- [Provider Reference](https://registry.terraform.io/providers/hashicorp/kubernetes/latest/docs/resources/network_policy#match_labels)

### Description{% #description %}

Checks whether any `kubernetes_network_policy` does not target any pod. Validates that `spec.pod_selector.match_labels` contains concrete label key/value pairs that match at least one pod's `metadata.labels` and not unresolved references like `kubernetes_<resource>.<name>`. If no pod matches the selector or the label value appears to be a reference, the rule reports an `IncorrectValue` issue.
