CfnWaitConditionPropsMixin

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

Bases: Mixin

The AWS::CloudFormation::WaitCondition resource provides a way to coordinate stack resource creation with configuration actions that are external to the stack creation or to track the status of a configuration process.

In these situations, we recommend that you associate a CreationPolicy attribute with the wait condition instead of using a wait condition handle. For more information and an example, see CreationPolicy attribute in the CloudFormation User Guide . If you use a CreationPolicy with a wait condition, don’t specify any of the wait condition’s properties. .. epigraph:

If you use AWS PrivateLink , resources in the VPC that respond to wait conditions must have access to CloudFormation , specific Amazon S3 buckets. Resources must send wait condition responses to a presigned Amazon S3 URL. If they can't send responses to Amazon S3 , CloudFormation won't receive a response and the stack operation fails. For more information, see `Access CloudFormation using an interface endpoint ( AWS PrivateLink ) <https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/vpc-interface-endpoints.html>`_ in the *CloudFormation User Guide* . > For Amazon EC2 and Amazon EC2 Auto Scaling resources, we recommend that you use a ``CreationPolicy`` attribute instead of wait conditions. Add a ``CreationPolicy`` attribute to those resources, and use the ``cfn-signal`` helper script to signal when an instance creation process has completed successfully.

Create a mixin to apply properties to AWS::CloudFormation::WaitCondition.

Parameters:

props (Union[CfnWaitConditionMixinProps, Dict[str, Any]]) – L1 properties to apply.
strategy (Optional[PropertyMergeStrategy]) – (experimental) Strategy for merging nested properties. Default: - PropertyMergeStrategy.MERGE
