Perl installation fails in docker

I am trying to install ActivePerl in a Windows docker image based on and it fails like this:

PS C:\TEMP> powershell -Command "& $([scriptblock]::Create((New-Object Net.WebClient).DownloadString(''))) -activate-default ActiveState/Perl-5.32"

Is there anything I can do to fix the issue?

@giallu Thanks for posting, the team will look into this and advise accordingly.

Hi @giallu, we use the state tool internally in Windows containers but we install it slightly differently. The one-line install script is best suited for interactive installs. In a Dockerfile, you can install the state tool like this:

# escape=`

# Windows Server 2019
SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue';"]

# Change registry to turn off Windows Advanced Threat Protection
RUN ("Set-ItemProperty -Path 'HKLM:SOFTWARE\Policies\Microsoft\Windows Advanced Threat Protection' -Name 'ForceDefenderPassiveMode' -Value '1' -Type 'DWORD'")

SHELL ["cmd", "/S", "/C"]

# Install the state tool
ADD C:\Temp\install.ps1
RUN powershell C:\Temp\install.ps1 -n -t C:\ActiveState

Hope this is useful for you.

Thanks Shaun, this is a step in the right direction for me, but it seems Iā€™m quickly getting into some rabbit hole :slight_smile:

In fact, I need a Perl working installation in this docker image as a prerequisite for building Qt, so now I need to understand how to use the state tool to achieve this.

Off to read some more docs!
