multiple values, like Guava's [Multimap](https://guava.dev/releases/23.0/api/docs/com/google/common/collect/Multimap.html). For example, it's legal and common for an HTTP response to supply multiple `Vary` headers. OkHttp's APIs attempt to make both cases comfortable.

When writing request headers, use `header(name, value)` to set the only occurrence of `name` to `value`. If there are existing values, they will be removed before the new value is added. Use `addHeader(name, value)` to add a...

因此，这种情况下你**不希望**在容器内再启多个 workers（例如通过 `--workers` 命令行选项）。你会希望每个容器仅有一个**单独的 Uvicorn 进程**（但可能会有多个容器）。

在容器内再放一个进程管理器（就像启多个 workers 一样）只会引入**不必要的复杂性**，而这些你很可能已经在集群系统中处理了。

### 具有多个进程和特殊情况的容器 { #containers-with-multiple-processes-and-special-cases }

当然，也有一些**特殊情况**，你可能希望让**一个容器**里运行多个 **Uvicorn worker 进程**。

在这些情况下，你可以使用 `--workers` 命令行选项来设置要运行的 worker 数量：

- In some cases, a Flex volume resize may leave a PVC with erroneous Resizing condition even after volume has been successfully expanded. Users may choose to delete the condition, but it is not required. ([#71470](https://github.com/kubernetes/kubernetes/issues/71470))

  - `requests.deviceclass.resource.k8s.io/<deviceclass>` is charged based on the worst-case number of devices requested.
