【问题描述】：

我在为我的 django 应用程序创建 docker 容器时遇到了一些问题。

我有我的 Dockerfile

FROM python:3.8.6
ENV PYTHONUNBUFFERED 1

USER root

RUN apt-get -y update && \
apt -y install python3-pip && \
pip3 install setuptools gitpython && \
pip install django && \
pip install stripe && \
pip install django-extensions

RUN git clone https://github.com/***/***
WORKDIR /tfg/MiTfg
EXPOSE 8000/tcp


CMD python3 manage.py makemigrations
CMD python3 manage.py migrate
CMD python3 manage.py runserver localhost:8000

完美运行，现在我运行

docker run --network host -p 8000:8000 1fbe

输出打印：

我认为问题出在连接上，因为如果我在浏览器 localhost:8000 中运行，它会说没有服务器在该目录中运行...所以可能是 docker 和主机之间的网络有问题...？ ?

当 django 应用程序在没有 docker 的情况下在本地下载时，我可以完美运行它，因此该应用程序可以工作但不能在容器中...

请帮帮我！！！

谢谢你

【解决方案1】：

我认为您不需要 --network，只需尝试 docker run --publish 8000:8000

【解决方案2】：

首先你不能在一个 Dockerfile 中有多个 CMD，请阅读文档here

关于它没有绑定到本地端口的问题，尝试运行如下命令： docker run -p 8000:8000 <my_image>
