在Docker容器中运行Windows Server Core

Question

my Linux containers run like a charm, but the change to Windows Server in my Docker container makes me crazy!

My Docker file doesn't build although it is as simple as my linux Dockerfiles:

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

Some times I was able to Chocolately which results in a fail to install scipy via PIP or curiously starting 5 minutes ago, even the installation of chocolately fails:

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

Here are some specs on my Docker for Windows Installation:

Any ideas?

Answer 1

I was unable to get refreshenv to work, so I used multiple powershell sessions, I've included in case it is useful to someone in the future.

#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"
