hi guys,
I have creates a NP to allow flow from NS:APP to NS:DN on port 9200 and restricted all other traffic using below yaml:
apiVersion: http://networking.k8s.io/v1|networking.k8s.io/v1
kind: NetworkPolicy
metadata:
name: default-deny-ingress
namespace: db
spec:
podSelector: {}
policyTypes:

  • Ingress

ingress:

  • from:
  • namespaceSelector:
    matchLabels:
    ns: app
    ports:
  • protocol: TCP
    port: 9200
#2

Md Ishaq R:
i think the port:9200 is not aligned correctly

#3

Md Ishaq R:
align it correctly under the - protocol: TCP

#4

praveen bhat:
ports:

  • protocol: TCP
    port: 9200
#5

praveen bhat:

This works for me - you may ne missing -from in your yaml file. Also label your namespace and use it in the yaml file. Finally, k apply -f net-your.yaml -n your-namespace
