Dockerizing Django application: ModuleNotFoundError: No module named 'X"
Dockerizing Django application: ModuleNotFoundError: No module named 'X"
我一直在尝试按照本指南对项目进行 Dockerize：
Deploy and Run Django in Dokcer Container
这是基本文件结构：
WFMBCM
|-WFMBCM
| |-__init__.py
| |-__pycache__
| |-setting.py
| |-url.py
| |-wsgi.py
|
|-WFMBCM_App
|-WFMBCM_db
|-manage.py
|-Dockerfile
|-requirements.txt
|-runWFMBCM.sh
Docker 文件：
FROM python:3.7
ADD WFMBCM /usr/src/app
ADD WFMBCM_App /usr/src/app
ADD WFMBCM_db /usr/src/app
ADD manage.py /usr/src/app
WORKDIR /usr/src/app
COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt
EXPOSE 8000
CMD exec gunicorn wfmbcm.wsgi:application --bind 0.0.0.0:8000 --workers 3
requirements.txt:
Django==2.2.1
gunicorn==19.9.0
runWFMBCM.sh:
cd /home/admin/WFMBCM
echo -e "3[0;34mGo to WFMBCM directory.\n 3[0;37m"
echo -e "3[0;34mRemove old WFMBCM container\n 3[0;37m"
docker rm -v wfmbcm_container
echo -e "3[0;34m\nBuild WFMBCM Docker image.\n 3[0;37m"
sudo docker build -t wfmbcm .
echo -e "3[0;34m\nRun WFMBCM Docker image.\n 3[0;37m"
sudo docker run --name wfmbcm_container -p 8000:8000 -i -t wfmbcm
echo -e "3[0;34m\n\nWFMBCM run-script ended!.\n 3[0;37m"
当我 运行 runWFMBCM.sh 我得到以下输出：
Go to WFMBCM directory.
Remove old WFMBCM container
Error response from daemon: No such container: wfmbcm_container

为什么找不到wfmbcm模块？我一直在发疯和谷歌搜索但没有成功，并查看不同的堆栈溢出问题。
我找不到任何名为 wfmbcm 的 python 模块，所以我假设它是您项目中的一个应用程序。
如果您使用的是区分大小写的文件系统，那么您的文件布局会显示某些文件夹全部大写，这可能是（部分）问题。
这个项目 运行 在 docker 之外吗？
如果是这样，那么我认为最好的办法是启动 docker 容器，然后在容器中手动安装整个应用程序，并按照您的步骤更新 docker 文件去吧。
每次测试新更改时，请确保使用 --no-cache 选项进行构建，否则您可能不会测试您认为的内容。
将我的 DockerFile 更改为此解决了我的问题：
FROM python:3.7
ADD WFMBCM /usr/src/app/WFMBCM
ADD WFMBCM_App /usr/src/app/WFMBCM_App
ADD WFMBCM_db /usr/src/app/WFMBCM_db
ADD manage.py /usr/src/app
WORKDIR /usr/src/app
COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt
EXPOSE 8000
CMD manage.py migrate
CMD exec gunicorn WFMBCM.wsgi:application --bind 0.0.0.0:8000 --workers 10
只需将WFMBCM/WFMBCM/wsgi.py文件复制到项目的根目录（所以wsgi.py路径是WFMBCM/wsgi.py）
并将 CMD exec ... 更改为 CMD exec gunicorn wsgi:application --bind 0.0.0.0:8000 --workers 3
你会没事的。
