ContinueUpdateRollbackRequest Class

Container for the parameters to the ContinueUpdateRollback operation. Continues rolling back a stack from UPDATE_ROLLBACK_FAILED to 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 enters the UPDATE_ROLLBACK_FAILED state when CloudFormation can't roll back all changes after a failed stack update. For example, this might occur when a stack attempts to roll back to an old database that was deleted outside of CloudFormation. Because CloudFormation doesn't know the instance was deleted, it assumes the instance still exists and attempts to roll back to it, causing the update rollback to fail.

For more information, see Continue rolling back an update in the CloudFormation User Guide. For information for troubleshooting a failed update rollback, see Update rollback failed.

Properties

Name	Type	Description
ClientRequestToken	System.String	Gets and sets the property ClientRequestToken. A unique identifier for this `ContinueUpdateRollback` request. Specify this token if you plan to retry requests so that CloudFormation knows that you're not attempting to continue the rollback to a stack with the same name. You might retry `ContinueUpdateRollback` requests to ensure that CloudFormation successfully received them.
ResourcesToSkip	System.Collections.Generic.List<System.String>	Gets and sets the property ResourcesToSkip. A list of the logical IDs of the resources that CloudFormation skips during the continue update rollback operation. You can specify only resources that are in the `UPDATE_FAILED` state because a rollback failed. You can't specify resources that are in the `UPDATE_FAILED` state for other reasons, for example, because an update was canceled. To check why a resource update failed, use the DescribeStackResources action, and view the resource status reason. Specify this property to skip rolling back resources that CloudFormation can't successfully roll back. We recommend that you troubleshoot resources before skipping them. CloudFormation sets the status of the specified resources to `UPDATE_COMPLETE` and continues to roll back the stack. After the rollback is complete, the state of the skipped resources will be inconsistent with the state of the resources in the stack template. Before performing another stack update, you must update the stack or resources to be consistent with each other. If you don't, subsequent stack updates might fail, and the stack will become unrecoverable. Specify the minimum number of resources required to successfully roll back your stack. For example, a failed resource update might cause dependent resources to fail. In this case, it might not be necessary to skip the dependent resources. To skip resources that are part of nested stacks, use the following format: `NestedStackName.ResourceLogicalID`. If you want to specify the logical ID of a stack resource (`Type: AWS::CloudFormation::Stack`) in the `ResourcesToSkip` list, then its corresponding embedded stack must be in one of the following states: `DELETE_IN_PROGRESS`, `DELETE_COMPLETE`, or `DELETE_FAILED`. Don't confuse a child stack's name with its corresponding logical ID defined in the parent stack. For an example of a continue update rollback operation with nested stacks, see Continue rolling back from failed nested stack updates.
RoleARN	System.String	Gets and sets the property RoleARN. The Amazon Resource Name (ARN) of an IAM role that CloudFormation assumes to roll back the stack. CloudFormation uses the role's credentials to make calls on your behalf. CloudFormation always uses this role for all future operations on the stack. Provided that users have permission to operate on the stack, CloudFormation uses this role even if the users don't have permission to pass it. Ensure that the role grants least permission. If you don't specify a value, CloudFormation uses the role that was previously associated with the stack. If no role is available, CloudFormation uses a temporary session that's generated from your user credentials.
StackName	System.String	Gets and sets the property StackName. The name or the unique ID of the stack that you want to continue rolling back. Don't specify the name of a nested stack (a stack that was created by using the `AWS::CloudFormation::Stack` resource). Instead, use this operation on the parent stack (the stack that contains the `AWS::CloudFormation::Stack` resource).
