Alternative is to use CephFS CSI driver (https://github.com/ceph/ceph-csi/) in your Kubernetes Cluster. A re-deployment of your application is required to use the new driver if you were using `kubernetes.io/cephfs` volume plugin before upgrading...

- Add NeedResize function to kubernetes/mount-utils, user can call this function to determine if fs need to be resized ([#101253](https://github.com/kubernetes/kubernetes/pull/101253), [@AndyXiangLi](https://github.com/AndyXiangLi)) [SIG Storage]

Esse, é claro, não é o ideal e você não o usaria para produção.

Na produção, você teria uma das opções acima.

Mas é a maneira mais simples de focar no lado do servidor de WebSockets e ter um exemplo funcional:

{* ../../docs_src/websockets/tutorial001_py39.py hl[2,6:38,41:43] *}

## Crie um `websocket` { #create-a-websocket }

Em sua aplicação **FastAPI**, crie um `websocket`:

Esto, por supuesto, no es lo ideal y no lo usarías para producción.

En producción tendrías una de las opciones anteriores.
