Overview

A tool to validate your Puppet files using puppet-lint.

This tool has been tested against the following:

1. GitHub Actions
2. Travis CI
3. CircleCI
4. BitBucket pipelines
5. Local command line

However due to the way that they are built they should work on most CICD platforms where you can run arbitrary scripts.

We provide a script which pulls the latest copy of all the CICD tools and places them in a local bin directory to allow them to be run any time locally for added validation.

Basic Usage

on: [push, pull_request]

jobs:
  build:
    name: Puppet Lint
    runs-on: ubuntu-latest

    steps:
      - name: Checkout the Repository
        uses: actions/checkout@v4

      - name: Setup Ruby 3.3
        uses: ruby/setup-ruby@v1
        with:
          ruby-version: "3.3"

      - name: Run Puppet Lint
        run: bash <(curl -s https://raw.githubusercontent.com/CICDToolbox/puppet-lint/master/pipeline.sh)

Configuration Options

The following environment variables can be set in order to customise the script.

Name	Default Value	Purpose
INCLUDE_FILES	Unset	A comma separated list of files to include for being scanned. You can also use regex to do pattern matching.
EXCLUDE_FILES	Unset	A comma separated list of files to exclude from being scanned. You can also use regex to do pattern matching.
NO_COLOR	False	Turn off the color in the output.
REPORT_ONLY	False	Generate the report but do not fail the build even if an error occurred.
SHOW_ERRORS	True	Show the actual errors instead of just which files had errors.
SHOW_SKIPPED	False	Show which files are being skipped.

If you set INCLUDE_FILES - it will skip ALL files that do not match, including anything in EXCLUDE_FILES.

You can use any combination of the above settings.

File Identification

Target files are identified using the following code:

[[ ${filename} =~ \.pp$ ]]

There is not magic type for puppet files so file -b is of not use for identifying the files.
