- 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.

This effectively behaves like ztunnel is an in-pod sidecar, without actually requiring the injection of ztunnel as a sidecar into the pod manifest, or mutatating the application pod in any way.

workloads can talk with each other and obey the Istio configuration resources, but each environment
can use different Istio versions and different configuration defaults.

`istioctl kube-inject` or the automatic sidecar injector are used to select the environment.
In the case of the sidecar injector, the namespace label `istio-env: <NAME_OF_ENV>` is used instead

doubt re-run istioctl kube-inject on deployments to get the most up-to-date changes.

It's best to do kube-inject when the resource is initially created.
