## Changelog since v1.18.13

## Changes by Kind

### Feature

- Add a new flag to set priority for the kubelet on Windows nodes so that workloads cannot overwhelm the node there by disrupting kubelet process. ([#96158](https://github.com/kubernetes/kubernetes/pull/96158), [@ravisantoshgudimetla](https://github.com/ravisantoshgudimetla)) [SIG Node]

### Bug or Regression

Multi-arch support (EXPERIMENTAL):
  - kubeadm now adds support for docker “schema 2” manifest lists. This is preliminary part of the process of making kubeadm based k8s deployments to support multiple architectures.
Deprecating features:
  - The Alpha feature-gates HighAvailability, SelfHosting, CertsInSecrets are now deprecated, and will be removed in k8s v1.13.0.

The `string()` method on response body is convenient and efficient for small documents. But if the response body is large (greater than 1 MiB), avoid `string()` because it will load the entire document into memory. In that case, prefer to process the body as a stream.

### 每个容器一个进程 { #one-process-per-container }

在这种场景下，你大概率希望**每个容器只有一个（Uvicorn）进程**，因为你已经在集群层面处理了复制。

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 }

* Return apiserver panics as 500 errors instead terminating the apiserver process. ([#68001](https://github.com/kubernetes/kubernetes/pull/68001), [@sttts](https://github.com/sttts))

([#44744](https://github.com/kubernetes/kubernetes/pull/44744), [@yguo0905](https://github.com/yguo0905))

  * Kubernetes now shares a single PID namespace among all containers in a pod when running with docker >= 1.13.1. This means processes can now signal processes in other containers in a pod, but it also means that the `kubectl exec {pod} kill 1` pattern will cause the Pod to be restarted rather than a single container. ([#45236](https://github.com/kubernetes/kubernetes/pull/45236), [@verb](...

Starlette 是一個輕量的 <dfn title="用於構建非同步 Python 網頁應用的新標準">ASGI</dfn> 框架／工具集，非常適合用來建構高效能的 asyncio 服務。

它非常簡單直觀。設計上易於擴充，且元件化。

它具備：

* 令人印象深刻的效能。
* WebSocket 支援。
* 行程內（in-process）背景任務。
* 啟動與關閉事件。
* 建立在 HTTPX 上的測試用戶端。
* CORS、GZip、靜態檔案、串流回應。
* Session 與 Cookie 支援。
* 100% 測試涵蓋率。
* 100% 型別註解的程式碼庫。
* 幾乎沒有硬性相依。

Starlette 目前是測試中最快的 Python 框架。僅次於 Uvicorn（它不是框架，而是伺服器）。

for purposes such as debugging, similar to how `kubectl exec` runs a process in an existing container. Also like `kubectl exec`, no resources are reserved for ephemeral containers and they are not restarted when they exit. Note that container namespace targeting is not yet implemented, so [process namespace sharing](https://kubernetes.io/docs/tasks/configure-pod-container/share-process-namespace/) must be enabled to view process from other containers in the pod.
