Daphne Dockerfile #

WORKDIR /Django/gptweb

ENV PYTHONDONTWRITEBYTECODE=1 \
 PYTHONBUFFERED=1


RUN pip install --upgrade pip
COPY ./requirements.txt .
RUN pip install -r requirements.txt

COPY . .

解决步骤 #

修改项目中的asgi.py文件，将默认的设置模块路径替换为实际项目名称对应的路径：

原代码：

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'yourproject.settings')

修改为：

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'gptweb.settings')

修改后重新启动Daphne容器，问题即可解决。目前已实现Daphne与Gunicorn镜像分开运行的部署方式。
