## Reference

### Design details

Broadly, `istio-cni` accomplishes ambient redirection by instructing ztunnel to set up sockets within the application pod network namespace, where:

- one end of the socket is in the application pod
- and the other end is in ztunnel's pod

and setting up iptables rules to funnel traffic thru that socket "tube" to ztunnel and back.

```bash
HUB=docker.io/<your-account> TAG=latest make docker.operator
```

This builds the controller binary and docker file, and pushes the image to the specified hub with the `latest` tag.
Once the images are pushed, configure kubectl to point to your cluster and install the controller.

Install the controller manifest:

```bash
istioctl operator init --hub docker.io/<your-account> --tag latest
