### Action Required

* [kubelet] Allow opting out of automatic cloud provider detection in kubelet. By default kubelet will auto-detect cloud providers ([#28258](https://github.com/kubernetes/kubernetes/pull/28258), [@vishh](https://github.com/vishh))

        return;
      }
      // First, check whether var -> arg forms a cycle
      for (Type t = arg; t != null; t = mappings.get(TypeVariableKey.forLookup(t))) {
        if (var.equalsType(t)) {
          // cycle detected, remove the entire cycle from the mapping so that
          // each type variable resolves deterministically to itself.
          // Otherwise, an F -> T cycle will end up resolving both F and T

* Um "Init Container" no Kubernetes que roda antes do seu app container
* Um script bash que roda os passos anteriores e então inicia seu aplicativo
    * Você ainda precisaria de uma maneira de iniciar/reiniciar *aquele* script bash, detectar erros, etc.

/// tip | "Dica"

Darei exemplos mais concretos de como fazer isso com contêineres em um capítulo futuro: [FastAPI em contêineres - Docker](docker.md){.internal-link target=_blank}.

///

/// note

FastAPI will know that the value of `q` is not required because of the default value `= None`.

The `Union` in `Union[str, None]` will allow your editor to give you better support and detect errors.

///

## Additional validation

We are going to enforce that even though `q` is optional, whenever it is provided, **its length doesn't exceed 50 characters**.

### Import `Query` and `Annotated`

* <a href="https://jinja.palletsprojects.com" target="_blank"><code>jinja2</code></a> - Requerido si quieres usar la configuración por defecto de templates.
