instance IP address has not yet been created

Error message

instance IP address has not yet been created

What it means

Returned in Instance.mapToGCE when the instance spec references an Address task (e.IPAddress != nil) but the resolver returns a nil IP — i.e. the Address object exists in the model yet its IPAddress field is unset because the address has not been allocated yet. It indicates a task-dependency/ordering problem, not a GCE API failure.

Solutions

1. Ensure the Address task the instance depends on is created (has an IP) before the instance renders — add/verify the task dependency (e.AddDependency) so Address renders first
2. Run with an explicit static address that is pre-allocated if ordering cannot be guaranteed
3. Re-run the apply: the address may have been created on a prior partially-successful run
