AWS::CloudFormation::WaitConditionHandle

The AWS::CloudFormation::WaitConditionHandle type has no properties. When you reference the WaitConditionHandle resource by using the Ref function, AWS CloudFormation returns a presigned URL. You pass this URL to applications or scripts that are running on your Amazon EC2 instances to send signals to that URL. An associated AWS::CloudFormation::WaitCondition resource checks the URL for the required number of success signals or for a failure signal.

Important

Anytime you add a WaitCondition resource during a stack update, you must associate the wait condition with a new WaitConditionHandle resource. Do not reuse an old wait condition handle that has already been defined in the template. If you reuse a wait condition handle, the wait condition might evaluate old signals from a previous create or update stack command.

Syntax

   "Type" : "AWS::CloudFormation::WaitConditionHandle",
