chef-ruby_build Build Status

Description

Manages the ruby-build framework and its installed Rubies. A lightweight resources and providers (LWRP) is also defined.

Usage

Simply include recipe[ruby_build] in your run_list to have ruby-build installed. You will also have access to the ruby_build_ruby resource. See the Resources and Providers section for more details.

Requirements

Chef

Tested on 0.10.8 but newer and older version should work just fine. File an issue if this isn't the case.

Platform

The following platforms have been tested with this cookbook, meaning that the recipes and LWRPs run on these platforms without error:

  • ubuntu (10.04/10.10/11.04/11.10)

Please report any additional platforms so they can be added.

Cookbooks

There are no external cookbook dependencies. However, if you are installing JRuby then a Java runtime will need to be installed. The Opscode java cookbook can be used on supported platforms.

Installation

Depending on the situation and use case there are several ways to install this cookbook. All the methods listed below assume a tagged version release is the target, but omit the tags to get the head of development. A valid Chef repository structure like the Opscode repo is also assumed.

From the Opscode Community Platform

To install this cookbook from the Opscode platform, use the knife command:

knife cookbook site install ruby_build

Using Librarian-Chef

Librarian-Chef is a bundler for your Chef cookbooks. Include a reference to the cookbook in a Cheffile and run librarian-chef install. To install Librarian-Chef:

gem install librarian
cd chef-repo
librarian-chef init

To use the Opscode platform version:

echo "cookbook 'ruby_build'" >> Cheffile
librarian-chef install

Or to reference the Git version:

cat >> Cheffile <<END_OF_CHEFFILE
cookbook 'ruby_build',
  :git => 'git://github.com/fnichol/chef-ruby_build.git', :ref => 'v0.6.2'
END_OF_CHEFFILE
librarian-chef install

Using knife-github-cookbooks

The knife-github-cookbooks gem is a plugin for knife that supports installing cookbooks directly from a GitHub repository. To install with the plugin:

gem install knife-github-cookbooks
cd chef-repo
knife cookbook github install fnichol/chef-ruby_build/v0.6.2

As a Tarball

If the cookbook needs to downloaded temporarily just to be uploaded to a Chef Server or Opscode Hosted Chef, then a tarball installation might fit the bill:

cd chef-repo/cookbooks
curl -Ls https://github.com/fnichol/chef-ruby_build/tarball/v0.6.2 | tar xfz - && \
  mv fnichol-chef-ruby_build-* ruby_build

As a Git Submodule

A dated practice (which is discouraged) is to add cookbooks as Git submodules. This is accomplishes like so:

cd chef-repo
git submodule add git://github.com/fnichol/chef-ruby_build.git cookbooks/ruby_build
git submodule init && git submodule update

Note: the head of development will be linked here, not a tagged release.

Recipes

default

Installs the ruby-build codebase and initializes Chef to use the Lightweight Resources and Providers (LWRPs).

Attributes

git_url

The Git URL which is used to install ruby-build.

The default is "git://github.com/sstephenson/ruby-build.git".

git_ref

A specific Git branch/tag/reference to use when installing ruby-build. For example, to pin ruby-build to a specific release:

node['ruby_build']['git_ref'] = "v20111030"

The default is "master".

default_ruby_base_path

The default base path for a system-wide installed Ruby. For example, the following resource:

ruby_build_ruby "1.9.3-p0"

will be installed into "#{node['ruby_build']['default_ruby_base_path']}/1.9.3-p0" unless a prefix_path attribute is explicitly set.

The default is "/usr/local/ruby".

upgrade

Determines how to handle installing updates to the ruby-build framework. There are currently 2 valid values:

  • "none", false, or nil: will not update ruby-build and leave it in its current state.
  • "sync" or true: updates ruby-build to the version specified by the git_ref attribute or the head of the master branch by default.

The default is "none".

Resources and Providers

ruby_build_ruby

Actions

Action Description Default
install Build and install a Ruby from a definition file. See the ruby-build readme(1) for more details. Yes
reinstall Force a recompiliation of the Ruby from source. The :install action will skip a build if the target install directory already exists.  
  1. ruby-build readme

Attributes

Attribute Description Default Value
definition Name attribute: the name of a built-in definition(1) or the path to a ruby-build definition file. nil
prefix_path The path to which the Ruby will be installed. nil
user A user which will own the installed Ruby. The default value of nil denotes a system-wide Ruby (root-owned) is being targeted. Note: if specified, the user must already exist. nil
group A group which will own the installed Ruby. The default value of nil denotes a system-wide Ruby (root-owned) is being targeted. Note: if specified, the group must already exist. nil
  1. built-in definition

Examples

Install Ruby
ruby_build_ruby "1.9.3-p0" do
  prefix_path "/usr/local/ruby/ruby-1.9.3-p0"

  action      :install
end

ruby_build_ruby "jruby-1.6.5"

Note: the install action is default, so the second example is more common.

Install A Ruby For A User
ruby_build_ruby "maglev-1.0.0" do
  prefix_path "/home/deploy/.rubies/maglev-1.0.0"
  user        "deploy"
  group       "deploy"
end
Reinstall Ruby
ruby_build_ruby "rbx-1.2.4" do
  prefix_path "/opt/rbx-1.2.4"

  action      :reinstall
end

Note: the Ruby will be built whether or not the Ruby exists in the prefix_path directory.

Development

Pull requests are very welcome! Make sure your patches are well tested. Ideally create a topic branch for every separate change you make.
