### Créer `Settings` une seule fois avec `lru_cache` { #creating-the-settings-only-once-with-lru-cache }

Lire un fichier depuis le disque est normalement une opération coûteuse (lente), vous voudrez donc probablement le faire une seule fois puis réutiliser le même objet de paramètres, au lieu de le lire à chaque requête.

  For more information, see [#57198](https://github.com/kubernetes/kubernetes/issues/57198).

*   Mutating and validating webhook configurations are continuously polled by the API server (once per second). This issue will be fixed in a future release.

  For more information, see [#56357](https://github.com/kubernetes/kubernetes/issues/56357).

Zaten bir **FastAPI Cloud** hesabınız varsa (bekleme listesinden sizi davet ettiysek 😉), uygulamanızı tek komutla deploy edebilirsiniz.

Deploy etmeden önce giriş yaptığınızdan emin olun:

<div class="termy">

```console
$ fastapi login

You are logged in to FastAPI Cloud 🚀
```

</div>

Ardından uygulamanızı deploy edin:

				if took > maxDurationSecondsForLog {
					// Log if we took a lot of time to load.
					logger.Info("IAM refresh took (duration: %.2fs)", took)
				}
			}

			// Run purge routines once in each hour.
			if refreshStart.Hour() != lastPurgeHour {
				lastPurgeHour = refreshStart.Hour()
				// Poll and remove accounts for those users who were removed
				// from LDAP/OpenID.

- api-machinery utility functions `SetTransportDefaults` and `DialerFor` once again respect custom Dial functions set on transports ([#65547](https://github.com/kubernetes/kubernetes/pull/65547), [@liggitt](https://github.com/liggitt))

Aqui definimos a configuração `env_file` dentro da sua classe `Settings` do Pydantic e definimos o valor como o nome do arquivo dotenv que queremos usar.

### Criando o `Settings` apenas uma vez com `lru_cache` { #creating-the-settings-only-once-with-lru-cache }

Ler um arquivo do disco normalmente é uma operação custosa (lenta), então você provavelmente vai querer fazer isso apenas uma vez e depois reutilizar o mesmo objeto de configurações, em vez de lê-lo a cada requisição.

Kubernetes components that accepted X.509 client certificate authentication now read the user UID from a certificate subject name RDN with object ID `1.3.6.1.4.1.57683.2`. An RDN with this object ID had to contain a string value and appear no more than once in the certificate subject. Reading the user UID from this RDN could be disabled by setting the beta feature gate `AllowParsingUserUIDFromCertAuth` to `false`(until the feature gate graduated to GA).

- A new `pod_status_sync_duration_seconds` histogram is reported at alpha metrics stability that estimates how long the Kubelet takes to write a pod status change once it is detected.
