[Feature]: Create mirror for when PowerShell Gallery is down

[o-l-a-v]

Description of the new feature

PowerShell Gallery is not reliable, and currently it experiences problems due to the *.azureedge.net CDN retirement.

• What happens with PowerShell Gallery when Edgio / `azureedge.net` CDN goes down? PowerShell/PowerShell#24734
• NXDOMAIN results for the psg-prod-eastus.azureedge.net domain are breaking package downloads PowerShell/PowerShellGallery#297

I have a meta issue / feature request that tracks more issues I've encountered.

• [Feature]: Add hosting of PowerShell modules and scripts NuGet/NuGetGallery#10071

AWS hosts a mirror of their modules, which is great for when PowerShell Gallery is down.

• Announcement: AWS.Tools Offline Installer aws/aws-tools-for-powershell#107 (comment)
• Links to latest:
  • https://sdk-for-net.amazonwebservices.com/ps/v4/latest/AWS.Tools.zip
  • https://sdk-for-net.amazonwebservices.com/ps/v4/latest/AWSPowerShell.NetCore.zip
  • https://sdk-for-net.amazonwebservices.com/ps/v4/latest/AWSPowerShell.zip

Maybe you could do the same?

Proposed implementation details (optional)

Add release artifacts as ZIP to GitHub releases?

• Az currently releases MSI installers, which is helpful for Windows users. Linux and Mac?

Publish modules to MCR too? Seems you've started testing with that already.

Hi @o-l-a-v thanks for bringing this up! A mirror gallery makes sense, but since we are investing in MCR already we might not want to start working on a new solution. We'll share the progress later.

As for the offline options, besides MSI installer, we also offer a tar archive for Linux and MacOS. Check out Install from tar archive

Following the Install from tar archive guide, the PowerShell command to get URL for latest TAR archive does not work / return anything.

$tarSourceUrl = (
    Invoke-RestMethod -Uri https://api.github.com/repos/azure/azure-powershell/releases/latest |
    Select-Object -ExpandProperty assets | Where-Object content_type -eq 'application/x-gzip'
).browser_download_url

Seems the latest release does not have any assets?

Edit: The latest one I could find with assets is v13.1.0:

• https://github.com/Azure/azure-powershell/releases/tag/v13.1.0-January2025

Apologies. I've marked Az v13.1.0 latest so it works now. Will keep it that way in the future.
