Install the latest stable version of PSRule for Azure.

- name: Analyze Azure template files
  uses: microsoft/ps-rule@v2.6.0
  with:
    modules: 'PSRule.Rules.Azure'

Install the latest stable or pre-release version of PSRule for Azure.

- name: Analyze Azure template files
  uses: microsoft/ps-rule@v2.6.0
  with:
    modules: 'PSRule.Rules.Azure'

Install the latest stable version of PSRule for Azure.

- task: ps-rule-assert@2
  displayName: Analyze Azure template files
  inputs:
    modules: 'PSRule.Rules.Azure'

Install the latest stable or pre-release version of PSRule for Azure.

- task: ps-rule-install@2
  displayName: Install PSRule for Azure (pre-release)
  inputs:
    module: PSRule.Rules.Azure
    prerelease: true

- task: ps-rule-assert@2
  displayName: Analyze Azure template files
  inputs:
    modules: 'PSRule.Rules.Azure'

This will automatically install compatible versions of all dependencies.

Installing locally#

PSRule for Azure can be installed locally from the PowerShell Gallery using PowerShell. You can also use this option to install on CI workers that are not natively supported.

PreRequisites#

Operating System Tool Overview Installation Link
Windows Windows PowerShell Support for version 5.1 with .NET Framework 4.7.2 or greater. link
Windows, MacOS, Linux PowerShell Version 7.2 or greater is support. link
- - Multiple PowerShell modules are required (PlatyPS, Pester, PSScriptAnalyzer, PowerShellGet, PackageManagement, InvokeBuild, PSRule). Installed when you run the build.ps1 script
- .NET .NET SDK v6 is required. link
- Bicep CLI PsRule depends on the Bicep CLI to decompile (expand) Bicep modules to ARM link

To use PSRule for Azure, PSRule a separate PowerShell module must be installed. The required version will automatically be installed along-side PSRule for Azure.

Additionally, the exporting data from a subscription functionality requires the additional PowerShell modules:

  • Az.Accounts
  • Az.Resources

Note

Azure PowerShell modules are not installed automatically when installing PSRule for Azure. This has been changed from v1.16.0 due to module dependency chains in Azure DevOps. In most cases these modules will be pre-installed on the CI worker. For private CI workers, consider pre-installing these modules in a previous step.

Installing PowerShell#

PowerShell 7.x can be installed on MacOS, Linux, and Windows but is not installed by default. For a list of platforms that PowerShell 7.2 is supported on and install instructions see Get PowerShell.

Getting the modules#

Tip

To install pre-release module versions, the latest version of PowerShellGet may be required.

# Install the latest PowerShellGet version
Install-Module -Name PowerShellGet -Repository PSGallery -Scope CurrentUser -Force

Tip

To install a pre-release version of PSRule and PSRule for Azure, install each in separate steps.

To install PSRule for Azure for the current user use:

Install-Module -Name PowerShellGet -Repository PSGallery -Scope CurrentUser -Force
Install-Module -Name PSRule -Repository PSGallery -Scope CurrentUser -AllowPrerelease
Install-Module -Name PSRule.Rules.Azure -Repository PSGallery -Scope CurrentUser -AllowPrerelease

Open PowerShell with Run as administrator on Windows or sudo pwsh on Linux.

To install PSRule for Azure for all users (requires admin/ root permissions) use:

Install-Module -Name PowerShellGet -Repository PSGallery -Scope CurrentUser -Force
Install-Module -Name PSRule -Repository PSGallery -Scope AllUsers -AllowPrerelease
Install-Module -Name PSRule.Rules.Azure -Repository PSGallery -Scope AllUsers -AllowPrerelease

Development dependencies#

The following dependencies will be automatically installed if the required versions are not present:

  • PowerShell modules:
    • PlatyPS
    • Pester
    • PSScriptAnalyzer
    • PowerShellGet
    • PackageManagement
    • InvokeBuild
  • Bicep CLI

These dependencies are only required for building and running tests for PSRule for Azure.

Building from source#

Source

PSRule for Azure is provided as open source on GitHub. To build PSRule for Azure from source code:

  1. Clone the GitHub repository.
  2. Run ./build.ps1 from a PowerShell terminal in the cloned path.

This build script will compile the module and documentation then output the result into out/modules/PSRule.Rules.Azure.

Troubleshooting#

If the ./build.ps1 script fails, you can start troubleshooting this by:

  • Checking the prerequisites are installed installed (and the specific versions)
    • Check the PowerShell version enter the following statement in the PowerShell terminal: $PSVersionTable.PSVersion
    • Check the installed .NET version by entering the dotnet --list-sdks command in your terminal.
  • Check if your .NET setup is connected to any Nuget repositories and if there's any connectivity or authentication issues.

Limited access networks#

If you are on a network that does not permit Internet access to the PowerShell Gallery, download the required PowerShell modules on an alternative device that has access. PowerShell provides the Save-Module cmdlet that can be run from a PowerShell terminal to do this.

The following command lines can be used to download the required modules using a PowerShell terminal. After downloading the modules, copy the module directories to devices with restricted Internet access.

To save PSRule for Azure for offline use:

$modules = @('PSRule', 'PSRule.Rules.Azure', 'Az.Accounts', 'Az.Resources')
Save-Module -Name $modules -Path '.\modules'

This will save PSRule for Azure and all dependencies into the modules sub-directory.

To save PSRule for Azure development module dependencies for offline use:

$modules = @('PSRule', 'Az.Accounts', 'Az.Resources', 'PlatyPS', 'Pester',
  'PSScriptAnalyzer', 'PowerShellGet', 'PackageManagement', 'InvokeBuild')
Save-Module -Name $modules -Repository PSGallery -Path '.\modules';

This will save required developments dependencies into the modules sub-directory.
