Add the following NetworkPolicy to your templates directory

metadata:
name: {{ template "name" . }}
spec:
podSelector:
matchLabels:
app: {{ template "name" . }}

helm install ./foo -n foo
Replace the NetworkPolicy with
{{- if .Capabilities.APIVersions.Has "networking.k8s.io/v1" }}
apiVersion: networking.k8s.io/v1
{{- else }}
apiVersion: extensions/v1beta1
{{- end }}
kind: NetworkPolicy
