Help with CKA Mock Exam 3- question 5


Hi Team, need small help with mock exam 3, question -5. If i have pod selector as {} in ingress section, its showing failed in review, can you please confirm whats wrong if i define my yaml like attached. Thank You.

You need to make the network policy with name ingress-to-nptest , Port 53 is used to be able to reach the service using a service name instead of IP. Check the following:

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: ingress-to-nptest
  namespace: default
spec:
  podSelector:
    matchLabels:
      run: np-test-1
  policyTypes:
  Ingress
  - from:
    - podSelector: {}
  - ports:
    - protocol: TCP
      port: 80

- ports:
    - protocol: TCP
      port: 53
    - protocol: UDP
      port: 53
