puppet-rbenv

Description

This Puppet module will install and manage rbenv. By default, it installs
rbenv for systemwide use, rather than for a user or project. Additionally,
you can install different versions of Ruby, rbenv plugins, and Ruby gems.

Installation

puppet module install --modulepath /path/to/puppet/modules jdowning-rbenv

Usage

To use this module, you must declare it in your manifest like so:

class { 'rbenv': }

If you wish to install rbenv somewhere other than the default
(/usr/local/rbenv), you can do so by declaring the install_dir:

class { 'rbenv': install_dir => '/opt/rbenv' }

You can also ensure rbenv is kept up-to-date:

class { 'rbenv':
  install_dir => '/opt/rbenv'
  latest      => true
}

The class will merely setup rbenv on your host. If you wish to install
rubies, plugins, or gems, you will have to add those declarations to your manifests
as well.

Installing Ruby using ruby-build

Ruby requires additional packages to operate properly. Fortunately, this module
will ensure these dependencies are met before installing Ruby. To install Ruby
you will need the ruby-build plugin. Once
installed, you can install most any Ruby. Additionally, you can set the Ruby to
be the global interpreter.

rbenv::plugin { 'rbenv/ruby-build': }
rbenv::build { '2.0.0-p247': global => true }

Sometimes Ruby needs to be patched prior to being compiled. puppet-rbenv
currently supports patching from a single file located either on the
Puppet Master or the local filesystem. Therefore, the only accepted paths are those
starting with puppet:/// or file:///.

rbenv::build { '2.0.0-p247': patch => 'puppet:///modules/rbenv/patch.patch' }
rbenv::build { '2.0.0-p247': patch => 'file:///path/to/patch.patch' }

Plugins

Plugins can be installed from GitHub using the following definiton:

rbenv::plugin { 'github_user/github_repo': }

You can ensure a plugin is kept up-to-date. This is helpful for a plugin like
ruby-build so that definitions are always available:

rbenv::plugin { 'rbenv/ruby-build': latest => true }

Gems

Gems can be installed too! You must specify the ruby_version you want to
install for.

rbenv::gem { 'thor': ruby_version => '2.0.0-p247' }

Full Example

site.pp

class { 'rbenv': }
rbenv::plugin { [ 'rbenv/rbenv-vars', 'rbenv/ruby-build' ]: }
rbenv::build { '2.0.0-p247':
  rubygems_version => '3.2.1',
  bundler_version => '1.17.3',
  global => true,
}
rbenv::gem { 'thor': ruby_version => '2.0.0-p247' }

Testing

You can run specs in this module with rspec:

bundle install
bundle exec rake spec

Or with Docker:

docker build -t puppet-rbenv .

Vagrant

You can also test this module in a Vagrant box. There are two box definitons included in the
Vagrant file for CentOS and Ubuntu testing. You will need to use librarian-puppet to setup
dependencies:

bundle install
bundle exec librarian-puppet install

To test both boxes:

vagrant up

To test one distribution:

vagrant up [centos|ubuntu]
