CfnWaitConditionHandlePropsMixin

class aws_cdk.mixins_preview.aws_cloudformation.mixins.CfnWaitConditionHandlePropsMixin(props, *, strategy=None)

Bases: Mixin

The AWS::CloudFormation::WaitConditionHandle type has no properties.

When you reference the WaitConditionHandle resource by using the Ref function, 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.

For more information, see Create wait conditions in a CloudFormation template in the CloudFormation User Guide .

Anytime you add a WaitCondition resource during a stack update or update a resource with a wait condition, you must associate the wait condition with a new WaitConditionHandle resource. Don’t 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.

Updates aren’t supported for this resource.
