AccountGateResult Structure that contains the results of the account gate function which AWS CloudFormation invokes, if present, before proceeding with a stack set operation in an account and region. For each account and region, AWS CloudFormation lets you specify a Lamdba function that encapsulates any requirements that must be met before CloudFormation can proceed with a stack set operation in that account and region. CloudFormation invokes the function each time a stack set operation is requested for that account and region; if the function returns FAILED, CloudFormation cancels the operation in that account and region, and sets the stack set operation result status for that account and region to FAILED. For more information, see Configuring a target account gate.

 AccountLimit The AccountLimit data type. For more information about account limits, see AWS CloudFormation Limits in the AWS CloudFormation User Guide.

 AlreadyExistsException CloudFormation exception

 CancelUpdateStackRequest Container for the parameters to the CancelUpdateStack operation. Cancels an update on the specified stack. If the call completes successfully, the stack rolls back the update and reverts to the previous stack configuration. You can cancel only stacks that are in the UPDATE_IN_PROGRESS state.

 CancelUpdateStackResponse This is the response object from the CancelUpdateStack operation.

 Change The Change structure describes the changes AWS CloudFormation will perform if you execute the change set.

 ChangeSetNotFoundException CloudFormation exception

 ChangeSetSummary The ChangeSetSummary structure describes a change set, its status, and the stack with which it's associated.

 ContinueUpdateRollbackRequest Container for the parameters to the ContinueUpdateRollback operation. For a specified stack that is in the UPDATE_ROLLBACK_FAILED state, continues rolling it back to the UPDATE_ROLLBACK_COMPLETE state. Depending on the cause of the failure, you can manually fix the error and continue the rollback. By continuing the rollback, you can return your stack to a working state (the UPDATE_ROLLBACK_COMPLETE state), and then try to update the stack again. A stack goes into the UPDATE_ROLLBACK_FAILED state when AWS CloudFormation cannot roll back all changes after a failed stack update. For example, you might have a stack that is rolling back to an old database instance that was deleted outside of AWS CloudFormation. Because AWS CloudFormation doesn't know the database was deleted, it assumes that the database instance still exists and attempts to roll back to it, causing the update rollback to fail.

 ContinueUpdateRollbackResponse The output for a ContinueUpdateRollback action.

 CreateChangeSetRequest Container for the parameters to the CreateChangeSet operation. Creates a list of changes that will be applied to a stack so that you can review the changes before executing them. You can create a change set for a stack that doesn't exist or an existing stack. If you create a change set for a stack that doesn't exist, the change set shows all of the resources that AWS CloudFormation will create. If you create a change set for an existing stack, AWS CloudFormation compares the stack's information with the information that you submit in the change set and lists the differences. Use change sets to understand which resources AWS CloudFormation will create or change, and how it will change resources in an existing stack, before you create or update a stack. To create a change set for a stack that doesn't exist, for the ChangeSetType parameter, specify CREATE. To create a change set for an existing stack, specify UPDATE for the ChangeSetType parameter. After the CreateChangeSet call successfully completes, AWS CloudFormation starts creating the change set. To check the status of the change set or to review it, use the DescribeChangeSet action. When you are satisfied with the changes the change set will make, execute the change set by using the ExecuteChangeSet action. AWS CloudFormation doesn't make changes until you execute the change set.

 CreateChangeSetResponse The output for the CreateChangeSet action.

 CreatedButModifiedException CloudFormation exception

 DescribeStackDriftDetectionStatusRequest Container for the parameters to the DescribeStackDriftDetectionStatus operation. Returns information about a stack drift detection operation. A stack drift detection operation detects whether a stack's actual configuration differs, or has drifted, from it's expected configuration, as defined in the stack template and any values specified as template parameters. A stack is considered to have drifted if one or more of its resources have drifted. For more information on stack and resource drift, see Detecting Unregulated Configuration Changes to Stacks and Resources. Use DetectStackDrift to initiate a stack drift detection operation. DetectStackDrift returns a StackDriftDetectionId you can use to monitor the progress of the operation using DescribeStackDriftDetectionStatus. Once the drift detection operation has completed, use DescribeStackResourceDrifts to return drift information about the stack and its resources.

 DescribeStackDriftDetectionStatusResponse This is the response object from the DescribeStackDriftDetectionStatus operation.

 DescribeStackEventsRequest Container for the parameters to the DescribeStackEvents operation. Returns all stack related events for a specified stack in reverse chronological order.

For a given stack, there will be one StackResourceDrift for each stack resource that has been checked for drift. Resources that have not yet been checked for drift are not included. Resources that do not currently support drift detection are not checked, and so not included. For a list of resources that support drift detection, see Resources that Support Drift Detection. Use DetectStackResourceDrift to detect drift on individual resources, or DetectStackDrift to detect drift on all supported resources for a given stack.

 DescribeStackResourceDriftsResponse This is the response object from the DescribeStackResourceDrifts operation.

