you’re doing the

apply

in the wrong place

stack = pulumi.StackReference(aca_stack_ref)
default_domain = stack.get_output("default_domain")

default_domain.apply(
  lambda domain: domain.split(".")

Many thanks, how could I get the splitted output as an array?

stack = pulumi.StackReference(aca_stack_ref)

default_domain = stack.get_output("default_domain")

default_domain_arr = default_domain.apply(lambda domain: domain.split("."))

lb_resource_group_name = f"mc_{default_domain_arr[0]}-rg_{default_domain_arr[0]}_{default_domain_arr[1]}"

you need to be inside the apply

Isn´t there a way where I can "grab" the output and place it into a "regular" variable, and continue to work with it as a variable?

no, that’s not how Pulumi’s async mechanism works. When you invoke

pulumi up

any output isn’t a known value, so the python interpreter doesn’t know how to handle it. That’s why we have

apply

- that’s our way of saying “this unknown value is known inside the apply so you can use it like a regular string, python”

Roger that, many thanks 🙌

@billowy-army-68599 Wouldn't we be able to do this using the new

StackReference.get_output_details()

method?

yep, that wasn’t shipped when we had this convo 😄

Can StackReference.get_output_details() be used? When I read up on it, it seemd like there was some missing Async functionality in the Pulumi/Python provider ( or something in those lines), so that the functionality was not ready for Python yet.

It can be used, I just tried it yesterday and it worked, but it's not straightforward. Having said that, it's easy once you know. Just search for get_output_details here on Slack and there's a thread where someone posted a piece of code that works

Many thanks, using this worked like a charm:

# config.py

def get_output_details(stack, name):

from pulumi.runtime.sync_await import _sync_await

d = _sync_await(

stack.get_output_details(name)

)

return d.value if d.value is not None else d.secret_value
