FieldSelector doesn't appear to be filtering properly

[jacobwolfaws]

I'm trying to filter a list of pods based on the node they're on:

podList, err := clientset.CoreV1().Pods("").List(context.Background(), metav1.ListOptions{
FieldSelector: fmt.Sprintf("spec.nodeName=%s", nodeName),
})

but the FieldSelector doesn't appear to be filtering them properly. I'm currently working around this by doing:

for _, pod := range podList.Items {
		if pod.Spec.NodeName == nodeName {
         # Take action here
         }
}
