## Образы контейнеров

Docker является одним оз основных инструментов для создания **образов** и  **контейнеров** и управления ими.

Существует общедоступный <a href="https://hub.docker.com/" class="external-link" target="_blank">Docker Hub</a> с подготовленными **официальными образами** многих инструментов, окружений, баз данных и приложений.

### Full Stack FastAPI PostgreSQL – Funktionen

* Vollständige **Docker**-Integration (Docker-basiert).
* Docker-Schwarmmodus-Deployment.
* **Docker Compose**-Integration und Optimierung für die lokale Entwicklung.
* **Produktionsbereit** Python-Webserver, verwendet Uvicorn und Gunicorn.

!!! tip "Заметка"
    Если вы не знаете, что такое **контейнеры**, Docker или Kubernetes, не переживайте.

    Я поведаю Вам о контейнерах, образах, Docker, Kubernetes и т.п. в главе: [FastAPI внутри контейнеров - Docker](docker.md){.internal-link target=_blank}.

## Шаги, предшествующие запуску

!!! tip
    これらの**コンテナ**やDockerそしてKubernetesに関する項目が、まだあまり意味をなしていなくても心配しないでください。
    <!-- NOTE: the current version of docker.md is outdated compared to English one. -->

    コンテナ・イメージ、Docker、Kubernetesなどについては、次の章で詳しく説明します: [コンテナ内のFastAPI - Docker](docker.md){.internal-link target=_blank}.

## 開始前の事前のステップ

アプリケーションを**開始する前**に、いくつかのステップを実行したい場合が多くあります。

        uses: mxschmitt/action-tmate@v3
        if: ${{ github.event_name == 'workflow_dispatch' && github.event.inputs.debug_enabled == 'true' }}
        with:
          limit-access-to-actor: true
      - uses: docker://tiangolo/latest-changes:0.3.0
      # - uses: tiangolo/latest-changes@main
        with:
          token: ${{ secrets.GITHUB_TOKEN }}
          latest_changes_file: docs/en/docs/release-notes.md

)


def check_file_field(field: ModelField) -> None:
    field_info = field.field_info
    if isinstance(field_info, params.Form):
        try:
            # __version__ is available in both multiparts, and can be mocked
            from multipart import __version__  # type: ignore

            assert __version__
            try:
                # parse_options_header is only available in the right multipart

지금부터 <a href="https://gunicorn.org/" class="external-link" target="_blank">**구니콘**</a>을 **유비콘 워커 프로세스**와 함께 사용하는 방법을 알려드리겠습니다.

!!! info "정보"
    만약 도커와 쿠버네티스 같은 컨테이너를 사용하고 있다면 다음 챕터 [FastAPI와 컨테이너 - 도커](docker.md){.internal-link target=_blank}에서 더 많은 정보를 얻을 수 있습니다.

    특히, 쿠버네티스에서 실행할 때는 구니콘을 사용하지 않고 대신 컨테이너당 하나의 유비콘 프로세스를 실행하는 것이 좋습니다. 이 장의 뒷부분에서 설명하겠습니다.

## 구니콘과 유비콘 워커

## Client and SDK Generators - Sponsor

There are also some **company-backed** Client and SDK generators based on OpenAPI (FastAPI), in some cases they can offer you **additional features** on top of high-quality generated SDKs/clients.

    <div class="termy">

    ```console
    $ source ./env/Scripts/activate
    ```

    </div>

To check it worked, use:

=== "Linux, macOS, Windows Bash"

    <div class="termy">

    ```console
    $ which pip

    some/directory/fastapi/env/bin/pip
    ```

    </div>
