Calling [toJSON] on an [Output<T>] is not supported.


            To get the value of an Output as a JSON value or JSON string consider either:
                1: o.apply(v => v.toJSON())
                2: o.apply(v => JSON.stringify(v))

            See <https://pulumi.io/help/outputs> for more details.

            This function may throw in a future version of @pulumi/pulumi.

This is caused because you're calling 
stringify()
on a an object that contains outputs. You're calling 
apply()
on k0sconfig which is necessary, but k0sconfig itself contains outputs.
You have a few options here, such as delegating to Pulumi like Stew suggests. Or adding parameters to 
all()
(are apiVersion and kind outputs?) and nesting calls to 
apply()
(are n.role and n.ip outputs?).
Or you could find the nested-unwrapping logic that Pulumi uses and see if you can call it yourself, or rewrite it.

Looking at your 
k0sconfig
declaration, I see 
k0sctrl.apiVersion
and 
k0sctrl.kind
inside the body of the function - are those outputs as well?

Great minds think alike 🙂 That was my question 2 lines up ☝️

It's possibly cleaner (not sure on how it looks in Python) to update 
pulumi.all()
to have 
nodes
and 
k0sctrl.kind
as parameters. Achieves the same thing without having to await a promise inside the block.

Not sure why I thought all this was in Python.. I'm answering too many questions, maybe...
