!!! Abstract This topic covers how you can configuration continuous integration (CI) pipelines to tests Bicep and ARM templates automatically.
You can use PSRule for Azure to validate Azure resources throughout their lifecycle. By using validation within a continuous integration (CI) pipeline, any issues provide fast feedback.
Within the root directory of your infrastructure as code repository:
=== "GitHub Actions"
Create a new GitHub Actions workflow by creating `.github/workflows/analyze-arm.yaml`.
```yaml
name: Analyze templates
on:
push:
branches:
- main
pull_request:
branches:
- main
jobs:
analyze_arm:
name: Analyze templates
runs-on: ubuntu-latest
steps:
- name: Checkout
uses: actions/checkout@v3
# Analyze Azure resources using PSRule for Azure
- name: Analyze Azure template files
uses: microsoft/[email protected]
with:
modules: 'PSRule.Rules.Azure'
```
=== "Azure Pipelines"
Create a new Azure DevOps YAML pipeline by creating `.azure-pipelines/analyze-arm.yaml`.
```yaml
steps:
# Analyze Azure resources using PSRule for Azure
- task: ps-rule-assert@2
displayName: Analyze Azure template files
inputs:
modules: 'PSRule.Rules.Azure'
```
=== "Generic with PowerShell"
Create a pipeline in any CI environment by using PowerShell.
```powershell
# Analyze Azure resources using PSRule for Azure
$modules = @('PSRule.Rules.Azure')
Install-Module -Name $modules -Scope CurrentUser -Force -ErrorAction Stop;
Assert-PSRule -InputPath '.' -Module $modules -Format File -ErrorAction Stop;
```
This will automatically install compatible versions of all dependencies.
!!! Tip If this is your first time implementing PSRule for Azure on a live repository, you may want to consider setting continue on error. This will allow you to try out PSRule without preventing pull requests (PRs) from being merged.
Several parameters are available to customize the behavior of the pipeline.
In addition, many of these parameters are also available as configuration options configurable within ps-rule.yaml.
Some of the most common parameters are listed below. For a full list of parameters see the readme for GitHub Actions or Azure Pipelines.
By default, PSRule will scan all files and folders within the repository or current working path.
You can use the inputPath parameter to limit the analysis to a specific file or directory path.
!!! Tip
The inputPath parameter only accepts a relative path.
Both file and directory paths are supported.
For example: azure/modules/ if you have a azure/modules/ directory in the root of your repository.
Be careful not to specify a leading / such as /azure/modules/.
On Linux / is the root directory, which makes this a fully qualified path instead of a relative path.
=== "GitHub Actions"
```yaml hl_lines="6"
# Analyze Azure resources using PSRule for Azure
- name: Analyze Azure template files
uses: microsoft/[email protected]
with:
modules: 'PSRule.Rules.Azure'
inputPath: azure/modules/
```
=== "Azure Pipelines"
```yaml hl_lines="6"
# Analyze Azure resources using PSRule for Azure
- task: ps-rule-assert@2
displayName: Analyze Azure template files
inputs:
modules: 'PSRule.Rules.Azure'
inputPath: azure/modules/
```
=== "Generic with PowerShell"
```powershell hl_lines="4"
# Analyze Azure resources using PSRule for Azure
$modules = @('PSRule.Rules.Azure')
Install-Module -Name $modules -Scope CurrentUser -Force -ErrorAction Stop;
Assert-PSRule -InputPath 'azure/modules/' -Module $modules -Format File -ErrorAction Stop;
```
You can set the baseline parameter to specify the name of a baseline to use.
A baseline is a set of rules and configuration.
PSRule for Azure ships with multiple baselines to choose from.
See working with baselines for more information.
=== "GitHub Actions"
```yaml hl_lines="6"
# Analyze Azure resources using PSRule for Azure
- name: Analyze Azure template files
uses: microsoft/[email protected]
with:
modules: 'PSRule.Rules.Azure'
baseline: Azure.GA_2023_09
```
=== "Azure Pipelines"
```yaml hl_lines="6"
# Analyze Azure resources using PSRule for Azure
- task: ps-rule-assert@2
displayName: Analyze Azure template files
inputs:
modules: 'PSRule.Rules.Azure'
baseline: Azure.GA_2023_09
```
=== "Generic with PowerShell"
```powershell hl_lines="4"
# Analyze Azure resources using PSRule for Azure
$modules = @('PSRule.Rules.Azure')
Install-Module -Name $modules -Scope CurrentUser -Force -ErrorAction Stop;
Assert-PSRule -InputPath '.' -Baseline 'Azure.GA_2023_09' -Module $modules -Format File -ErrorAction Stop;
```
By default, PSRule breaks or stops the pipeline if any rules fail or errors occur. When adopting PSRule for Azure or a new baseline you may want to run PSRule without stopping the pipeline.
