Ruby Official documentation

Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. It has an elegant syntax that is natural to read and easy to write.

Multiple versions of Ruby (and gems) can be installed with rbenv. The various versions are globally available in /opt/rbenv.

Examples

  • System only

    services:
  ruby: '*'

configuration:
  ruby:
    gems:
      - rails
      - compass

    We are installing here the default version of Ruby available on the system via the package manager (apt), and install globally the gems rails and compass

  • Single custom version

    services:
  ruby: '*'

configuration:
  ruby:
    versions:
      1.9.3-p551: {}
    gems:
      - compass

    We are installing here both the default version of Ruby available on the system via the package manager (apt), and the version 1.9.3-p551. We install as well compass using the system version of Ruby, but install no extra gems with the 1.9.3-p551 version.

  • Multiple custom versions

    services:
  ruby: '*'

configuration:
  ruby:
    versions:
      1.9.3-p551:
        gems:
          - rails
      2.0.0-p598:
        gems:
          - rails

    We are installing here the default version of Ruby available on the system via the package manager (apt), as well as 2 extra versions of Ruby (1.9.3-p551 and 2.0.0-p598). No gems are installed for the system version of Ruby, but rails is installed for both extra versions of Ruby.

Plugins of rbenv

The following rbenv plugins are installed to ease the overall experience:

  • ruby-build: is used to build the requested versions of Ruby

Since the Ruby versions are built from source, the sync operation may take longer than expected and depends on the computing power of the your server.
