talos.imageFactory.getUrlsOutput: output does not change despite the schematic changing

[nicoonoclaste]

I've repeatedly run into an issue where the image's URL isn't recomputed, despite Pulumi correctly reporting the Schematic resource as changed.

This is a minified example based on my configuration; running pulumi up, then changing network_config, then re-running pulumi up should cause a change in the installerAmd64 output.

from base64 import b64encode
import yaml, zstd

import pulumi as pu
import pulumiverse_talos as talos


version = "1.12.3"

network_config = """
apiVersion: v1alpha1
kind: VLANConfig
name: mgmt
vlanID: 32
vlanMode: 802.1q
parent: enp0s1
up: True
---
apiVersion: v1alpha1
kind: DHCPv4Config
name: mgmt
clientIdentifier: mac
"""

image_schematic = talos.imagefactory.Schematic(
    "installerSchematic",
    schematic = yaml.dump({
        "customization": {
            "extraKernelArgs": [
                f"talos.config.early={b64encode(zstd.compress(network_config.encode("ASCII"), 22)).decode("ASCII")}"
            ],
        },
    }),
)

pu.export(
    "installerAmd64",
    talos.imagefactory.get_urls_output(
        architecture = "amd64",
        platform = "metal",
        schematic_id = image_schematic.id,
        talos_version = version,
    ).urls.iso_secureboot,
)
