We run a couple of automated
scans to help you access a

given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

covermymeds/ruby — version 1.0.1 Jul 24th 2015


This module installs one or more Ruby versions via Red Hat Software Collections, as well as an optional list of gems.

The full functionality of this module requires Hiera.


To simply ensure that one or more Ruby versions are installed, use the base ruby class with an array of Ruby Software Collections names:

  class { ruby: 
    $rubies => [ 'ruby200', 'rh-ruby22', ],

The first Ruby in the array will be considered the default Ruby, and will be activated for all bash users.


Gems can be installed system-wide on a per-Ruby basis.

  ruby::gems { 'ruby193':
    gems => { 'bundler' = { 'version' => '1.0.0' },
              'rails' = { 'version' => '4.0.0' },

  ruby::gems { 'rh-ruby22':
    gems => { 'bundler' = { 'version' => '1.10.6' },
              'rails'   = { 'version' => '4.2.3' },

Any Gem executable (binary or script) will be installed into /opt/rh/<ruby>/root/usr/local/bin, and that directory will be added to the PATH environment variable inside the relevant Software Collection enable script. This ensures that Gem executables will be available when the Software Collection is enabled.

The default Gem installation options include --no-ridoc and --no-rdoc. If you wish to install documentation, you may do so:

  ruby::gems { 'rh-ruby22':
    gems => { 'bundler' = { 'version' => '1.10.16',
                            'ridoc'   => true,
                            'rdoc'    => true,

Please note that the ruby::gems defined type is a wrapper around the ruby::gem defined type. You may use the latter, if you wish, but please consult the code for details. You're likely better off using ruby::gems unless you have very specific needs.


This module is completely compatible with Hiera, and indeed works best with it.

To install multiple Software Collections Rubies from Hiera:

    - ruby200
    - rh-ruby22

The first Ruby in the array will be considered the default Ruby, and will be activated for all bash users.

The base Ruby class performs an explicit hiera_hash() lookup for gems to install across all Ruby versions.

One or more gems may be installed for each Ruby version using the ruby::gems Hiera hash. The version of each gem to install is mandatory.

    version: 1.7.3

If you have gems that are only to be installed to a specific SCL Ruby version, you can add another Hiera hash named after the Ruby version:

    version: 1.1.0

The above will ensure that the rubygems-bundler gem will only be installed to Ruby 1.9.3, regardless of what other Rubies are installed.

The default for SCL gems is to pass --no-ridoc and --no-rdoc to the installation command. If you would like to install documentation, add the appropriate boolean to the gem hash entry:

    version: 1.7.3
    ridoc: true
    rdoc: true
