Ansible role that compiles and installs Ruby and Bundler. This role is generic enough to support any version of Ruby, and it is best used in conjunction with another role that supplies the required variables and that depends on this common base.
For example, the following roles use ruby-common:
Variables that must be set by the user (or another role)
ruby_version: This variable controls the version of Ruby that will be compiled and installed. It should correspond with the tarball filename excluding the ".tar.gz" extension (e.g. "ruby-1.9.3-p484").
ruby_checksum: The SHA256 checksum of the gzipped tarball that will be downloaded and compiled.
ruby_download_location: The URL that the tarball should be retrieved from. Using the ruby_version variable within this variable is a good practice (e.g. "http://cache.ruby-lang.org/pub/ruby/1.9/{{ ruby_version }}.tar.gz").
Variables that can be set by the user (or another role)
rails_env: This role includes a convenient shell script that lets you invoke Rake commands using Bundler with the proper RAILS_ENV environment variable set. This script is placed in /usr/local/bin/rake-env. This can be useful in other tasks (e.g. if you wanted to run a Rake task using the command module). This variable is used to control the Rails environment for this script and is set to "production" by default.
ruby_bundler_flags: This variable controls any extra flags that you would like to be passed to RubyGems when Bundler is first installed. For example, you can set this to "--no-document" to disable documentation generation, or "--version VERSION" to install a particular version of Bundler. The default is blank, and no extra flags are passed.
This role also includes a GC wrapper shell script that lets you tune the Ruby garbage collection settings. This script is placed in /usr/local/bin/ruby-gc-wrapper. These three variables are used within the template that generates this script:
ruby_free_min: Sets the RUBY_FREE_MIN environment variable.
ruby_gc_malloc_limit: Sets the RUBY_GC_MALLOC_LIMIT environment variable.
ruby_heap_min_slots: Sets the RUBY_HEAP_MIN_SLOTS environment variable.
These variables are blank by default (i.e. they do not change the GC settings at all) and your chosen GC settings will only be used if the ruby-gc-wrapper executable is used instead of ruby.
Variables that are set by the role itself (and that shouldn't need to be modified)
ruby_apt_dependencies: Controls the installation of dependencies that are necessary in order to properly compile Ruby on Debian and Ubuntu. Includes libreadline-dev, libssl-dev, libyaml-dev, and zlib1g-dev by default.
ruby_yum_dependencies: Controls the installation of dependencies that are necessary in order to properly compile Ruby on Amazon Linux, CentOS, and Red Hat. Includes readline-devel, openssl-devel, libyaml-devel, and zlib-devel by default.
ruby_symlinks: Controls which binaries will be symlinked into /usr/local/bin. Includes bundle, erb, gem, irb, rake, rdoc, ri, ruby, and testrb by default.
ruby_location: Controls where Ruby will be installed and is set to "/opt/{{ ruby_version }}" by default.
ruby_executable: Provides a convenient pointer to the Ruby binary that lets you run Ruby commands from other roles. It is set to "{{ ruby_location }}/bin/ruby" by default.
