# ntfy faces the internet through Envoy, so its pods only reach each
|
|
# other, DNS and the internet: not the LAN (NAS, router), the Kubernetes
|
|
# API or other namespaces.
|
|
# Push notifications go out over the internet.
|
|
# Ingress comes from Envoy and the node itself (kubelet probes; 10.1.7.64
|
|
# is the node's Calico VXLAN address, projectcalico.org/IPv4VXLANTunnelAddr).
|
|
# Same layout as mbgwp/networkpolicy.yaml.
