Istio's helm charts come with a common `openshift` profile that can be used during installation.

The installation process using the Helm charts is as follows:

1) `base` chart creates cluster-wide CRDs, cluster bindings and cluster resources. It is possible to change the namespace from `istio-system` but it is not recommended.

```console
helm install istio-base -n istio-system manifests/charts/base --set profile=openshift
```

  // must be specified.
  //
  // The `host` should not refer to a service running in the cluster; use
  // the `service` field instead. The host might be resolved via external
  // DNS in some apiservers (e.g., `kube-apiserver` cannot resolve
  // in-cluster DNS as that would be a layering violation). `host` may
  // also be an IP address.
