The ateom container uses Drop: ALL with an explicit Add list, so being UID 0 does not grant privileged-port binding — NET_BIND_SERVICE must be explicitly added. Without it, atunnel's listener on port 443 gets bind: permission denied on bare-metal nodes. GKE masked the bug via platform-level defaults that do not reliably propagate into every pod netns. Tested on a bare-metal kubeadm cluster (RHEL 10, CRI-O 1.36).
