Question

我的名字是奥马尔。我有一个docker图像和容器，用于我刚刚创建并运行的项目。所以我目前正在尝试在我的本地机器上测试它，然后将其推送到在线环境。我构建它没有以前的缓存，它构建了一个在线运行的新docker。为什么它在我的浏览器中不起作用。这就是我所拥有的。

我尝试了以下localhost:32768和127.0.0.1:32768有没有人知道为什么会发生这种情况。

我已经允许我的django项目中的所有主机。

dockerfile

FROM python:3
WORKDIR users/
COPY requirements.txt ./
EXPOSE 80
RUN pip install -r requirements.txt
COPY . .
CMD ["python", "manage.py", "runserver"]

Answer 1

这是因为Django的runserver仅默认接受来自127.0.0.1的连接，当您从浏览器点击localhost:32768时，连接不会来自127.0.0.1 / { {1}}，但来自您的实际主机IP。

将您的localhost更改为：

CMD

docker container已构建并正在运行但无法正常工作
