension versions. CloudFormation doesn’t return this information for public extensions, whether or not they are activated in your account.

  • PASSED : The extension has passed all its contract tests. An extension must have a test status of PASSED before it can be published. For more information, see Publishing extensions to make them available for public use in the CloudFormation Command Line Interface User Guide .

  • FAILED : The extension has failed one or more contract tests.

  • IN_PROGRESS : Contract tests are currently being performed on the extension.

  • NOT_TESTED : Contract tests haven’t been performed on the extension.

TypeTestsStatusDescription -> (string)

The description of the test status. To return the extension test status of a specific extension version, you must specify VersionId .

This applies only to registered private extension versions. CloudFormation doesn’t return this information for public extensions, whether or not they are activated in your account.

Description -> (string)

The description of the extension.

Schema -> (string)

The schema that defines the extension.

For more information on extension schemas, see Resource Provider Schema in the CloudFormation CLI User Guide .

ProvisioningType -> (string)

For resource type extensions, the provisioning behavior of the resource type. 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

DeprecatedStatus -> (string)

The deprecation status of the extension version.

Valid values include:

  • LIVE : The extension is activated or registered and can be used in CloudFormation operations, dependent on its provisioning behavior and visibility scope.

  • DEPRECATED : The extension has been deactivated or deregistered and can no longer be used in CloudFormation operations.

For public third-party extensions, CloudFormation returns null .

LoggingConfig -> (structure)

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 Amazon and published by third parties, CloudFormation returns null . For more information, see RegisterType .

LogRoleArn -> (string)

The Amazon Resource Name (ARN) of the role that CloudFormation should assume when sending log entries to CloudWatch Logs.

LogGroupName -> (string)

The Amazon CloudWatch Logs group to which CloudFormation sends error logging information when invoking the extension’s handlers.

RequiredActivatedTypes -> (list)

For extensions that are modules, the public third-party extensions that must be activated in your account in order for the module itself to be activated.

(structure)

For extensions that are modules, a public third-party extension that must be activated in your account in order for the module itself to be activated.

For more information, see Activating public modules for use in your account in the CloudFormation User Guide .

TypeNameAlias -> (string)

An alias assigned to the public extension, in this account and region. If you specify an alias for the extension, CloudFormation treats the alias as the extension type name within this account and region. You must use the alias to refer to the extension in your templates, API calls, and CloudFormation console.

OriginalTypeName -> (string)

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 CloudFormation User Guide .

PublisherId -> (string)

The publisher ID of the extension publisher.

SupportedMajorVersions -> (list)

A list of the major versions of the extension type that the macro supports.

(integer)

ExecutionRoleArn -> (string)

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 Amazon Web Services APIs, you must create an * IAM execution role * that includes the necessary permissions to call those Amazon Web Services APIs, and provision that execution role in your account. CloudFormation then assumes that execution role to provide your extension with the appropriate credentials.

Visibility -> (string)

The scope at which the extension is visible and usable in CloudFormation operations.

Valid values include:

  • PRIVATE : The extension is only visible and usable within the account in which it is registered. CloudFormation marks any extensions you register as PRIVATE .

SourceUrl -> (string)

The URL of the source code for the extension.

DocumentationUrl -> (string)

The URL of a page providing detailed documentation for this extension.

LastUpdated -> (timestamp)

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 .

TimeCreated -> (timestamp)

When the specified private extension version was registered or activated in your account.

ConfigurationSchema -> (string)

A JSON string that represent the current configuration data for the extension in this account and region.

To set the configuration data for an extension, use SetTypeConfiguration . For more information, see Configuring extensions at the account level in the CloudFormation User Guide .

This applies only to public third-party extensions. For private registered extensions, and extensions provided by Amazon Web Services, CloudFormation returns null .

OriginalTypeName -> (string)

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 CloudFormation User Guide .
