Installing RVM and multiple ruby versions with Puppet

rvm_logoWith the latest version of the Puppet RVM module it is even easier to install multiple versions of Ruby


# install rubies from binaries
Rvm_system_ruby {
  ensure     => present,
  build_opts => ['--binary'],
}

# ensure rvm doesn't timeout finding binary rubies
# the umask line is the default content when installing rvm if file does not exist
file { '/etc/rvmrc':
  content => 'umask u=rwx,g=rwx,o=rx
                     export rvm_max_time_flag=20',
  mode    => '0664',
  before  => Class['rvm'],
}

class { 'rvm': }
rvm::system_user { 'vagrant': }
rvm_system_ruby {
  'ruby-1.9.3':
    default_use => true;
  'ruby-2.0.0':;
  'jruby':;
}

Hiera can also be used to define what rubies to install, making the Puppet code even less verbose

...
class { 'rvm': }
# rvm::system_user no longer needed
# rvm_system_ruby no longer needed

The equivalent hiera yaml configuration to the previous example

rvm::system_rubies:
  '1.9':
    default_use: true
  '2.0': {}
  'jruby-1.7': {}

rvm::system_users:
  - vagrant
