DescribeStackResources

Returns AWS resource descriptions for running and deleted stacks. If StackName is specified, all the associated resources that are part of the stack are returned. If PhysicalResourceId is specified, the associated resources of the stack that the resource belongs to are returned.

Note

Only the first 100 resources will be returned. If your stack has more resources than this, you should use ListStackResources instead.

For deleted stacks, DescribeStackResources returns resource information for up to 90 days after the stack has been deleted.

You must specify either StackName or PhysicalResourceId, but not both. In addition, you can specify LogicalResourceId to filter the returned result. For more information about resources, the LogicalResourceId and PhysicalResourceId, see the AWS CloudFormation User Guide.

Note

A ValidationError is returned if you specify both StackName and PhysicalResourceId in the same request.

Request Parameters

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

LogicalResourceId

The logical name of the resource as specified in the template.

Default: There is no default value.

Type: String

Required: No

PhysicalResourceId

The name or unique identifier that corresponds to a physical instance ID of a resource supported by CloudFormation.

For example, for an Amazon Elastic Compute Cloud (EC2) instance, PhysicalResourceId corresponds to the InstanceId. You can pass the EC2 InstanceId to DescribeStackResources to find which stack the instance belongs to and what other resources are part of the stack.

Required: Conditional. If you don't specify PhysicalResourceId, you must specify StackName.

Default: There is no default value.

Type: String

Required: No

StackName

The name or the unique stack ID that is 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.

Default: There is no default value.

Required: Conditional. If you don't specify StackName, you must specify PhysicalResourceId.

Type: String

Required: No

Response Elements

The following element is returned by the service.

StackResources.member.N

A list of StackResource structures.

Type: Array of StackResource objects
