Führen Sie nun `uvicorn` aus, indem Sie das Modul `app.main` und die Variable `app` verwenden:

<div class="termy">

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

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

message CSIVolumeSource {
  // driver is the name of the CSI driver that handles this volume.
  // Consult with your admin for the correct name as registered in the cluster.
  optional string driver = 1;

  // readOnly specifies a read-only configuration for the volume.
  // Defaults to false (read/write).

```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
```

	}
}

// The ConsoleLogHandler handler sends console logs to the connected HTTP client.
func (a adminAPIHandlers) ConsoleLogHandler(w http.ResponseWriter, r *http.Request) {
	ctx := r.Context()
	objectAPI, _ := validateAdminReq(ctx, w, r, policy.ConsoleLogAdminAction)
	if objectAPI == nil {
		return
	}
	node := r.Form.Get("node")
	// limit buffered console entries if client requested it.
