如果你的 FastAPI 是单个文件，例如没有`./app`目录的`main.py`，则你的文件结构可能如下所示：

```
.
├── Dockerfile
├── main.py
└── requirements.txt
```

然后你只需更改相应的路径即可将文件复制到`Dockerfile`中：

```{ .dockerfile .annotate hl_lines="10  13" }
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/

그러면 여러분들은 `Dockerfile` 내에 있는 파일을 복사하기 위해 그저 상응하는 경로를 바꾸기만 하면 됩니다:

```{ .dockerfile .annotate hl_lines="10  13" }
FROM python:3.9

WORKDIR /code

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

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