To do this, configure the PSRule for Azure step to continue on error.
=== "GitHub Actions"
Set the `continue-on-error` property to `true`.
```yaml hl_lines="4"
# Analyze Azure resources using PSRule for Azure
- name: Analyze Azure template files
uses: microsoft/[email protected]
continue-on-error: true
with:
modules: 'PSRule.Rules.Azure'
```
=== "Azure Pipelines"
Set the `continueOnError` property to `true`.
```yaml hl_lines="4"
# Analyze Azure resources using PSRule for Azure
- task: ps-rule-assert@2
displayName: Analyze Azure template files
continueOnError: true
inputs:
modules: 'PSRule.Rules.Azure'
```
=== "Generic with PowerShell"
Set the `ErrorAction` parameter of `Assert-PSRule` to `Continue`.
```powershell hl_lines="4"
# Analyze Azure resources using PSRule for Azure
$modules = @('PSRule.Rules.Azure')
Install-Module -Name $modules -Scope CurrentUser -Force -ErrorAction Stop;
Assert-PSRule -InputPath '.' -Module $modules -Format File -ErrorAction Continue;
```
You can add additional modules to the modules parameter by using comma (,) separating each module name.
=== "GitHub Actions"
```yaml hl_lines="5"
# Analyze Azure resources using PSRule for Azure
- name: Analyze Azure template files
uses: microsoft/[email protected]
with:
modules: 'PSRule.Rules.Azure,PSRule.Monitor'
```
=== "Azure Pipelines"
```yaml hl_lines="5"
# Analyze Azure resources using PSRule for Azure
- task: ps-rule-assert@2
displayName: Analyze Azure template files
inputs:
modules: 'PSRule.Rules.Azure,PSRule.Monitor'
```
=== "Generic with PowerShell"
```powershell hl_lines="2"
# Analyze Azure resources using PSRule for Azure
$modules = @('PSRule.Rules.Azure', 'PSRule.Monitor')
Install-Module -Name $modules -Scope CurrentUser -Force -ErrorAction Stop;
Assert-PSRule -InputPath '.' -Module $modules -Format File -ErrorAction Stop;
```
You can configure PSRule to output results into a file by using the outputFormat and outputPath parameters.
For details on the formats that are supported see analysis output.
=== "GitHub Actions"
```yaml hl_lines="6-7"
# Analyze Azure resources using PSRule for Azure
- name: Analyze Azure template files
uses: microsoft/[email protected]
with:
modules: 'PSRule.Rules.Azure'
outputFormat: Sarif
outputPath: reports/ps-rule-results.sarif
```
=== "Azure Pipelines"
```yaml hl_lines="6-7"
# Analyze Azure resources using PSRule for Azure
- task: ps-rule-assert@2
displayName: Analyze Azure template files
inputs:
modules: 'PSRule.Rules.Azure'
outputFormat: Sarif
outputPath: reports/ps-rule-results.sarif
```
=== "Generic with PowerShell"
```powershell hl_lines="4"
# Analyze Azure resources using PSRule for Azure
$modules = @('PSRule.Rules.Azure')
Install-Module -Name $modules -Scope CurrentUser -Force -ErrorAction Stop;
Assert-PSRule -InputPath '.' -OutputFormat 'Sarif' -OutputPath 'reports/ps-rule-results.sarif' -Module $modules -Format File -ErrorAction Stop;
```
Configuration options for PSRule for Azure are set within the ps-rule.yaml file.
To set options, create a new file named ps-rule.yaml in the root directory of your repository.
!!! Tip This file should be committed to your repository so it is available when your pipeline runs.
PSRule for Azure can automatically expand Azure template parameter files. When enabled, PSRule for Azure automatically resolves parameter and template file context at runtime.
To enabled this feature, set the Configuration.AZURE_PARAMETER_FILE_EXPANSION option to true.
This option can be set within the ps-rule.yaml file.
configuration:
# Enable automatic expansion of Azure parameter files
AZURE_PARAMETER_FILE_EXPANSION: truePSRule for Azure can automatically expand Bicep source files.
When enabled, PSRule for Azure automatically expands and analyzes Azure resource from .bicep files.
To enabled this feature, set the Configuration.AZURE_BICEP_FILE_EXPANSION option to true.
This option can be set within the ps-rule.yaml file.
configuration:
# Enable automatic expansion of bicep source files
AZURE_BICEP_FILE_EXPANSION: truePSRule for Azure comes with many configuration options. The setup section explains in detail how to configure each option.
