CRDs in place and not have Istio modify them. In this case, it is necessary to apply CRD files individually.

```bash
kubectl apply -k github.com/istio/installer/base
```

or

```bash
kubectl apply -f base/files
```

### Install Istio-CNI

This is an optional step - CNI must run in a dedicated namespace, it is a 'singleton' and extremely

for deprecation.

[Profiles](https://istio.io/docs/setup/kubernetes/additional-setup/config-profiles/), are provided as a starting point for
an Istio install and can be customized by creating customization overlay files or passing parameters through the
--set flag. For example, to select the minimal profile:

```yaml
# minimal.yaml

apiVersion: install.istio.io/v1alpha1
kind: IstioOperator
spec:
  profile: minimal
```
