I do not think this will work for ComponentResource. I only use attributes and arguments supplied to

__init__

eg:

def __init__(self, role_arn: pulumi.Output[str])

there is some async magic behind outputs and inputs I think it may have been easier if entire pulumi decided to support only async

yes but as you can see i need to pass lists of custom input types

which list?

groups

? -> it's actually not a list it is an

Output[Sequence[str]]

it's 1 item

@great-sunset-355 sorry I'll try to explain better, I've a CustomResource called

Cluster

I've made this class

ClusterArgs

that has an attribute

role_mappings

@pulumi.input_type
class ClusterArgs:
    role_mappings: Optional[pulumi.Input[Sequence[pulumi.InputType['RoleMappingArgs']]]] = pulumi.property("role_mappings", default=None)

yeah, I'd say you are out of luck here, as the issue says they are meant for internal use. I've had a lot of debates about the patterns for component resources and so far this is the best pattern I found out to work. https://github.com/mitodl/ol-infrastructure/blob/main/src/ol_infrastructure/components/aws/database.py mayby @red-match-15116 could add something here

It doesn't look like for internal use, this is the code used by the python custom provider boilerplate (this is the code suggested to create new multilanguage stuff) https://github.com/pulumi/pulumi-component-provider-py-boilerplate/blob/master/sdk/python/pulumi_xyz/static_page.py

This is a Pulumi native provider, aka you write the code in Go, and it generates Py, JS, TS, .NET - and uses the internal features

yep but I just did a test and this looks like a bug

I discovered that repo today, when I found out that AWS provider is missing some API calls I'll need a week to play with it, sorry cannot help with that yet

this works:

@pulumi.input_type
class ClusterArgs:

    def __init__(__self__, *,
                 k8s_version: Optional[pulumi.Input[str]] = "1.21"):
        pulumi.set(__self__, "k8s_version", k8s_version)

    @property
    @pulumi.getter(name="k8s_version")
    def k8s_version(self) -> pulumi.Input[str]:
        return pulumi.get(self, "k8s_version")

    @k8s_version.setter
    def k8s_version(self, value: pulumi.Input[str]):
        pulumi.set(self, "k8s_version", value)

are you able to share the whole source? I'd be very interested to learn from it

@little-journalist-4778 just catching up here - you're trying to create a multi language component, right?

nope

just a standard component?

yes

okay, in that case, input types can easily be either pulumi async types

pulumi.Input

or native types: https://github.com/jaxxstorm/pulumi-nginx-demo/blob/main/nginx-ingress/app.py#L12 if you set them as

pulumi.Input

it'll take either an input, or a string

ok but i think the decorator

pulumi.input_type

is necessary

yes it might be, for this class of question you might be better off opening an issue - it seems we're missing docs here

I looked inside the Output.from_input function and is able only to deeply unwrap lists, dicts AND INPUT CLASSES https://github.com/pulumi/pulumi/blob/master/sdk/python/lib/pulumi/output.py#L253
