`istio-system`. The new components will not interfere with existing apps, but can interoperate,
and it is possible to gradually move apps from Istio 1.0/1.1 to the new environments and
across environments ( for example canary -> prod )

Note: there are still some cluster roles that may need to be fixed, most likely cluster permissions
will need to move to the security component.

   * underlying multimap.
   *
   * <p>The returned multimap isn't threadsafe or serializable, even if {@code unfiltered} is.
   *
   * <p>Many of the filtered multimap's methods, such as {@code size()}, iterate across every
   * key/value mapping in the underlying multimap and determine which satisfy the filter. When a
   * live view is <i>not</i> needed, it may be faster to copy the filtered multimap and use the
   * copy.

Donc, dans **OpenAPI**, chaque méthode HTTP est appelée une "opération".

Nous allons donc aussi appeler ces dernières des "**opérations**".


#### Définir un *décorateur d'opération de chemin*

```Python hl_lines="6"

Le `Union` dans `Union[str, None]` permettra à votre éditeur de vous offrir un meilleur support et de détecter les erreurs.

## Validation additionnelle

Nous allons imposer que bien que `q` soit un paramètre optionnel, dès qu'il est fourni, **sa longueur n'excède pas 50 caractères**.

## Importer `Query`

Pour cela, importez d'abord `Query` depuis `fastapi` :

	// ignored.
	if c.cfg.SidecarAnnotation != "" {
		if _, ok := pod.ObjectMeta.Annotations[c.cfg.SidecarAnnotation]; !ok {

	// crashlooping init containers that match our criteria
	for _, container := range pod.Status.InitContainerStatuses {
		// Skip the container if the InitContainerName is not a match and our

Mais malheureusement, rien d'utile n'en résulte :

### Ajouter des types

Modifions une seule ligne de la version précédente.

Nous allons changer seulement cet extrait, les paramètres de la fonction, de :


```Python
    first_name, last_name
```

à :

```Python
    first_name: str, last_name: str
```

C'est tout.
