From ca83efe82829541add0ef6cefa68f2089ff61376 Mon Sep 17 00:00:00 2001 From: Clawd Agent Date: Sun, 8 Mar 2026 07:00:07 +0100 Subject: [PATCH] Phase 10-08: Implement DNS egress NetworkPolicy for staging environment MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - 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) -
