3) `istio-control/istio-discovery` chart installs a revision of istiod.

```console
 helm install -n istio-system istiod manifests/charts/istio-control/istio-discovery --set profile=openshift
```

4) `gateways` charts install a load balancer with `ingress` and `egress`.

Ingress secrets and access should be separated from the control plane.
