describe-type

Description

Returns detailed information about an extension that has been registered.

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

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  describe-type
[--type <value>]
[--type-name <value>]
[--arn <value>]
[--version-id <value>]
[--cli-input-json <value>]
[--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

--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.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. 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.

Examples

To display type information

The following describe-type example displays information for the specified type.

aws cloudformation describe-type \
    --type-name My::Logs::LogGroup \
    --type RESOURCE

Output

Arn -> (string)

The Amazon Resource Name (ARN) of the extension.

Type -> (string)

The kind of extension.

TypeName -> (string)

The name of the registered extension.

DefaultVersionId -> (string)

The ID of the default version of the extension. The default version is used when the extension version is not specified.

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

IsDefaultVersion -> (boolean)

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

Description -> (string)

The description of the registered 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)

The provisioning behavior of the extension. 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 extension includes an update handler to process updates to the extension during stack update operations.
  • IMMUTABLE : The extension does not include an update handler, so the extension cannot be updated and must instead be replaced during stack update operations.
  • NON_PROVISIONABLE : The extension does not include all of the following handlers, and therefore cannot actually be provisioned.
    • create
    • read
    • delete

DeprecatedStatus -> (string)

The deprecation status of the extension version.

Valid values include:

  • LIVE : The extension is registered and can be used in CloudFormation operations, dependent on its provisioning behavior and visibility scope.
  • DEPRECATED : The extension has been deregistered and can no longer be used in CloudFormation operations.

LoggingConfig -> (structure)

Contains logging configuration information for an extension.

LogRoleArn -> (string)

The ARN of the role that CloudFormation should assume when sending log entries to CloudWatch logs.

LogGroupName -> (string)

The Amazon CloudWatch log group to which CloudFormation sends error logging information when invoking the type's handlers.

ExecutionRoleArn -> (string)

The Amazon Resource Name (ARN) of the IAM execution role used to register the extension. 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. 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. Currently, AWS CloudFormation marks any types you register as PRIVATE .
  • PUBLIC : The extension is publically visible and usable within any Amazon account.

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.

TimeCreated -> (timestamp)

When the specified extension version was registered.
