python - 在 Docker 容器中运行 Windows Server Core

Question

我的 Linux 容器运行得非常棒，但是在我的 Docker 容器中对 Windows Server 的更改让我抓狂!

我的 Docker 文件没有构建，尽管它和我的 linux Dockerfiles 一样简单:

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

有时我能够 Chocolately 导致无法通过 PIP 安装 scipy 或奇怪地在 5 分钟前开始，甚至安装 chocolately 失败:

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

以下是我的 Docker for Windows 安装的一些规范:

有什么想法吗？

Answer 1

我无法让 refreshenv 工作，所以我使用了多个 powershell session ，我已经包括在内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"
