DescribeStacks - AWS CloudFormation

DescribeStacks

Returns the description for the specified stack; if no stack name was specified, then it returns the description for all the stacks created. For more information about a stack's event history, see Understand CloudFormation stack creation events in the AWS CloudFormation User Guide.

Note

If the stack doesn't exist, a ValidationError is returned.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

NextToken

A string that identifies the next page of stacks that you want to retrieve.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Required: No

StackName

Note

If you don't pass a parameter to StackName, the API returns a response that describes all resources in the account, which can impact performance. This requires ListStacks and DescribeStacks permissions.

Consider using the ListStacks API if you're not passing a parameter to StackName.

The IAM policy below can be added to IAM policies when you want to limit resource-level permissions and avoid returning a response when no parameter is sent in the request:

{ "Version": "2012-10-17", "Statement": [{ "Effect": "Deny", "Action": "cloudformation:DescribeStacks", "NotResource": "arn:aws:cloudformation:*:*:stack/*/*" }] }

The name or the unique stack ID that's associated with the stack, which aren't always interchangeable:

Running stacks: You can specify either the stack's name or its unique stack ID.
Deleted stacks: You must specify the unique stack ID.

Type: String

Required: No

Response Elements

The following elements are returned by the service.

NextToken

If the output exceeds 1 MB in size, a string that identifies the next page of stacks. If no additional page exists, this value is null.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Stacks.member.N

A list of stack structures.

Type: Array of Stack objects

Errors

For information about the errors that are common to all actions, see Common Errors.
