Question

我正在尝试使用Dockerfile的自定义映像在GAE上部署Django应用。我遵循Google提供的example。但是我在最后一步有问题：

CMD gunicorn -b :$PORT main:app

我已经尝试了好几种方法，但是一直在说找不到我的模块。

我尝试过的：

CMD gunicorn -b :$PORT wsgi:app

CMD gunicorn -b :$PORT mydjangoproject/wsgi:app

CMD gunicorn -b :$PORT mydjangoproject.wsgi

Dockerfile：

FROM solalsab/clarins:1.0.1

# Create a virtualenv for dependencies. This isolates these packages from
# system-level packages.
# Use -p python3 or -p python3.7 to select python version. Default is version 2.
RUN virtualenv /env

# Setting these environment variables are the same as running
# source /env/bin/activate.
ENV VIRTUAL_ENV /env
ENV PATH /env/bin:$PATH

# Copy the application's requirements.txt and run pip to install all
# dependencies into the virtualenv.
ADD requirements.txt requirements.txt
RUN pip install -r requirements.txt

# Add the application source code.
ADD . /app

# Run a WSGI server to serve the application. gunicorn must be declared as
# a dependency in requirements.txt.
CMD gunicorn -b :$PORT main:app

项目的结构：

+myproject/
 +mydjangoproject/
 | +wsgi.py
 | +...
 +app_template.yaml
 +generate_app_yaml.pu
 +manage.py
 +requirements.txt
 +Dockerfile

错误消息：

预先感谢您的帮助！

Answer 1

main:app部分可能来自其他代码示例（例如here），其中添加了main.py文件来引用您的应用。您可以在根目录中创建该main.py文件，然后添加：

from mydjangoproject.wsgi import application

app = application

或者像这样更新您的Dockerfile：

CMD gunicorn -b :$PORT mydjangoproject.wsgi

Answer 2

我终于通过运行成功使其运行：

CMD CD应用； exec gunicorn mydjangoproject.wsgi

在GAE上部署Django应用时，Dockerfile中存在问题
