1. By running as a node-level daemonset that:

- listens for these UDS events from the CNI plugin (which fire when new pods are spawned in an ambient-enabled namespace), and adds those pods to the ambient mesh.
- watches k8s resource for existing pods, so that pods that have already been started can be moved in or out of the ambient mesh.
