With this in mind, Ztunnel supports two xDS resources: `Address` and `Authorization`.

### Address Type

The primary configuration consumed by Ztunnel is the [`Address` resource](../../pkg/workloadapi/workload.proto).
As the name suggests, an `Address` represents a particular IP Address.
This can be a `Service` or a `Workload`.

The address type has the following goals:

    port: {{ $val.Port }}
    protocol: TCP
    appProtocol: {{ $val.AppProtocol }}
  {{- end }}
  selector:
    "{{.GatewayNameLabel}}": "{{.Name}}"
  {{- if and (.Spec.Addresses) (eq .ServiceType "LoadBalancer") }}
  loadBalancerIP: {{ (index .Spec.Addresses 0).Value | quote}}
  {{- end }}
  type: {{ .ServiceType | quote }}

}

type ZtunnelService struct {
	Name         string         `json:"name"`
	Namespace    string         `json:"namespace"`
	Hostname     string         `json:"hostname"`
	Addresses    []string       `json:"vips"`
	Ports        map[string]int `json:"ports"`
	LoadBalancer *LoadBalancer  `json:"loadBalancer"`
	Waypoint     *Waypoint      `json:"waypoint"`
}

By default it will listen on the IP address `127.0.0.1`, which is the IP for your machine to communicate with itself alone (`localhost`).

## `fastapi run`

When you run `fastapi run`, it will run on production mode by default.

It will have **auto-reload disabled** by default.
