- In ambient mode, the CNI plugin does not configure any networking, but is only responsible for synchronously pushing new pod events back up to an ambient watch server which runs as part of the Istio CNI node agent. The ambient server will find the pod netns and configure networking inside that pod via iptables. The ambient server will additionally watch enabled namespaces, and enroll already-started-but-newly-enrolled...
