### Controller (running locally)

1. Set env $WATCH_NAMESPACE (default value is "istio-system") and $LEADER_ELECTION_NAMESPACE (default value is "istio-operator")

1. Create the `WATCH_NAMESPACE` and `LEADER_ELECTION_NAMESPACE` if they are not created yet.

```bash
kubectl create ns $WATCH_NAMESPACE --dry-run -o yaml | kubectl apply -f -
kubectl create ns $LEADER_ELECTION_NAMESPACE --dry-run -o yaml | kubectl apply -f -
```

```

TODO. It is possible to add Istio-CNI later, and gradually migrate.

### Install Control plane

This can run in any cluster. A mesh should have at least one cluster should run Pilot or equivalent XDS server,
and it is recommended to have Pilot running in each region and in multiple availability zones for multi cluster.

```bash
iop istio-control istio-discovery $IBASE/istio-control/istio-discovery \
