在Docker容器中运行Windows Server Core

Question

我的Linux容器运行时很吸引人，但是Docker容器中对Windows Server的更改使我发疯了！

尽管它与Linux Dockerfile一样简单，但我的Docker文件没有构建：

FROM microsoft/windowsservercore

#Install Chocolately
RUN @powershell -NoProfile -ExecutionPolicy unrestricted -Command "(iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex)" 
ENV PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin 

#Install python
RUN choco install -fy python2
RUN refreshenv
ENV PYTHONIOINPUT=UTF-8

RUN pip install -y scipy

有时候，我能够进行Chocolately操作，这导致无法通过PIP安装scipy，或者奇怪地在5分钟前开始，即使Chocolately安装也失败了：

iwr : The remote name could not be resolved: 'chocolatey.org'
At line:1 char:2
+ (iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex)
+  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:Htt
   pWebRequest) [Invoke-WebRequest], WebException
    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShe
   ll.Commands.InvokeWebRequestCommand

这是我的Windows版Docker安装的一些规格：

有任何想法吗？

Answer 1

我无法使refreshenv正常工作，因此我使用了多个powershell会话，其中包括以防将来对某人有用。

#Install Chocolately, Python and Python Package Manager, each PowerShell session will reload the PATH from previous step
RUN @powershell -NoProfile -ExecutionPolicy unrestricted -Command "iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex" 
RUN @powershell -NoProfile -ExecutionPolicy unrestricted -Command "choco install -y python3"
