Tired of searching for dependencies on the forge and hoping you got everything? Have an existing Puppetfile that's getting long in the tooth? Use generate-puppetfile to generate a list of modules and their dependencies, at the latest version, in Puppetfile format for use with r10k or librarian-puppet.

Installation

gem install generate-puppetfile

Usage

Run generate-puppetfile with a list of modules and/or an existing Puppetfile. Each module name will be validated to be of the proper format (author/name). Any existing Puppetfile will be scanned for forge modules. Non-forge module entries will be preserved. All forge modules will be tracked at the latest version, along with their dependencies. The resulting Puppetfile will contain all the forge modules along with any preserved non-forge module statements.

Forge Modules Only

$ generate-puppetfile echocat/nfs rnelson0/certs

Installing modules. This may take a few minutes.

extending puppet modules & bolt projects

Due to the nature of the generate-puppetfile gem it makes an excellent tool for developing the Puppetfile for bolt projects. Seeing the simplest way to create a Bolt project is with the Puppet PDK this approach extends that use case. Add the following to your .sync.yml in a pdk managed module and run pdk update.zd

Gemfile:
  optional:
    ':development':
      - gem: 'generate-puppetfile'
        version: '~> 1.0

Add the following to /rakelib/generate_puppetfile.rake to create a rake target for the experimental pdk bundle feature. You can then use pdk bundle exec rake generate_puppetfile to generate the puppetfile based on the modules metadata.

require 'json'

desc 'generate puppetfile'
task :generate_puppetfile, [:mod] do |t, args| 
    args.with_defaults(:mod => JSON.parse(File.read('metadata.json'))['name'])
    sh "generate-puppetfile -c  #{args.mod}"
end

Add the following to /rakelib/generate_fixturesfile.rake to create a rake target for the experimental pdk bundle feature. You can then use pdk bundle exec rake generate_fixturesfile to generate the .fixtures.yaml based on the module metadata to aid in testing with the pdk test feature.

desc 'generate fixtures'
task :generate_fixturesfile do |t| 
    mod = JSON.parse(File.read('metadata.json'))['name']
    sh "generate-puppetfile -f -p ./Puppetfile #{mod} --fixtures-only -m #{mod}"
end

Limitations

• There is no defined standard for a Puppetfile's contents. generate-puppetfile knows about some of the most common types of module references and attempts to treat them as references instead of strings. Any unknown references will be appended as raw content following the known references.
• Verify that no ordering errors are introduced before using the new file.
