Switch to using PSResourceGet for module installation + add PSGallery as repository if not present

[info] Using repository: PSGallery
[info] Installing PSRule: 2.9.0
Get-PackageSource: Unable to find repository 'PSGallery'. Use Get-PSRepository to see all
available repositories.
Error: Process completed with exit code 1

Describe the solution you'd like

PSResourceGet is the successor to PowerShellGet and PackageManagement. It's included in the GitHub workers. Use it.

• Edit: Seems you are using it already through aliases? Better to use the native cmdlets then IMO. :)

Relevant code section:

• ps-rule/powershell.ps1

  Lines 158 to 206 in 001a0fc

  	Write-Host "[info] Using repository: $Repository";
  	$installed = @(Get-InstalledModule -Name PSRule @checkParams -ErrorAction Ignore)
  	if ($installed.Length -eq 0) {
  	Write-Host "[info] Installing PSRule: $($checkParams.RequiredVersion)";
  	$Null = Install-Module -Repository $Repository -Name PSRule @checkParams -Scope CurrentUser -Force;
  	}
  	foreach ($m in $installed) {
  	Write-Host "[info] Using existing module $($m.Name): $($m.Version)";
  	}
  	# Look for existing modules
  	Write-Host '';
  	$moduleNames = @()
  	if (![String]::IsNullOrEmpty($Modules)) {
  	$moduleNames = $Modules.Split(',', [System.StringSplitOptions]::RemoveEmptyEntries);
  	}
  	$moduleParams = @{
  	Scope = 'CurrentUser'
  	Force = $True
  	}
  	if ($PreRelease -eq 'true') {
  	$moduleParams['AllowPrerelease'] = $True;
  	}
  	# Install each module if not already installed
  	foreach ($m in $moduleNames) {
  	$m = $m.Trim();
  	Write-Host "> Checking module: $m";
  	try {
  	if ($Null -eq (Get-InstalledModule -Name $m -ErrorAction Ignore)) {
  	Write-Host ' - Installing module';
  	$Null = Install-Module -Repository $Repository -Name $m @moduleParams -AllowClobber -ErrorAction Stop;
  	}
  	else {
  	Write-Host ' - Already installed';
  	}
  	# Check
  	if ($Null -eq (Get-InstalledModule -Name $m)) {
  	Write-Host " - Failed to install";
  	}
  	else {
  	Write-Host " - Using version: $((Get-InstalledModule -Name $m).Version)";
  	}
  	}
  	catch {
  	Write-Host "::error::An error occurred installing a dependency module '$m'. $($_.Exception.Message)";
  	$Host.SetShouldExit(1);
  	}
  	}

As the error shows: Add PSGallery as repository if not already present. It can be done with Register-PSRepository -Default, ref:

• https://learn.microsoft.com/en-us/powershell/module/powershellget/register-psrepository#-default

Maybe something like this?

if ((Get-PSRepository -WarningAction 'SilentlyContinue').'Name' -notcontains 'PSGallery') {
    Register-PSRepository -Default
}

Describe alternatives you've considered

Install modules in the GitHub action before running the psrule step.

Additional context

We added this to our workflow before running PSRule.

        continue-on-error: false
        shell: pwsh
        run: |

          $ErrorActionPreference = 'Stop'
          $InformationPreference = 'Continue'
          # Import PSResourceGet
          Write-Information -MessageData 'Import module "Microsoft.PowerShell.PSResourceGet".'
          $null = Import-Module -Name 'Microsoft.PowerShell.PSResourceGet'
          # Add PSGallery if not present
          Write-Information -MessageData 'Add PSGallery as repository if not already present.'
          if ((Get-PSRepository -WarningAction 'SilentlyContinue').'Name' -notcontains 'PSGallery') {
              Write-Information -MessageData '  Was not already present, adding it now.'
              Register-PSRepository -Default
          }

Thanks for reporting the issue @o-l-a-v.

• Is this a private/ self-hosted runner or a GitHub hosted runner?
• Are you able to details from the Set up job section, including runner version, operating system, and runner image?

[o-l-a-v]

Public GitHub action worker.

Set up job section from the run that failed:

Complete job name: ps-rule-job / Analyze Azure template files

This job runs on multiple repos once a week, have never seen that specific error before. So looks like a one off. That maybe could be guarded against by adding PSGallery if not already added as module repository.

@o-l-a-v Thanks for the additional information.
