Network Policies issue

[StefanDima14]

Hello everyone!

I face a problem regarding the network policies analyzed by kube-score. I receive a CRITICAL issue in the output of kube-score that says I don't have a network policy attached to my pods. The trick is that I do have network policies attached to my pods, and I can see that in my Openshift under the Network Tab. And also, the network policies are correctly applied and tested.

Here is the implementation:

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
name: allow-backend-to-services
spec:
podSelector:
matchLabels:
policy: backend-service
ingress:
- ports:
- protocol: TCP
port: xxxx

apiVersion: apps/v1
kind: Deployment
metadata:
name: backend-v1
labels:
app: backend-v1
spec:
{{- if not .Values.autoscaling.backend.enabled }}
replicas: {{ .Values.replicaCount.backend }}
{{- end }}
selector:
matchLabels:
app: backend-v1
template:
metadata:
{{- with .Values.podAnnotations.backend }}
annotations: {{- toYaml . | nindent 8 }}
{{- end }}
labels:
app: backend-v1
name: backend-v1
policy: backend-service

    The issue from the kube-score is this: 
    
    [CRITICAL] Pod NetworkPolicy
    · The pod does not have a matching NetworkPolicy
        Create a NetworkPolicy that targets this pod to control who/what
        can communicate with this pod. Note, this feature needs to be
        supported by the CNI implementation used in the Kubernetes cluster
        to have an effect.
        
        Can you help me understand what I am doing wrong?
