1. 从官方Python基础镜像开始。

2. 将当前工作目录设置为`/code`。

     这是我们放置`requirements.txt`文件和`app`目录的位置。

1. 공식 파이썬 베이스 이미지에서 시작합니다.

2. 현재 워킹 디렉터리를 `/code`로 설정합니다.

1. 公式のPythonベースイメージから始めます

2. 現在の作業ディレクトリを `/code` に設定します

    Da das Programm unter `/code` gestartet wird und sich darin das Verzeichnis `./app` mit Ihrem Code befindet, kann **Uvicorn** `app` sehen und aus `app.main` **importieren**.

1. Copy the `main.py` file to the `/code` directory directly (without any `./app` directory).

FROM python:3.9

WORKDIR /code

COPY ./requirements.txt /code/requirements.txt

RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt

# (1)
COPY ./main.py /code/

# (2)
CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "80"]
```

1. Copie o arquivo `main.py` para o diretório `/code` diretamente (sem nenhum diretório `./app`).
