standard storage class. ## If the PV uses a different storage class, specify that here. storageClass: "" VolumeName: "" accessMode: ReadWriteOnce size: 500Gi ## If subPath is set mount a sub folder of a volume instead of the root of the volume. ## This is especially handy for volume plugins that don't natively support sub mounting (like glusterfs). ## subPath: "" ## Expose the MinIO service to be accessed from outside the cluster (LoadBalancer service). ## or access it from within the cluster (ClusterIP...

To do that, we declare a method `__call__`:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[12] *}

In this case, this `__call__` is what **FastAPI** will use to check for additional parameters and sub-dependencies, and this is what will be called to pass a value to the parameter in your *path operation function* later.

## Parameterize the instance { #parameterize-the-instance }

- MinIO distributed mode requires **fresh directories**. If required, the drives can be shared with other applications. You can do this by using a sub-directory exclusive to MinIO. For example, if you have mounted your volume under `/export`, pass `/export/data` as arguments to MinIO server.

### Create the `Settings` object { #create-the-settings-object }

Import `BaseSettings` from Pydantic and create a sub-class, very much like with a Pydantic model.

The same way as with Pydantic models, you declare class attributes with type annotations, and possibly default values.

## 子应用

`FastAPI` é na verdade uma sub-classe do `Starlette`. Então, se você já conhece ou usa Starlette, a maioria das funcionalidades se comportará da mesma forma.

Para hacer eso, declaramos un método `__call__`:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[12] *}

En este caso, este `__call__` es lo que **FastAPI** usará para comprobar parámetros adicionales y sub-dependencias, y es lo que llamará para pasar un valor al parámetro en tu *path operation function* más adelante.

## Parametrizar la instance { #parameterize-the-instance }

     * For example, if the {@code module-info.class} entry of a <abbr>JAR</abbr> file exists only in the
     * {@code META-INF/versions/17/} sub-directory, then the default location of that dependency will be
     * the module-path only if the {@code --release} option is equal or greater than 17.
     *
