Setting AWS CloudFormation Stack Options

After specifying parameters that are defined in the template, you can set additional options for your stack.

You can set the following stack options:

Tags

Tags are arbitrary key-value pairs that can be used to identify your stack for purposes such as cost allocation. For more information about what tags are and how they can be used, see Tagging Your Resources in the Amazon EC2 User Guide.

A Key consists of any alphanumeric characters but must not contain any spaces. Tag keys up to 127 characters long. A Value consists of any alphanumeric characters or spaces. Tag values can be up to 255 characters long.

Notification Options

A new or existing Amazon Simple Notification Service topic where notifications about stack events are sent.

If you create an Amazon SNS topic, you must specify a name and an email address, where stack event notifications are sent.

Timeout

The number of minutes before stack creation times out. If the stack could not be created before the time expires, creation fails due to timeout and the stack is rolled back. By default, the stack creation never times out.

Rollback on failure

Specifies whether the stack should be rolled back if stack creation fails. Typically, you want to accept the default value of Yes. Select No if you want the stack's state retained even if creation fails, such as when you are debugging a stack template.

Stack policy

Defines the resources that you want to protect from unintentional updates during a stack update. By default, all resources can be updated during a stack update. For more information, see Prevent Updates to Stack Resources.

To set stack options

  1. On the Options screen of the Create Stack wizard, you can specify tags or set additional options by expanding the Advanced section.

  2. When you have entered all of your stack options, click Next Step to proceed with reviewing your stack.
