docs suggest that it shouldn't be doing for a headless service: https://www.pulumi.com/docs/reference/pkg/python/pulumi_kubernetes/core/v1/#pulumi_kubernetes.core.v1.Service

Service code:

etcd_service = corev1.Service(
    "etcd",
    metadata={
        "name": "etcd",
        "namespace": base_namespace.metadata["name"],
    },
    spec={
        "clusterIP": "None",
        "ports": [
            {
                "name": "peers",
                "port": 2380,
                "protocol": "TCP",
                "targetPort": 2380,
            },
            {
                "name": "clients",
                "port": 2379,
                "protocol": "TCP",
                "targetPort": 2379,
            },
        ],
        "selector": {
            "component": "etcd",
        },
    },
)

I also tried a literal Python

None

for

"clusterIP"

and got the same result (pretty sure, though, that that's not the right thing to do).

This service is for use by an etcd StatefulSet, which isn't created until after this, so it's never going to find any Pods at this step.

I can always try turning off the await to skip this validation, but the docs seem to say this should work.

Oh, I see. It needs to be headless AND empty (e.g., no

selector

. So I guess I just need to create the StatefulSet first.

I was hoping I could pass

etcd_service.metadata["name"]

to the StatefulSet's spec.ServiceName to DRY this out, but I guess I can't do that.
