有一个官方 Docker 镜像，其中包含与 Uvicorn worker一起运行的 Gunicorn，如上一章所述：[服务器工作线程 - Gunicorn 与 Uvicorn](server-workers.md){.internal-link target=_blank}。

该镜像主要在上述情况下有用：[具有多个进程和特殊情况的容器](#containers-with-multiple-processes-and-special-cases)。

### 多进程 - 一个例子

在此示例中，有一个 **Manager Process** 启动并控制两个 **Worker Processes**。

该管理器进程可能是监听 IP 中的 **端口** 的进程。 它将所有通信传输到工作进程。

这些工作进程将是运行您的应用程序的进程，它们将执行主要计算以接收 **请求** 并返回 **响应**，并且它们将加载您放入 RAM 中的变量中的任何内容。
