## Everything is Optional

Each component in the new installer is optional. Users can install the component defined in the new installer,
use the equivalent component in `istio-system`, configured with the official installer, or use a different
version or implementation.

For example, you may use your own Prometheus and Grafana installs, or you may use a specialized/custom

	resultCreateCNIConfigFailure  = "CREATE_CNI_CONFIG_FAILURE"

	cniInstalls = monitoring.NewSum(
		"istio_cni_installs_total",
		"Total number of CNI plugins installed by the Istio CNI installer",
	)

	installReady = monitoring.NewGauge(
		"istio_cni_install_ready",
		"Whether the CNI plugin installation is ready or not",
	)

				CNIBinTargetDirs: []string{cniBinDir},
			}

			isReady := &atomic.Value{}
			isReady.Store(false)
			installer := NewInstaller(cfg, isReady)
			installer.cniConfigFilepath = cniConfigFilePath
			installer.kubeconfigFilepath = kubeConfigFilePath
			err := installer.Cleanup()
			if (c.expectedFailure && err == nil) || (!c.expectedFailure && err != nil) {

Install the controller manifest:

```bash
istioctl operator init --hub docker.io/<your-account> --tag latest
kubectl create ns istio-system
kubectl apply -f operator/samples/default-install.yaml
```

This installs the controller into the cluster in the istio-operator namespace. The controller in turns installs

          # reason for closed the issue default value is not_planned
          close-issue-reason: completed
          # List of labels to remove when issues/PRs unstale. 
          labels-to-remove-when-unstale: "stat:contribution welcome,stat:good first issue"
          any-of-labels: "stat:contribution welcome,stat:good first issue"

Après avoir activé l'environnement comme décrit ci-dessus, installez `flit` :

<div class="termy">

```console
$ pip install flit

---> 100%
```

</div>

Réactivez maintenant l'environnement pour vous assurer que vous utilisez le "flit" que vous venez d'installer (et non un environnement global).

Et maintenant, utilisez `flit` pour installer les dépendances de développement :
