Cannot set path in Windows 1809

[brianharwell]

Steps to reproduce

The following Dockerfile results in an image that either fails to build or does not set the path environment variable...

FROM mcr.microsoft.com/powershell:nanoserver-1809 as runtime
SHELL ["pwsh.exe", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';"]

# RUN setx Path "C:\foo" -> ERROR: The system cannot find registry path specified.

# RUN setx /M Path "C:\foo" -> ERROR: Access to the registry path is denied.

# RUN [Environment]::SetEnvironmentVariable("Path", "C:\foo", "User") -> Missing ')' in method call.

# RUN [Environment]::SetEnvironmentVariable('Path', 'C:\foo', 'User') -> $env:Path returns C:\Windows\system32;C:\Windows;C:\Program Files\PowerShell;

# RUN [Environment]::SetEnvironmentVariable('Path', 'C:\foo', 'Machine') -> Exception calling "SetEnvironmentVariable" with "3" argument(s): "Requested registry access is not allowed."

# RUN $env:Path = 'C:\foo' -> $env:Path returns C:\Windows\system32;C:\Windows;C:\Program Files\PowerShell;

Expected behavior

To be able to set the path environment variable

Yes, this is a know issue with the underlying image.
See #231

[TravisEz13]

Please also see #164 which you JUST commented on

[TravisEz13]

In nanoserver 1809, the method used here in the Dockerfile is the only method that will work:
https://github.com/PowerShell/PowerShell-Docker/pull/165/files#diff-27ac98a3293c888d660df1794159c00fR72

ENV PATH="$WindowsPATH;${ProgramFiles}\PowerShell"

[brianharwell]

Yes and I thought #164 was my issue but when you said it was fixed I realized my issue is different.

[brianharwell]

Thank you for the workaround

[TravisEz13]

Another workaround is to use nanoserver-1803.

[TravisEz13]

#164 was caused by the issue you were hitting. I cannot fix it because it's a nanoserver docker issue. I've been assured that it will be fixed in what should be 1909

[TravisEz13]

@brianharwell I updated the issue description in #164 to include a note about this. Could you review?

[brianharwell]

Ok thx! Great seeing you at DockerCon!

@brianharwell I updated the issue description in #164 to include a note about this. Could you review?

Looks good!

@TravisEz13 is there a way to set the path without powershell, because powershell was removed from the nanoserver base image?
I tried in 1903 and it didnt work... also 1909

ok i figured out a hack ENV PATH="C:\Windows\system32;C:\Windows;C:\Program Files\PostgreSQL\bin;C:\Program Files\node;"
something like this seems to work

[TravisEz13]

@ta32 This is off topic. You need to create a windows support ticked for that question.
