Hi. I need to execute some code after a CloudFormation Stack (which is managed by `@pulumi/eks` module) gets created (CREATE_COMPLETE status). Is there a way to hook up to such event in Pulumi?

if you run the code inside an `apply()` it will run when the resource has registered. What code are you trying to run exactly?

That's a good idea. Thanks.
Need to add a couple tags on an ASG that gets created when a new node group for EKS is created. eks.NodeGroup() propagates tags from CF to ASG to instances and adding/changing/deleting a single tag results in NodeGroup update and recreation of launch configuration. I'm trying to avoid that. Just need to add a tag for cluster-autoscaler to tell it which ASGs to manage and which not to.

I was thinking I can use transformation but templateBody property of aws.cloudformation.Stack class is readonly, so I can't add a tag this way

You can do this with the tag resource, see here:
