kind: NetworkPolicymetadata: name: my-pol
namespace: dev
spec:
podSelector: {}
policyTypes:

    ingress:
  • from:
    • namespaceSelector:
      matchLabels:
      purpose: prod
    • podSelector: {}
      ports:

Nada Nour:

AB:
This network policy will behave like - Any pod in dev namespace will connect to any pod and namespaces that label with ‘purpose: prob’ over 8001 port.
