Verwenden Sie ihn auf die gleiche Weise wie die Klasse `FastAPI`:

```Python hl_lines="6  11  16" title="app/routers/users.py"
{!../../docs_src/bigger_applications/app/routers/users.py!}
```

Sie können sich `APIRouter` als eine „Mini-`FastAPI`“-Klasse vorstellen.

Alle die gleichen Optionen werden unterstützt.

Alle die gleichen `parameters`, `responses`, `dependencies`, `tags`, usw.

    private final SecretKey encryptionKey;
    
    public void saveEncrypted(HandleInfo handle, Path file) throws Exception {
        Cipher cipher = Cipher.getInstance("AES/GCM/NoPadding");
        cipher.init(Cipher.ENCRYPT_MODE, encryptionKey);
        
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        try (CipherOutputStream cos = new CipherOutputStream(baos, cipher);

Es hängt **stark** davon ab, wie Sie **Ihr System bereitstellen**, und hängt wahrscheinlich mit der Art und Weise zusammen, wie Sie Programme starten, Neustarts durchführen, usw.

Hier sind einige mögliche Ideen:

* Ein „Init-Container“ in Kubernetes, der vor Ihrem Anwendungs-Container ausgeführt wird
* Ein Bash-Skript, das die Vorab-Schritte ausführt und dann Ihre Anwendung startet

Puedes pensar en `APIRouter` como una clase "mini `FastAPI`".

Se soportan todas las mismas opciones.

Todos los mismos `parameters`, `responses`, `dependencies`, `tags`, etc.

kubeadm: Promoted the feature gate `ControlPlaneKubeletLocalMode` to Beta. By default, kubeadm will use the local kube-apiserver endpoint for the kubelet when creating a cluster with `kubeadm init` or when joining control plane nodes with `kubeadm join`. Enabling the feature gate also affects the `kubeadm init phase kubeconfig kubelet` phase, where the flag `--control-plane-endpoint` no longer affects the generated kubeconfig `Server` field, but the flag `--apiserver-advertise-address` can now be used...