 DescribeStackResourceRequest Container for the parameters to the DescribeStackResource operation. Returns a description of the specified resource in the specified stack. For deleted stacks, DescribeStackResource returns resource information for up to 90 days after the stack has been deleted.

 DescribeStackResourceResponse The output for a DescribeStackResource action.

 DescribeStackResourcesRequest Container for the parameters to the DescribeStackResources operation. 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. 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 AWS CloudFormation User Guide. A ValidationError is returned if you specify both StackName and PhysicalResourceId in the same request.

If the stack does not exist, an AmazonCloudFormationException is returned.

 DescribeStacksResponse The output for a DescribeStacks action.

 DetectStackDriftRequest Container for the parameters to the DetectStackDrift operation. Detects whether a stack's actual configuration differs, or has drifted, from it's expected configuration, as defined in the stack template and any values specified as template parameters. For each resource in the stack that supports drift detection, AWS CloudFormation compares the actual configuration of the resource with its expected template configuration. Only resource properties explicitly defined in the stack template are checked for drift. A stack is considered to have drifted if one or more of its resources differ from their expected template configurations. For more information, see Detecting Unregulated Configuration Changes to Stacks and Resources. Use DetectStackDrift to detect drift on all supported resources for a given stack, or DetectStackResourceDrift to detect drift on individual resources. For a list of stack resources that currently support drift detection, see Resources that Support Drift Detection. DetectStackDrift can take up to several minutes, depending on the number of resources contained within the stack. Use DescribeStackDriftDetectionStatus to monitor the progress of a detect stack drift operation. Once the drift detection operation has completed, use DescribeStackResourceDrifts to return drift information about the stack and its resources. When detecting drift on a stack, AWS CloudFormation does not detect drift on any nested stacks belonging to that stack. Perform DetectStackDrift directly on the nested stack itself.

 DetectStackDriftResponse This is the response object from the DetectStackDrift operation.

 DetectStackResourceDriftRequest Container for the parameters to the DetectStackResourceDrift operation. Returns information about whether a resource's actual configuration differs, or has drifted, from it's expected configuration, as defined in the stack template and any values specified as template parameters. This information includes actual and expected property values for resources in which AWS CloudFormation detects drift. Only resource properties explicitly defined in the stack template are checked for drift. For more information about stack and resource drift, see Detecting Unregulated Configuration Changes to Stacks and Resources. Use DetectStackResourceDrift to detect drift on individual resources, or DetectStackDrift to detect drift on all resources in a given stack that support drift detection. Resources that do not currently support drift detection cannot be checked. For a list of resources that support drift detection, see Resources that Support Drift Detection.

 DetectStackResourceDriftResponse This is the response object from the DetectStackResourceDrift operation.

 ExecuteChangeSetRequest Container for the parameters to the ExecuteChangeSet operation. Updates a stack using the input information that was provided when the specified change set was created. After the call successfully completes, AWS CloudFormation starts updating the stack. Use the DescribeStacks action to view the status of the update. When you execute a change set, AWS CloudFormation deletes all other change sets associated with the stack because they aren't valid for the updated stack. If a stack policy is associated with the stack, AWS CloudFormation enforces the policy during the update. You can't specify a temporary stack policy that overrides the current policy.

 ExecuteChangeSetResponse The output for the ExecuteChangeSet action.

 Export The Export structure describes the exported output values for a stack.

 GetStackPolicyRequest Container for the parameters to the GetStackPolicy operation. Returns the stack policy for a specified stack. If a stack doesn't have a policy, a null value is returned.

 ParameterDeclaration The ParameterDeclaration data type.

 PhysicalResourceIdContextKeyValuePair Context information that enables AWS CloudFormation to uniquely identify a resource. AWS CloudFormation uses context key-value pairs in cases where a resource's logical and physical IDs are not enough to uniquely identify that resource. Each context key-value pair specifies a resource that contains the targeted resource.

 PropertyDifference Information about a resource property whose actual value differs from its expected value, as defined in the stack template and any values specified as template parameters. These will be present only for resources whose StackResourceDriftStatus is MODIFIED. For more information, see Detecting Unregulated Configuration Changes to Stacks and Resources.

 RollbackConfiguration Structure containing the rollback triggers for AWS CloudFormation to monitor during stack creation and updating operations, and for the specified monitoring period afterwards. Rollback triggers enable you to have AWS CloudFormation monitor the state of your application during stack creation and updating, and to roll back that operation if the application breaches the threshold of any of the alarms you've specified. For more information, see Monitor and Roll Back Stack Operations.

 RollbackTrigger A rollback trigger AWS CloudFormation monitors during creation and updating of stacks. If any of the alarms you specify goes to ALARM state during the stack operation or within the specified monitoring period afterwards, CloudFormation rolls back the entire stack operation.

