- watches k8s resource for existing pods, so that pods that have already been started can be moved in or out of the ambient mesh.
- sends UDS events to ztunnel via a socket whenever a pod is enabled for ambient mesh (whether from CNI plugin or node watcher), instructing ztunnel to create the "tube" socket.

To avoid this, the project attempts to minimize additions to the `values.yaml` API where possible.

If the change is a dynamic runtime configuration, it probably belongs in the [MeshConfig API](https://github.com/istio/api/blob/master/mesh/v1alpha1/config.proto).
This allows configuration without re-installing or restarting deployments.

As ztunnel aims to transparently encrypt and route users traffic, we need a mechanism to capture all traffic entering and leaving "mesh" pods.
This is a security critical task: if the ztunnel can be bypassed, authorization policies can be bypassed.

Redirection must meet these requirements:
* All traffic *egressing* a pod in the mesh should be redirected to the node-local ztunnel on port 15001.

stable version in place and gradually migrate apps to the new version.

- More flexibility: the new installer allows multiple 'environments', allowing applications to select
a set of control plane settings and components. While the entire mesh respects the same APIs and config,
apps may target different 'environments' which contain different instances and variants of Istio.

## Introduction

The operator uses the [IstioOperator API](https://github.com/istio/api/blob/master/operator/v1alpha1/operator.proto), which has
three main components:

- [MeshConfig](https://github.com/istio/api/blob/master/mesh/v1alpha1/config.proto) for runtime config consumed directly by Istio
control plane components.
