How to install a powershell module within a docker container from an on-prem Azure Artifacts repository?

(https://stackoverflow.com/questions/59620118/how-to-install-a-powershell-module-within-a-docker-container-from-an-on-prem-azu)

I have the following situation:

  1. On-prem Azure DevOps Server 2019.
  2. Internal Powershell module published to the Azure Artifacts in (1).
  3. A docker container needs to install the module from (2).

I can curl the Azure Artifacts NuGet repository from within the container:

PS C:\azp> $Uri
https://tfs.xyz.com/tfs/DefaultCollection/_packaging/xyz@Release/nuget/v2
PS C:\azp> $headers

Name                           Value
----                           -----
Authorization                  Basic ***


PS C:\azp> (curl $Uri -Headers $headers -UseBasicParsing).StatusCode
200

But I cannot install the module from it:

PS C:\azp> $Name
xyz
PS C:\azp> $credential

UserName                     Password
--------                     --------
a        System.Security.SecureString


PS C:\azp> Register-PSRepository -Name $Name -SourceLocation $Uri -PublishLocation $Uri -InstallationPolicy Trusted -Credential $credential
PS C:\azp> $Params

Name                           Value
----                           -----
Name                           xyz.PS.Core
Force                          True
ErrorAction                    Stop


PS C:\azp> $RepoParam

Name                           Value
----                           -----

PS C:\azp> Install-Module @Params @RepoParam -Scope CurrentUser -Credential $credential

PS C:\azp>

The $credential object contains the PAT as the password, but since I could not specify the empty user name, I give ‘a’ instead. But it does not seem to matter.

So, I do not understand how to install a Powershell module from the Azure Artifacts when running inside a container. Is it possible at all?

P.S.

I am using Windows 10. The base image for the interactive container is created from this docker file:

FROM mcr.microsoft.com/windows/servercore:ltsc2019
COPY certificates certificates
WORKDIR /azp
COPY test.ps1 .
COPY Token.txt .token
CMD powershell .\test.ps1

Where test.ps1 is:

Get-ChildItem /certificates | ForEach-Object {
    $null = Import-Certificate -FilePath $_.FullName -CertStoreLocation Cert:\LocalMachine\Root
}
