If I perform an

apply()

on an

Output

of a resource, shouldn't the callback only be called when the resource is created and the value is available when doing a

pulumi preview

?

From the docs for apply function - “This function will only be called execution of a ‘pulumi up’ request. It will not run during ‘pulumi preview’ (as the values of resources are of course not known then). It is not available for functions that end up executing in the cloud during runtime. To get the value of the Output during cloud runtime execution, use get().”

Ok thanks, so I must have been doing something wrong here. I'm creating a

k8s.core.v1.Service

resource and calling apply on it's

metadata.name

property, which is an

Output

. If I run

pulumi preview

the callback gets called with

undefined

as value. Am I understanding something wrong here?
