### Construire l'image Docker { #build-the-docker-image }

Maintenant que tous les fichiers sont en place, construisons l'image de conteneur.

* Allez dans le répertoire du projet (là où se trouve votre `Dockerfile`, contenant votre répertoire `app`).
* Construisez votre image FastAPI :

<div class="termy">

```console
$ docker build -t myimage .

---> 100%
```

</div>

            return true;
        }

        return switch (mimeType) {
        case "image/png", "image/gif", "image/jpeg", "image/bmp" -> true;
        default -> false;
        };
    }

    /**
     * Processes and saves an image from the input stream to the output file as a thumbnail.
     *
     * <p>This method reads image data, validates dimensions, applies subsampling and scaling

### `UploadFile` { #uploadfile }

`UploadFile` a les attributs suivants :

- `filename` : une `str` contenant le nom de fichier original téléversé (par ex. `myimage.jpg`).
- `content_type` : une `str` avec le type de contenu (type MIME / type média) (par ex. `image/jpeg`).

    "image/png")  format_hint="png:" ;;
    "image/jpeg") format_hint="jpeg:" ;;
    "image/bmp"|"image/x-windows-bmp"|"image/x-ms-bmp") format_hint="bmp:" ;;
    "image/vnd.adobe.photoshop"|"image/photoshop"|"application/x-photoshop"|"application/photoshop") format_hint="psd:" ;;
  esac
  ${im_cmd} -thumbnail ${image_size} "${format_hint}${target_file}" "${output_file}"
elif [[ x"${cmd_type}" = "x" ]] ; then
  echo "No filetype."

```Dockerfile
COPY ./app /code/app
```

### Build the Docker Image { #build-the-docker-image }

Now that all the files are in place, let's build the container image.

* Go to the project directory (in where your `Dockerfile` is, containing your `app` directory).
* Build your FastAPI image:

<div class="termy">

```console
$ docker build -t myimage .

---> 100%
```

</div>

/// tip

```Dockerfile
COPY ./app /code/app
```

### Das Docker-Image erstellen { #build-the-docker-image }

Nachdem nun alle Dateien vorhanden sind, erstellen wir das Containerimage.

* Gehen Sie zum Projektverzeichnis (dort, wo sich Ihr `Dockerfile` und Ihr `app`-Verzeichnis befindet).
* Erstellen Sie Ihr FastAPI-Image:

<div class="termy">

```console
$ docker build -t myimage .

---> 100%
```

</div>

```Dockerfile
COPY ./app /code/app
```

### Собрать Docker-образ { #build-the-docker-image }

Теперь, когда все файлы на месте, соберём образ контейнера.

* Перейдите в директорию проекта (где ваш `Dockerfile` и директория `app`).
* Соберите образ FastAPI:

<div class="termy">

```console
$ docker build -t myimage .

---> 100%
```

</div>

/// tip | Подсказка

COPY ./app /code/app
```

### Construa a Imagem Docker { #build-the-docker-image }

Agora que todos os arquivos estão no lugar, vamos construir a imagem do contêiner.

* Vá para o diretório do projeto (onde está o seu `Dockerfile`, contendo o diretório `app`).
* Construa sua imagem FastAPI:

<div class="termy">

```console
$ docker build -t myimage .

---> 100%
```

</div>

/// tip | Dica

```Dockerfile
COPY ./app /code/app
```

### 构建 Docker 镜像 { #build-the-docker-image }

现在所有文件都就位了，开始构建容器镜像。

* 进入项目目录（`Dockerfile` 所在位置，包含 `app` 目录）
* 构建你的 FastAPI 镜像：

<div class="termy">

```console
$ docker build -t myimage .

---> 100%
```

</div>

/// tip | 提示

注意末尾的 `.`，它等价于 `./`，用于告诉 Docker 使用哪个目录来构建容器镜像。
