# CiliumNetworkPolicy for kube-apiserver access.
|
||
|
|
#
|
||
|
|
# Standard K8s NetworkPolicy ipBlock rules don't work for the API server
|
||
|
|
# under Cilium — the except clause on 192.168.1.0/24 blocks the post-DNAT
|
||
|
|
# destination even when a separate rule re-allows a /32 or subnet.
|
||
|
|
#
|
||
|
|
# Cilium's native `kube-apiserver` entity resolves this correctly: it
|
||
|
|
# tracks the API server endpoints regardless of ClusterIP vs node-IP
|
||
|
|
# routing, so the policy stays valid across node changes and NAT paths.
