Hints: networkpolicy-block

Hint 1

Traffic between pods is being blocked. Check for NetworkPolicies: - kubectl get networkpolicy -n grokdevops

Hint 2

A NetworkPolicy is restricting traffic. Check its rules: - kubectl describe networkpolicy -n grokdevops - Is there a default-deny policy? What ingress/egress rules exist?

Hint 3

Check if pod labels match the policy's allowed selectors: - kubectl get pods -n grokdevops --show-labels - Compare with the NetworkPolicy's spec.ingress[].from[].podSelector - Also check if egress to DNS (port 53) is allowed

Hint 4

Fix: either remove the restrictive policy, add the correct labels to allow traffic, or add an egress rule for DNS. The chaos script toggle_networkpolicy.sh has a built-in restore.
