- DevOps - Built to support DevOps culture and tools.
- Extensible - Define tests using YAML, JSON, or PowerShell format.
- Reusable - Reuse and share rules across teams or organizations.
- Extensible:
- Provide an execution environment (tools and language) to validate infrastructure code.
- Handling of common concerns such as input/ output/ reporting should be handled by the engine.
- Language must be flexible enough to support a wide range of use cases.
- DevOps:
- Validation should support and enhance DevOps workflows by providing fast feedback in pull requests.
- Allow quality gates to be implemented between environments such development, test, and production.
- Cross-platform:
- A wide range of platforms can be used to author and deploy infrastructure code. PSRule must support rule validation and authoring on Linux, MacOS, and Windows.
- Runs in a Linux container. For continuous integration (CI) systems that do not support PowerShell, run in a container.
- Reusable:
- Validation should plug and play, reusable across teams and organizations.
- Any reusable validation will have exceptions. Rules must be able to be disabled where they are not applicable.

PSRule extends PowerShell with domain specific language (DSL) keywords, cmdlets and automatic variables.
The following language keywords are used by the PSRule module:
- Rule - A rule definition.
- Exists - Assert that a field or property must exist.
- Match - Assert that the field must match any of the regular expressions.
- AnyOf - Assert that any of the child expressions must be true.
- AllOf - Assert that all of the child expressions must be true.
- Within - Assert that the field must match any of the values.
- TypeOf - Assert that the object must be of a specific type.
- Reason - Return a reason for why the rule failed.
- Recommend - Return a recommendation to resolve the issue and pass the rule.
Back to the summary
The following commands exist in the PSRule module:
- Assert-PSRule - Evaluate objects against matching rules and assert any failures.
- Export-PSRuleBaseline - Exports a list of baselines to a file.
- Get-PSRule - Get a list of rule definitions.
- Get-PSRuleBaseline - Get a list of baselines.
- Get-PSRuleHelp - Get documentation for a rule.
- Get-PSRuleTarget - Get a list of target objects.
- Invoke-PSRule - Evaluate objects against matching rules and output the results.
- New-PSRuleOption - Create options to configure PSRule execution.
- Set-PSRuleOption - Sets options that configure PSRule execution.
- Test-PSRuleTarget - Pass or fail objects against matching rules.
