of the conventional `istio-injected: true`. The name of the environment is defined as the namespace
where the corresponding control plane components (config, discovery, auto-injection) are running.
In the examples below, by default this is the `istio-control` namespace. Pod annotations can also
be used to select a different 'environment'.

## Installing

```

This installs the controller into the cluster in the istio-operator namespace. The controller in turns installs
the Istio control plane into the istio-system namespace by default.

### Controller (running locally)

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