- Kubeadm does not set the deprecated '--cgroup-driver' flag in /var/lib/kubelet/kubeadm-flags.env, it will be set in the kubelet config.yaml. If you have this flag in /var/lib/kubelet/kubeadm-flags.env or /etc/default/kubelet (/etc/sysconfig/kubelet for RPMs) please remove it and set the value using KubeletConfiguration ([#90513](https://github.com/kubernetes/kubernetes/pull/90513),...

# テンプレート { #templates }

**FastAPI** では任意のテンプレートエンジンを使用できます。

Flask などでも使われている Jinja2 が一般的な選択肢です。

Starlette によって提供され、**FastAPI** アプリで直接使える、簡単に設定できるユーティリティがあります。

## 依存関係のインストール { #install-dependencies }

[仮想環境](../virtual-environments.md) を作成して有効化し、`jinja2` をインストールします:

<div class="termy">

```console
$ pip install jinja2

---> 100%
```

</div>

## `Jinja2Templates` の使用 { #using-jinja2templates }

		f.NonUTF8 = false

- Kubeadm: only enable the klog flags that are still supported for kubeadm, rather than hiding the unwanted flags. This means that the previously unrecommended hidden flags about klog (including `--alsologtostderr`, `--log-backtrace-at`, `--log-dir`, `--logtostderr`, `--log-file`, `--log-file-max-size`, `--one-output`, `--skip-log-headers`, `--stderrthreshold`...

* The following deprecated flags were removed from `kube-controller-manager`:

  * `replication-controller-lookup-cache-size`
  * `replicaset-lookup-cache-size`
  * `daemonset-lookup-cache-size`

  Don't use these flags. Using deprecated flags causes the server to print a warning. Using a removed flag causes the server to abort the startup.

* The following deprecated flags were removed from `kubelet`:

# 更大型的應用程式 - 多個檔案 { #bigger-applications-multiple-files }

如果你正在建置一個應用程式或 Web API，很少會把所有東西都放在單一檔案裡。

FastAPI 提供了一個方便的工具，讓你在維持彈性的同時，幫你組織應用程式的結構。

如果你來自 Flask，這相當於 Flask 的 Blueprints。

  - The deprecated `--etcd-quorum-read` flag has been removed. Quorum reads are now always enabled when fetching data from etcd. Remove the `--etcd-quorum-read` flag from kube-apiserver invocations before upgrading.
- kube-controller-manager
  - The deprecated `--insecure-experimental-approve-all-kubelet-csrs-for-group` flag has been removed.
- kubelet
