## Description of `xl.meta`

`xl.meta` is a new self describing backend format used by MinIO to support AWS S3 compatible versioning.
This file is the source of truth for each `version` at rest. `xl.meta` is a msgpack file serialized from a

/// tip | Tipp

Machen Sie sich keine Sorgen, wenn einige dieser Punkte zu **Containern**, Docker oder Kubernetes noch nicht viel Sinn ergeben.

Ich werde Ihnen in einem zukünftigen Kapitel mehr über Container-Images, Docker, Kubernetes, usw. erzählen: [FastAPI in Containern – Docker](docker.md).

Don't worry if some of these items about **containers**, Docker, or Kubernetes don't make a lot of sense yet.

## コンテナとDocker { #containers-and-docker }

次章の[コンテナ内のFastAPI - Docker](docker.md)では、その他の**デプロイメントのコンセプト**を扱うために使える戦略をいくつか説明します。

単一のUvicornプロセスを実行するために、**ゼロから独自のイメージを構築する**方法も紹介します。これは簡単なプロセスで、**Kubernetes**のような分散コンテナ管理システムを使う場合に、おそらくやりたいことでしょう。
