get-template-summary

Description

Returns information about a new or existing template. The GetTemplateSummary action is useful for viewing parameter information, such as default parameter values and parameter types, before you create or update a stack or stack set.

You can use the GetTemplateSummary action when you submit a template, or you can get template information for a stack set, or a running or deleted stack.

For deleted stacks, GetTemplateSummary returns the template information for up to 90 days after the stack has been deleted. If the template doesn't exist, a ValidationError is returned.

Options

--template-body (string)

Structure containing the template body with a minimum length of 1 byte and a maximum length of 51,200 bytes.

Conditional: You must specify only one of the following parameters: StackName , StackSetName , TemplateBody , or TemplateURL .

--template-url (string)

Location of file containing the template body. The URL must point to a template (max size: 460,800 bytes) that's located in an Amazon S3 bucket or a Systems Manager document. The location for an Amazon S3 bucket must start with https:// .

Conditional: You must specify only one of the following parameters: StackName , StackSetName , TemplateBody , or TemplateURL .

--stack-name (string)

The name or the stack ID that's associated with the stack, which aren't always interchangeable. For running stacks, you can specify either the stack's name or its unique stack ID. For deleted stack, you must specify the unique stack ID.

Conditional: You must specify only one of the following parameters: StackName , StackSetName , TemplateBody , or TemplateURL .

--stack-set-name (string)

The name or unique ID of the stack set from which the stack was created.

Conditional: You must specify only one of the following parameters: StackName , StackSetName , TemplateBody , or TemplateURL .

--call-as (string)

[Service-managed permissions] Specifies whether you are acting as an account administrator in the organization's management account or as a delegated administrator in a member account.

By default, SELF is specified. Use SELF for stack sets with self-managed permissions.

  • If you are signed in to the management account, specify SELF .
  • If you are signed in to a delegated administrator account, specify DELEGATED_ADMIN . Your Amazon Web Services account must be registered as a delegated administrator in the management account. For more information, see Register a delegated administrator in the CloudFormation User Guide .

Possible values:

  • SELF
  • DELEGATED_ADMIN

--template-summary-config (structure)

Specifies options for the GetTemplateSummary API action.

TreatUnrecognizedResourceTypesAsWarnings -> (boolean)

If set to True , any unrecognized resource types generate warnings and not an error. Any unrecognized resource types are returned in the Warnings output parameter.

Shorthand Syntax:

TreatUnrecognizedResourceTypesAsWarnings=boolean

JSON Syntax:

{
  "TreatUnrecognizedResourceTypesAsWarnings": true|false
}

--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.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .
