Dann müssten Sie nur noch die entsprechenden Pfade ändern, um die Datei im `Dockerfile` zu kopieren:

```{ .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/

# (2)

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

Then you would just have to change the corresponding paths to copy the file inside the `Dockerfile`:

```{ .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/

# (2)

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

Então você só teria que alterar os caminhos correspondentes para copiar o arquivo dentro do `Dockerfile`:

```{ .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/

# (2)

But for security, the `password` won't be in other Pydantic *models*, for example, it won't be sent from the API when reading a user.

=== "Python 3.10+"

    ```Python hl_lines="1  4-6  9-10  21-22  25-26"
    {!> ../../../docs_src/sql_databases/sql_app_py310/schemas.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="3  6-8  11-12  23-24  27-28"

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/

# (2)

```

├── main.py
└── requirements.txt
```

    if (collection instanceof Set && collection.size() > set.size()) {

そうすれば、`Dockerfile`の中にファイルをコピーするために、対応するパスを変更するだけでよいです：

```{ .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/
