Parmi les concepts importants, on trouve :

* Sécurité - HTTPS
* Exécuter au démarrage
* Redémarrages
* Réplication (le nombre de processus en cours d'exécution)
* Mémoire
* Étapes préalables avant de démarrer

Nous allons voir comment ils affectent les **déploiements**.

Estos proxies podrían manejar certificados HTTPS y otras cosas.

## Headers reenviados por el Proxy { #proxy-forwarded-headers }

Un **proxy** delante de tu aplicación normalmente establecería algunos headers sobre la marcha antes de enviar los requests a tu **server** para que el servidor sepa que el request fue **reenviado** por el proxy, informándole la URL original (pública), incluyendo el dominio, que está usando HTTPS, etc.

* `GET` : pour lire des données.
* `PUT` : pour mettre à jour des données.
* `DELETE` : pour supprimer des données.

Donc, dans OpenAPI, chacune des méthodes HTTP est appelée une « opération ».

Nous allons donc aussi les appeler « opérations ».

Ao validar os dados com o Pydantic nós podemos garantir que temos, por exemplo, exatamente uma `list` de `str` com os escopos e uma `str` com o `username`.

No lugar de, por exemplo, um `dict`, ou alguma outra coisa, que poderia quebrar a aplicação em algum lugar mais tarde, tornando isso um risco de segurança.

Nós também verificamos que nós temos um usuário com o "*username*", e caso contrário, nós levantamos a mesma exceção que criamos anteriormente.

    * This more closely aligns rest client as a generic RESTful client, while preserving the special Kube API extended error handling for the `Get` and `Into` methods (which most Kube clients use).

  Bump NodeProblemDetector version to v0.8.0 to reduce forced NodeStatus updates frequency to 5 minutes. ([#84007](https://github.com/kubernetes/kubernetes/pull/84007), [@wojtek-t](https://github.com/wojtek-t))
- The topology manager aligns resources for pods of all QoS classes with respect to NUMA locality, not just Guaranteed QoS pods. ([#83492](https://github.com/kubernetes/kubernetes/pull/83492), [@ConnorDoyle](https://github.com/ConnorDoyle))

- `kubeadm`: will now allow deploying a kubelet that is 3 versions older than the version of `kubeadm` (N-3). This aligns with the recent change made by SIG Architecture that extends the support skew between the control plane and kubelets. Tolerate this new kubelet skew for the commands `init`, `join` and `upgrade`. Note that if the `kubeadm` user applies a control plane...

- XFS-filesystems are now force-formatted (option `-f`) in order to avoid problems being formatted due to detection of magic super-blocks. This aligns with the behaviour of formatting of ext3/4 filesystems. ([#104923](https://github.com/kubernetes/kubernetes/pull/104923), [@davidkarlsen](https://github.com/davidkarlsen))
