Agora, execute `uvicorn`, usando o módulo `app.main` e a variável `app`:

<div class="termy">

```console
$ uvicorn app.main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

		if err != nil {
			peersLogIf(context.Background(), fmt.Errorf("Failed to reload remote tier config %s", err))
		}
	}()

	return
}

// ConsoleLogHandler sends console logs of this node back to peer rest client
func (s *peerRESTServer) ConsoleLogHandler(ctx context.Context, params *grid.MSS, out chan<- *grid.Bytes) *grid.RemoteErr {
	mask, err := strconv.Atoi(params.Get(peerRESTLogMask))

该文件`__init__.py`只是一个空文件，但它告诉 Python `sql_app` 是一个包。

现在让我们看看每个文件/模块的作用。

## 安装 SQLAlchemy

首先你需要安装`SQLAlchemy`:

<div class="termy">

```console
$ pip install sqlalchemy

---> 100%
```

</div>

## 创建 SQLAlchemy 部件

让我们转到文件`sql_app/database.py`。

### 导入 SQLAlchemy 部件

```Python hl_lines="1-3"

* the contents your program gave to the system to be written to disk
* a remote API operation
* a database operation to finish
* a database query to return the results
* etc.

As the execution time is consumed mostly by waiting for <abbr title="Input and Output">I/O</abbr> operations, they call them "I/O bound" operations.

// - such an object exists, but the capacity is unset
// - such an object exists, but the capacity is zero
//
// The producer of these objects can decide which approach is more suitable.
//
// They are consumed by the kube-scheduler when a CSI driver opts into
// capacity-aware scheduling with CSIDriverSpec.StorageCapacity. The scheduler
// compares the MaximumVolumeSize against the requested size of pending volumes

<div class="termy">

```console
$ docker build -t myimage .

---> 100%
```

</div>

/// tip

末尾の `.` に注目してほしいです。これは `./` と同じ意味です。 これはDockerにコンテナイメージのビルドに使用するディレクトリを指示します。

この場合、同じカレント・ディレクトリ(`.`)です。

### Dockerコンテナの起動する

* イメージに基づいてコンテナを実行します：

<div class="termy">

```console
$ docker run -d --name mycontainer -p 80:80 myimage
```

type eofReader struct {
	buf []byte
}

func (r *eofReader) Read(p []byte) (int, error) {
	read := copy(p, r.buf)
	r.buf = r.buf[read:]

	switch read {
	case 0, len(r.buf):
		// As allowed in the documentation, this will return io.EOF
		// in the same call that consumes the last of the data.
		// https://godoc.org/io#Reader

	b.lastByte = -1
	b.lastRuneSize = -1
	return nil
}

// ReadRune reads a single UTF-8 encoded Unicode character and returns the
// rune and its size in bytes. If the encoded rune is invalid, it consumes one byte
// and returns unicode.ReplacementChar (U+FFFD) with a size of 1.
func (b *Reader) ReadRune() (r rune, size int, err error) {
