因此，在这种情况下，你**不会**希望拥有像 Gunicorn 和 Uvicorn worker一样的进程管理器，或者 Uvicorn 使用自己的 Uvicorn worker。 你可能希望每个容器（但可能有多个容器）只有一个**单独的 Uvicorn 进程**。

在容器内拥有另一个进程管理器（就像使用 Gunicorn 或 Uvicorn 管理 Uvicorn 工作线程一样）只会增加**不必要的复杂性**，而你很可能已经在集群系统中处理这些复杂性了。

### 具有多个进程的容器

当然，在某些**特殊情况**，你可能希望拥有 **一个容器**，其中包含 **Gunicorn 进程管理器**，并在其中启动多个 **Uvicorn worker进程**。

Но часто Вам может понадобиться несколько одновременно работающих одинаковых процессов.

Aqui estão algumas combinações e estratégias possíveis:

* **Uvicorn** com `--workers`
    * Um **gerenciador de processos** Uvicorn escutaria no **IP** e na **porta** e iniciaria **vários processos de trabalho Uvicorn**.
* **Kubernetes** e outros **sistemas de contêineres** distribuídos

        decides which workers to read from. If `"ANY"`, TF workers read from any
        tf.data service workers. If `"LOCAL"`, TF workers will only read from
        local in-processs tf.data service workers. `"AUTO"` works well for most
        cases, while users can specify other targets. For example, `"LOCAL"`
        would help avoid RPCs and data copy if every TF worker colocates with a

In diesem Fall möchten Sie also **nicht** einen Prozessmanager wie Gunicorn mit Uvicorn-Workern oder Uvicorn mit seinen eigenen Uvicorn-Workern haben. Sie möchten nur einen **einzelnen Uvicorn-Prozess** pro Container haben (wahrscheinlich aber mehrere Container).
