Register-PSRepository throws exception when run inside Windows Server container

[pcgeek86]

Problem Overview

We're trying to register an internal / private NuGet PowerShell module repository inside of a Windows Server Container. When we attempt to register the repository, an exception is thrown by the Register-PSRepository command. The repository can be registered properly outside of a Windows Server Container.

Steps to reproduce

1. Create a Dockerfile based on microsoft/windowsservercore
2. Run Register-PSRepository command inside Dockerfile

build.cmd

cd "%~dp0"

powershell.exe -Command Save-Module -Name PowerShellGet -Path ./

docker build --tag amazon/redacted --file Dockerfile --no-cache .

Dockerfile

FROM microsoft/windowsservercore

MAINTAINER Trevor Sullivan <tsulli@amazon.com>

RUN mkdir c:\Amazon

COPY [ "PackageManagement", "c:/Program Files/WindowsPowerShell/Modules/PackageManagement"]
COPY [ "PowerShellGet", "c:/Program Files/WindowsPowerShell/Modules/PowerShellGet"]
COPY redacted.ps1 c:\Amazon

RUN powershell.exe -ExecutionPolicy Bypass -File c:\Amazon\redacted.ps1

ENTRYPOINT powershell

Expected behavior

Container builds successfully, without errors.

Actual behavior

Exception is thrown:

@pcgeek86 I am able to successfully build a container using these instructions in my test environment. Here is the PSVersionTable on my machine:
