Install all DSC Resources in a Repository

August 28, 2015 dsc powershell

Something quick for Friday morning! Are you feeling enthusiastic about DSC? Do you want to update or install every DSC resource in a repository onto your computer?

Try this (only on PowerShell 5.0 computers - what do you mean you’re not using PowerShell 5.0?!):

Find-DscResource |
    Select-Object -ExpandProperty ModuleName -Unique |
    ForEach-Object { Install-Module -Name $_ -Force }

This downloads and installs (or updates, if you have older versions) every DSC resource in all PowerShell repositories registered on your computer. It can take a while.

If you want to limit the action to a specific repository, do this:

$RepoName = 'PSGallery'

Find-DscResource -Repository $RepoName |
    Select-Object -ExpandProperty ModuleName -Unique |
    ForEach-Object { Install-Module -Name $_ -Repository $RepoName -Force }

Important: only install DSC resources from repositories you trust. Mark trusted repositories so you don’t have to confirm each module installation:

Set-PSRepository -Name 'PSGallery' -InstallationPolicy Trusted
