MSYS2 in a Windows container

Hi Stefan,

your examples and tips are great help for me.

I’m trying to build a Windows container with MSYS2 I was able to build an image based on windowsservercore. I have created a dockerfile, which downloads and installs 7z, and the latest MSYS2 tar, and extracts it:

FROM microsoft/windowsservercore
# Make sure we're in temp for the downloads
WORKDIR c:/windows/temp

# Switch to PowerShell
SHELL ["powershell", "-command"] 

RUN Invoke-WebRequest -UserAgent 'DockerCI' -outfile 7zsetup.exe http://www.7-zip.org/a/7z1604-x64.exe
RUN Invoke-WebRequest -UserAgent 'DockerCI' -outfile msys2-x86_64-latest.tar.xz http://repo.msys2.org/distrib/msys2-x86_64-latest.tar.xz 


RUN Start-Process .\7zsetup -ArgumentList '/S /D=c:/7zip' -Wait
RUN C:\7zip\7z e msys2-x86_64-latest.tar.xz -Wait
RUN C:\7zip\7z x msys2-x86_64-latest.tar -o"C:\\" 
RUN del *

#ENV PATH C:\msys64\usr\bin;C:\Windows;C:\Windows\System32
ENV MSYSTEM MSYS2

CMD powershell

So far so good. I can run the image with interactive shell - no problem: docker run -it --rm msys2

Bur when I try to execute a simple command like
C:\msys64\usr\bin\pacman.exe --help

there is no message on the stdout

What is needed to see the stdout for MSYS2 binaries in an interactive shell?

Just wanted to mention for reference purposes:

• the msys2 issue is https://github.com/Alexpux/MSYS2-packages/issues/1490

I have a use case for git in a Windows 10 Pro Docker Container. ssh and ssh utilities do not operate. Inspecting the container event log shows a crash occured in msys-2.0.dll (below). Any idea if there is a solution or workaround?

ProviderName : Application Error Id : 1000 Message : Faulting application name: ssh-keygen.EXE, version: 0.0.0.0, time stamp: 0x0005dac8 Faulting module name: msys-2.0.dll, version: 2008.0.0.0, time stamp: 0x00000000 Exception code: 0xc0000005 Fault offset: 0x0000000000113bc5
