public class CfnWaitConditionHandle
extends CfnResource
implements IInspectable
For Amazon EC2 and Auto Scaling resources, we recommend that you use a
CreationPolicyattribute instead of wait conditions. Add aCreationPolicyattribute to those resources, and use the cfn-signal helper script to signal when an instance creation process has completed successfully.For more information, see Deploying applications on Amazon EC2 with AWS CloudFormation .
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.
Anytime you add a
WaitConditionresource during a stack update or update a resource with a wait condition, you must associate the wait condition with a newWaitConditionHandleresource. 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.
Example:
// The code below shows an example of how to instantiate this type. // The values are placeholders you should change. import software.amazon.awscdk.services.cloudformation.*; CfnWaitConditionHandle cfnWaitConditionHandle = new CfnWaitConditionHandle(this, "MyCfnWaitConditionHandle");
