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 does not exist, a ValidationError is returned.

Synopsis

  get-template-summary
[--template-body <value>]
[--template-url <value>]
[--stack-name <value>]
[--stack-set-name <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--template-body (string)

Structure containing the template body with a minimum length of 1 byte and a maximum length of 51,200 bytes. For more information about templates, see Template Anatomy in the AWS CloudFormation User Guide.

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 is located in an Amazon S3 bucket or a Systems Manager document. For more information about templates, see Template Anatomy in the AWS CloudFormation User Guide.

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 is associated with the stack, which are not 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 .

--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.

(structure)

Describes the target resources of a specific type in your import template (for example, all AWS::S3::Bucket resources) and the properties you can provide during the import to identify resources of that type.
