API 系統需要的主要功能之一是資料「<dfn title="也稱為 marshalling、轉換">序列化</dfn>」，也就是把程式中的資料（Python）轉成能透過網路傳輸的形式。例如，將含有資料庫資料的物件轉成 JSON 物件、把 `datetime` 物件轉成字串等等。

API 需要的另一個重要功能是資料驗證，確保資料在特定條件下有效。例如，某個欄位必須是 `int`，而不是隨便的字串。這對於輸入資料特別有用。

沒有資料驗證系統的話，你就得在程式碼中手動逐一檢查。

這些功能正是 Marshmallow 所要提供的。它是很棒的函式庫，我之前也大量使用。

但它誕生於 Python 型別提示出現之前。因此，為了定義每個 <dfn title="資料應如何組成的定義">結構（schema）</dfn>，你需要使用 Marshmallow 提供的特定工具與類別。

- Kubeadm: added `show-join-command` as a new separate phase at the end of `kubeadm init`. You can skip printing the join information by using `kubeadm init --skip-phases=show-join-command`. Executing only this phase on demand will throw an error because the phase needs dependencies such as bootstrap tokens to be pre-populated. ([#111512](https://github.com/kubernetes...

`v1beta1.KubeletConfiguration`. The new patch target is called `kubeletconfiguration` (e.g. patch file `kubeletconfiguration+json.json`).This makes it possible to apply node specific KubeletConfiguration options during `init`, `join` and `upgrade`, while the main `KubeletConfiguration` that is passed to `init` as part of the `--config` file can still act as the global stored in the cluster `KubeletConfiguration`.
