**FastAPI** provides the same `starlette.staticfiles` as `fastapi.staticfiles` just as a convenience for you, the developer. But it actually comes directly from Starlette.

### What is "Mounting"

"Mounting" means adding a complete "independent" application in a specific path, that then takes care of handling all the sub-paths.

If you need to have two independent FastAPI applications, with their own independent OpenAPI and their own docs UIs, you can have a main app and "mount" one (or more) sub-application(s).

## Mounting a **FastAPI** application

"Mounting" means adding a completely "independent" application in a specific path, that then takes care of handling everything under that path, with the _path operations_ declared in that sub-application.

```

!!! note "技术细节"
    你也可以用 `from starlette.staticfiles import StaticFiles`。

    **FastAPI** 提供了和 `starlette.staticfiles` 相同的 `fastapi.staticfiles` ，只是为了方便你，开发者。但它确实来自Starlette。

### 什么是"挂载"(Mounting)

"挂载" 表示在特定路径添加一个完全"独立的"应用，然后负责处理所有子路径。

这与使用`APIRouter`不同，因为安装的应用程序是完全独立的。OpenAPI和来自你主应用的文档不会包含已挂载应用的任何东西等等。

你可以在**高级用户指南**中了解更多。

## 细节

اگر نیاز دارید که دو برنامه مستقل FastAPI، با OpenAPI مستقل و رابط‌های کاربری اسناد خود داشته باشید، می‌توانید یک برنامه
اصلی داشته باشید و یک (یا چند) زیر برنامه را به آن متصل کنید.

## اتصال (mount) به یک برنامه **FastAPI**

کلمه "Mounting" به معنای افزودن یک برنامه کاملاً مستقل در یک مسیر خاص است، که پس از آن مدیریت همه چیز در آن مسیر، با path operations (عملیات های مسیر) اعلام شده در آن زیر برنامه می باشد.

  // method), and that the Kubernetes attach detach controller should call
  // the attach volume interface which checks the volumeattachment status
  // and waits until the volume is attached before proceeding to mounting.
  // The CSI external-attacher coordinates with CSI volume driver and updates
  // the volumeattachment status when the attach operation is complete.
  // If the CSIDriverRegistry feature gate is enabled and the value is

The `root_path` is a mechanism provided by the ASGI specification (that FastAPI is built on, through Starlette).

The `root_path` is used to handle these specific cases.

And it's also used internally when mounting sub-applications.

  * Support for ELBs with complex configurations: better subnet selection with
multiple subnets, and internal ELBs
  * Support for VPCs with private dns names
  * Multiple fixes to EBS volume mounting code for robustness, and to support
mounting the full number of AWS recommended volumes.
  * Multiple fixes to avoid hitting AWS rate limits, and to throttle if we do
  * Support for the EC2 Container Registry (currently in us-east-1 only)

  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).

* Google Compute Engine PD Detach fails if node no longer exists ([29358](https://github.com/kubernetes/kubernetes/issues/29358))
* Mounting (only 'default-token') volume takes a long time when creating a batch of pods  (parallelization issue) ([28616](https://github.com/kubernetes/kubernetes/issues/28616))