 SetStackPolicyRequest Container for the parameters to the SetStackPolicy operation. Sets a stack policy for a specified stack.

 SetStackPolicyResponse This is the response object from the SetStackPolicy operation.

 SignalResourceRequest Container for the parameters to the SignalResource operation. Sends a signal to the specified resource with a success or failure status. You can use the SignalResource API in conjunction with a creation policy or update policy. AWS CloudFormation doesn't proceed with a stack creation or update until resources receive the required number of signals or the timeout period is exceeded. The SignalResource API is useful in cases where you want to send signals from anywhere other than an Amazon EC2 instance.

 SignalResourceResponse This is the response object from the SignalResource operation.

 Stack The Stack data type.

 StackDriftInformation Contains information about whether the stack's actual configuration differs, or has drifted, from its expected configuration, as defined in the stack template and any values specified as template parameters. A stack is considered to have drifted if one or more of its resources have drifted.

 StackDriftInformationSummary Contains information about whether the stack's actual configuration differs, or has drifted, from its expected configuration, as defined in the stack template and any values specified as template parameters. A stack is considered to have drifted if one or more of its resources have drifted.

 StackEvent The StackEvent data type.

 StackInstance An AWS CloudFormation stack, in a specific account and region, that's part of a stack set operation. A stack instance is a reference to an attempted or actual stack in a given account within a given region. A stack instance can exist without a stack—for example, if the stack couldn't be created for some reason. A stack instance is associated with only one stack set. Each stack instance contains the ID of its associated stack set, as well as the ID of the actual stack and the stack status.

 StackInstanceNotFoundException CloudFormation exception

 StackInstanceSummary The structure that contains summary information about a stack instance.

 StackResource The StackResource data type.

 StackResourceDetail Contains detailed information about the specified stack resource.

 StackResourceDrift Contains the drift information for a resource that has been checked for drift. This includes actual and expected property values for resources in which AWS CloudFormation has detected drift. Only resource properties explicitly defined in the stack template are checked for drift. For more information, see Detecting Unregulated Configuration Changes to Stacks and Resources. Resources that do not currently support drift detection cannot be checked. For a list of resources that support drift detection, see Resources that Support Drift Detection. Use DetectStackResourceDrift to detect drift on individual resources, or DetectStackDrift to detect drift on all resources in a given stack that support drift detection.

 StackResourceDriftInformation Contains information about whether the resource's actual configuration differs, or has drifted, from its expected configuration.

 StackResourceDriftInformationSummary Summarizes information about whether the resource's actual configuration differs, or has drifted, from its expected configuration.

 TemplateParameter The TemplateParameter data type.

 TokenAlreadyExistsException CloudFormation exception

 UpdateStackInstancesRequest Container for the parameters to the UpdateStackInstances operation. Updates the parameter values for stack instances for the specified accounts, within the specified regions. A stack instance refers to a stack in a specific account and region. You can only update stack instances in regions and accounts where they already exist; to create additional stack instances, use CreateStackInstances. During stack set updates, any parameters overridden for a stack instance are not updated, but retain their overridden value. You can only update the parameter values that are specified in the stack set; to add or delete a parameter itself, use UpdateStackSet to update the stack set template. If you add a parameter to a template, before you can override the parameter value specified in the stack set you must first use UpdateStackSet to update all stack instances with the updated template and parameter value specified in the stack set. Once a stack instance has been updated with the new parameter, you can then override the parameter value using UpdateStackInstances.

 UpdateStackInstancesResponse This is the response object from the UpdateStackInstances operation.

 UpdateStackRequest The input for UpdateStack action.

 UpdateStackResponse The output for an UpdateStack action.

 UpdateStackSetRequest Container for the parameters to the UpdateStackSet operation. Updates the stack set, and associated stack instances in the specified accounts and regions. Even if the stack set operation created by updating the stack set fails (completely or partially, below or above a specified failure tolerance), the stack set is updated with your changes. Subsequent CreateStackInstances calls on the specified stack set use the updated stack set.

 UpdateStackSetResponse This is the response object from the UpdateStackSet operation.

 UpdateTerminationProtectionRequest Container for the parameters to the UpdateTerminationProtection operation. Updates termination protection for the specified stack. If a user attempts to delete a stack with termination protection enabled, the operation fails and the stack remains unchanged. For more information, see Protecting a Stack From Being Deleted in the AWS CloudFormation User Guide. For nested stacks, termination protection is set on the root stack and cannot be changed directly on the nested stack.

 UpdateTerminationProtectionResponse This is the response object from the UpdateTerminationProtection operation.

 ValidateTemplateRequest Container for the parameters to the ValidateTemplate operation. Validates a specified template. AWS CloudFormation first checks if the template is valid JSON. If it isn't, AWS CloudFormation checks if the template is valid YAML. If both these checks fail, AWS CloudFormation returns a template validation error.

 ValidateTemplateResponse The output for ValidateTemplate action.
