Error creating `CustomResource` with configuration NOT under `spec`

[stanislav-zaprudskiy]

Creating a Kubernetes custom resource which expects its specification under a custom key, e.g. under .configuration key (compared to the typical .spec key), fails complaining that that required key is missing.

Also, Pulumi does not show that key in diff (it shows others keys, however, e.g. .kind, .metadata, etc).

Steps to reproduce

postgres_operator = Chart(
    "postgres-operator",
    ChartOpts(
        chart="postgres-operator",
        version="1.7.0",
        fetch_opts=FetchOpts(
            repo="https://opensource.zalando.com/postgres-operator/charts/postgres-operator/"
        ),
        namespace="default",
    )
)

Expected: chart is installed Actual: chart is not installed, with the following error:

error: resource postgres-operator/postgres-operator was not successfully created by the Kubernetes API server : OperatorConfiguration.acid.zalan.do "postgres-operator" is invalid: configuration: Required value

Additional notes

Applying the following transformation, which rewrites .configuration into .spec, fixes the issue:

def change_configuration_to_spec(obj):
    if (
        obj["kind"] == "CustomResourceDefinition"
        and obj["metadata"]["name"] == "operatorconfigurations.acid.zalan.do"
    ):
        for version in obj["spec"]["versions"]:
            if version["additionalPrinterColumns"]:
                for column in version["additionalPrinterColumns"]:
                    if (
                        column["jsonPath"]
                            and column["jsonPath"].startswith(".configuration")
                    ):
                        column["jsonPath"] = re.sub(
                            r'^\.configuration',
                            '.spec',
                            column["jsonPath"]
                        )

            new_required = []
            for req in version["schema"]["openAPIV3Schema"]["required"]:
                if req == "configuration":
                    req = "spec"
                new_required.append(req)
            version["schema"]["openAPIV3Schema"]["required"] = new_required

            version["schema"]["openAPIV3Schema"]["properties"]["spec"] = (
                version["schema"]["openAPIV3Schema"]["properties"]
                ["configuration"])
            del (version["schema"]["openAPIV3Schema"]["properties"]
                 ["configuration"])

    if obj["kind"] == "OperatorConfiguration":
        obj["spec"] = obj["configuration"]
        del obj["configuration"]

Just for completeness - transformation makes the chart manifests installable, but the operator itself doesn't work as it is looking for .configration key in the CR.

@lblackstone Could you please take a look?

Interesting -- I wonder if this issue is specific to Python. Have you tried with any of the other SDKs?
