2) `istio-cni` chart installs the CNI plugin. This should be installed after the `base` chart and prior to `istiod` chart. Need to add `--set pilot.cni.enabled=true` to the `istiod` install to enable its usage.

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

### Overview

- [istio-cni Helm chart](../manifests/charts/istio-cni/templates)
    - `install-cni` daemonset - main function is to install and help the node CNI, but it is also a proper server and interacts with K8S, watching Pods for recovery.
    - `istio-cni-config` configmap with CNI plugin config to add to CNI plugin chained config
