docker - Windows兼容性:权限？

Question

操作系统Windows 10，
我正在使用Docker Engine版本18.09.2，API版本是1.39

解释运行CAT的步骤的网站是:https://libraries.io/pypi/medcat

我正在本地构建medcat镜像。在构建过程结束之前，输出看起来不错:

    Step 10/11 : ENTRYPOINT ["python"]
     ---> Using cache
     ---> 66b414e2093d
    Step 11/11 : CMD ["api.py"]
     ---> Using cache
     ---> db2acf6c4649
    Successfully built db2acf6c4649
    Successfully tagged cat:latest

当我尝试启动刚刚构建的容器时，我得到:

    OSError: [Errno 8] Exec format error: '/cat/api/api.py'

是否有人在Windows上构建过经验？安全警告与此有关吗？

更新:
我在本文中收到的答案中添加了linux可执行文件的权限。然后，我使用以下命令 docker build --network=host -t cat -f Dockerfile.MedMen .在本地构建了镜像，构建过程的最后给出了相同的 Security Warning。
然后我检查了 docker run --env-file=./envs/env_medann ubuntu:18.04 env，它给了我:

Answer 1

这是因为Windows和linux存在CR-LF和LF差异的问题，同时，需要为linux可执行文件添加权限。

对于您的情况，当您获得源代码时，我认为您已在Windows上安装了git。然后，您可以打开Git Bash，更改源代码目录的路径，然后在其中执行下一步:

找 。型f | xargs dos2unix
chmod -R 777 *

最后，重建它。

更新:

我完全尝试了您的代码，看来问题出在cat/api/api.py，但未找到#!。因此，在您的源代码中，编辑cat/api/api.py，然后在源代码的开头添加下一个:

#!/usr/bin/env python

然后，使用Dockerfile重建并再次运行它，您可以从浏览器中看到效果:
