Phase 10-08: Implement DNS egress NetworkPolicy for staging environment
- Add comprehensive network policies to k8s/staging/network-policy.yaml - Implements default-deny ingress pattern with explicit allow rules - Critical: Add DNS egress rule for CoreDNS resolution (port 53 UDP/TCP) - Policies cover: ingress-nginx→backend, backend→postgres, monitoring scrape - External API egress for backend (HTTP/HTTPS) - CDN egress for frontend (HTTP/HTTPS) - Status: Applied to gravl-staging namespace, verified operational
