- for 'internal load balancer' you should deploy a separate gateway, in a different
namespace.

All ingress gateway have a "app:ingressgateway" label, used to identify it as an
ingress, and an "istio: ingressgateway$SUFFIX" label of Gateway selection.

The Gateways use "istio: ingressgateway$SUFFIX" selectors.


# Multiple gateway versions



# Using different pilot versions

## Installing the Chart

To install the chart with the release name `istio-ingressgateway`:

```console
helm install istio-ingressgateway istio/gateway
```

## Uninstalling the Chart

To uninstall/delete the `istio-ingressgateway` deployment:

```console
helm delete istio-ingressgateway
```

## Configuration

To view support configuration options and documentation, run:

10.244.0.176:8080                                HEALTHY                  outbound|80||istio-ingressgateway.istio-system.svc.cluster.local
10.244.0.176:8443                                HEALTHY                  outbound|443||istio-ingressgateway.istio-system.svc.cluster.local
10.244.0.176:15021                               HEALTHY                  outbound|15021||istio-ingressgateway.istio-system.svc.cluster.local

4. Modify the DNS server to add the A record of the new namespace
5. Check traffic
6. Delete the A record corresponding to the gateway in istio-system
7. Upgrade istio-system, disabling the ingressgateway
8. Delete the domain TLS certs from istio-system.

#### Install from file path

kind: IstioOperator
metadata:
  namespace: istio-operator
spec:
  components:
    ingressGateways:
    - name: istio-ingressgateway
      enabled: true
      namespace: istio-gateways
```

the resulting namespaces will be:

| Component | Namespace |
| --------- | :-------- |
ingressGateways | istio-gateways
