gate UnversionedKubeletConfigMap. When this feature is enabled kubeadm will start using a new naming format for the ConfigMap where it stores the KubeletConfiguration structure. The old format included the Kubernetes version - "kube-system/kubelet-config-1.22", while the new format does not - "kube-system/kubelet-config". A similar formatting change is done for the related RBAC rules. The old format is now DEPRECATED and will be removed after the feature graduates to GA. When writing the ConfigMap...

Você o coloca em cima de uma função. Como um chapéu decorativo (acho que é daí que vem o termo).

Um "decorador" pega a função abaixo e faz algo com ela.

Em nosso caso, este decorador informa ao **FastAPI** que a função abaixo corresponde a **rota** `/` com uma **operação** `get`.

É o "**decorador de rota**".

Você também pode usar as outras operações:

* `@app.post()`
* `@app.put()`
