我有一个Django Web应用程序，我想尝试将其部署到Windows Nano Server Docker容器。该应用程序依赖于几个Windows二进制文件（.exe文件），因此我目前无法将其移植到* nix。它还取决于Pillow库。
我创建了一个以镜像stefanscherer/python-windows:nano开头的Dockerfile，该镜像似乎只是安装了Python 3.6.4的Nano Server。我有一个PowerShell脚本，该脚本处理设置venv，将文件放置在需要的位置，提取Windows二进制依赖项并将它们放置在正确的位置。
脚本运行pip install -r requirements，该脚本成功安装了列出的所有软件包。但是，当我的脚本然后运行命令python manage.py migrate来设置本地数据库时，我在Pillow中收到DLL导入错误：

我到处搜索有关此问题的任何详细信息，大多数帖子都指出Pillow 4.0和Python 3.6.0的问题。我的需求文件未指定版本，因此它拉了Pillow 5.3.0。多个帖子只是建议“升级到Python 3.6.1或更高版本，因为它可以解决DLL导入问题，和/或尝试使用Pillow 4.1.1或更高版本”。但是我在3.6.4上。我敢肯定，这个问题是特定于Nano Server的。
再往前看，我发现Pillow的.pyd文件取决于Visual C ++ 2015运行时中的库，而这些库不包含在Nano Server中。 Nano Server也没有安装程序，因此我不能仅将VC ++运行时安装程序添加到Dockerfile的命令中。 Microsoft网页上建议您只需将必要的.dll二进制文件复制到Nano Server映像中即可，它应该可以工作，因此我将所有api-ms-crt-...dll文件都复制到了Nano Server映像中的相同路径中。但是，DLL导入失败仍然会发生。
作为最后的选择，我尝试切换到服务器核心映像（python:3-msservercore）上的完整Python。失败是因为pip安装Pillow时，显然已决定需要对其进行编译，并且当然容器中没有C编译器环境。
如何进一步诊断和解决Nano Server内发生的导入错误？
