Not working in Linux PowerShell with Register-PSRepository on a Ubuntu docker image

[7wingfly]

How is this supposed to work in a Linux docker container with Register-PSRepository / Register-PackageSource? I seem to be having the same issue that's described here where these commands fail due to a missing file (possibly nuget.exe)

I'm setting this up in my docker file like so:

FROM ubuntu:22.04

RUN wget https://packages.microsoft.com/config/ubuntu/22.04/packages-microsoft-prod.deb && dpkg -i packages-microsoft-prod.deb

RUN apt-get update && apt-get install -y --no-install-recommends \         
  curl jq git gnupg zip unzip iputils-ping libcurl4 libunwind8 netcat libssl1.0 openssh-client \
  lxc iptables apt-transport-https powershell software-properties-common dotnet-sdk-8.0\
  && apt autoremove -y \
  && rm -rf /var/lib/apt/lists/*  

ARG ADO_USER="user@company.com"
ARG ADO_TOKEN="somevalidtoken"
ARG ADO_SOURCE="PSNuGet"
ARG ADO_URL="https://pkgs.dev.azure.com/company/_packaging/${ADO_SOURCE}/nuget/v2"

ENV NUGET_CREDENTIALPROVIDER_SESSIONTOKENCACHE_ENABLED="True"
ENV VSS_NUGET_EXTERNAL_FEED_ENDPOINTS="{\"endpointCredentials\": [{\"endpoint\":\"${ADO_URL}\", \"username\":\"${ADO_USER}\", \"password\":\"${ADO_TOKEN}\"}]}"

RUN curl -L https://raw.githubusercontent.com/Microsoft/artifacts-credprovider/master/helpers/installcredprovider.sh  | sh
ENV PATH="${PATH}:/root/.nuget/plugins/netcore/CredentialProvider.Microsoft"

But when I run the Register-PSRepository command I get these errors

Register-PSRepository `
    -Name "PSNuGet" `
    -SourceLocation "https://pkgs.dev.azure.com/company/_packaging/PSNuGet/nuget/v2" `
    -PublishLocation "https://pkgs.dev.azure.com/company/_packaging/PSNuGet/nuget/v2" `
    -InstallationPolicy Trusted

The plugin does seem to work by itself in that its able to find the credentials with this command

dotnet ~/.nuget/plugins/netcore/CredentialProvider.Microsoft/CredentialProvider.Microsoft.dll -Uri "https://pkgs.dev.azure.com/company/_packaging/PSNuGet/nuget/v2" -Verbosity Debug

If I register the package source and then attempt to install a module I get similar errors

What am I missing here?

For PowerShellGet, you need to pass the cred object to the install command each time. For PSResourceGet (the new version), we are working with the PowerShell folks to support credential providers here. Until then, there is the SecretManagement and SecretStore modules.
