StackResourceSummary / Attribute / drift_information
Information about whether the resource’s actual configuration differs, or has drifted, from its expected configuration, as defined in the stack template and any values specified as template parameters. For more information, see Detecting Unregulated Configuration Changes to Stacks and Resources.
StackResourceDriftStatus (string) –
Status of the resource’s actual configuration compared to its expected configuration.
DELETED: The resource differs from its expected configuration in that it has been deleted.
MODIFIED: The resource differs from its expected configuration.
NOT_CHECKED: CloudFormation hasn’t checked if the resource differs from its expected configuration. Any resources that don’t currently support drift detection have a status of
NOT_CHECKED. For more information, see Resources that Support Drift Detection. If you performed an ContinueUpdateRollback operation on a stack, any resources included in
ResourcesToSkipwill also have a status of
NOT_CHECKED. For more information about skipping resources during rollback operations, see Continue Rolling Back an Update in the CloudFormation User Guide.
IN_SYNC: The resource’s actual configuration matches its expected configuration.
