### Wstrzykiwanie Zależności

FastAPI zawiera niezwykle łatwy w użyciu, ale niezwykle potężny system <abbr title='Po angielsku: Dependency Injection. Znane również jako "components", "resources", "services", "providers"'><strong>Wstrzykiwania Zależności</strong></abbr>.

* Nawet zależności mogą mieć zależności, tworząc hierarchię lub **"graf" zależności**.

- If `PreBindPreFlight` returned `Skip`, the scheduler didn't run the plugin at `PreBind`.
  If any `PreBindPreFlight` returned `Success`, the scheduler put NominatedNodeName to the pod 
  so that other components (such as the cluster autoscaler) could notice the pod was going to be bound to the node. ([#133021](https://github.com/kubernetes/kubernetes/pull/133021), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling and Testing]

### Dependency Injection

FastAPI bao gồm một hệ thống <abbr title='cũng biết đến như là "components", "resources", "services", "providers"'><strong>Dependency Injection</strong></abbr> vô cùng dễ sử dụng nhưng vô cùng mạnh mẽ.

- Added to `MutableFeatureGate` the ability to override the default setting of feature gates, to allow default-enabling a feature on a component-by-component basis instead of for all affected components simultaneously.

### Deploy a more secure control plane with kubeadm

This is available with Pydantic version 2 or above. 😎

/// tip

If you need to do any type of validation that requires communicating with any **external component**, like a database or another API, you should instead use **FastAPI Dependencies**, you will learn about them later.

These custom validators are for things that can be checked with **only** the **same data** provided in the request.

    * Esta extensión SNI permite que un solo servidor (con una **sola dirección IP**) tenga **varios certificados HTTPS** y sirva **múltiples dominios/aplicaciones HTTPS**.
    * Para que esto funcione, un componente (programa) **único** que se ejecute en el servidor, escuchando en la **dirección IP pública**, debe tener **todos los certificados HTTPS** en el servidor.

flag --port=0 to kube-controller-manager and kube-scheduler manifests to disable insecure serving. Without this flag the components by default serve (e.g. /metrics) insecurely on the default node interface (controlled by --address). Users that wish to override this behavior and enable insecure serving can pass a custom --port=X via kubeadm's "extraArgs" mechanic for these components.
