describe-stack-resources¶

Description¶

Returns Amazon Web Services 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 , go to the CloudFormation User Guide .

Note

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

Synopsis¶

  describe-stack-resources
[--stack-name <value>]
[--logical-resource-id <value>]
[--physical-resource-id <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--stack-name (string)

The name or the unique stack ID that is associated with the stack, which are not 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 do not specify StackName , you must specify PhysicalResourceId .

--logical-resource-id (string)

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

Default: There is no default value.

--physical-resource-id (string)

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 do not specify PhysicalResourceId , you must specify StackName .

Default: There is no default value.

--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.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To get information about a stack resource

The following describe-stack-resources example displays details for the resources in the specified stack.

aws cloudformation describe-stack-resources \
    --stack-name my-stack

Output:
