Using Regal in your build pipeline

Its possible to use Regal to lint your Rego policies in your CI/CD pipeline(s)!

This document will guide you on how to do so.

GitHub Actions

If you'd like to run Regal in GitHub actions, please consider using setup-regal. A simple .github/workflows/lint.yml to run regal on PRs could look like this, where policy contains Rego files:

name: Regal Lint
on:
  pull_request:
jobs:
  lint-rego:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v4
    - uses: StyraInc/setup-regal@v1
      with:
        # For production workflows, use a specific version, like v0.22.0
        version: latest

    - name: Lint
      run: regal lint --format=github ./policy

Please see setup-regal for more information.

GitLab CI/CD

To use Regal in GitLab CI/CD, you could for example use the following stage in your .gitlab-ci.yml:

regal_lint_policies:
  stage: regal-lint
  image:
    # For production workflows, use a specific version, like v0.22.0
    name: ghcr.io/styrainc/regal:latest
    entrypoint: ['/bin/sh', '-c']
  script:
    - regal lint ./policy --format junit > regal-results.xml
  artifacts:
    reports:
      junit: regal-results.xml
    when: always
  rules:
    - if: '$CI_PIPELINE_SOURCE == "merge_request_event"'

The above will run Regal on the policy directory when a merge request is created or updated and will show linting violations as part of the merge request.
