## Was ist ein Container?

     * 这里我们传递了 Gunicorn 可以导入和使用的类：

         ```Python
         import uvicorn.workers.UvicornWorker
         ```

* `--bind`：这告诉 Gunicorn 要监听的 IP 和端口，使用冒号 (`:`) 分隔 IP 和端口。
     * 如果您直接运行 Uvicorn，则可以使用`--host 0.0.0.0`和`--port 80`，而不是`--bind 0.0.0.0:80`（Gunicorn 选项）。


在输出中，您可以看到它显示了每个进程的 **PID**（进程 ID）（它只是一个数字）。

你可以看到：

* Gunicorn **进程管理器** 以 PID `19499` 开头（在您的情况下，它将是一个不同的数字）。
* 然后它开始`Listening at: http://0.0.0.0:80`。
