PSRule

A cross-platform module to validate infrastructure as code (IaC) and objects using PowerShell rules. PSRule works great and integrates with popular continuous integration (CI) systems.

Open in vscode.dev

Summary

Features of PSRule include

  • 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.

Project objectives

  1. 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.
  2. 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.
  3. 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.
  4. 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.
