# <a name="title"></a> chef-rvm [![Build Status](https://secure.travis-ci.org/martinisoft/chef-rvm.png?branch=master)](http://travis-ci.org/martinisoft/chef-rvm)

## <a name="description"></a> Description

Manages system-wide and per-user [RVM][rvm]s and manages installed Rubies.
Several lightweight resources and providers ([LWRP][lwrp]) are also defined.

## <a name="usage"></a> Usage

### <a name="usage-system-rubies"></a> RVM Installed System-Wide with Rubies

Most likely, this is the typical case. Include `recipe[rvm::system]` in your
run_list and override the defaults you want changed. See below for more
details.

### <a name="usage-user-rubies"></a> RVM Installed For A Specific User with Rubies

If you want a per-user install (like on a Mac/Linux workstation for
development), include `recipe[rvm::user]` in your run_list and add a user
hash to the `installs` attribute hash. For example:

    node.set["rvm"]["installs"] = {
      "wigglebottom" => {
        "default_ruby"  => "rbx",
        "rubies"        => ["1.9.2", "1.8.7"]
      }
    }

See below for more details.

### <a name="usage-system"></a> RVM Installed System-Wide and LWRPs Defined

If you want to manage your own RVM environment with the provided [LWRP][lwrp]s,
then include `recipe[rvm::system_install]` in your run_list to prevent
a default RVM Ruby being installed. See the **Resources and Providers**
section for more details.

### <a name="usage-user"></a> RVM Installed For A Specific User and LWRPs Defined

If you want to manage your own RVM environment for users with the provided
LWRPs, then include `recipe[rvm::user_install]` in your run_list and add a
user hash to the `installs` attribute hash. For example:

    node.set["rvm"]["installs"] = {
      "wigglebottom" => true
    }

See the **Resources and Providers** section for more details.

### <a name="usage-minimal"></a> Ultra-Minimal Access To LWRPs

Simply include `recipe[rvm]` in your run_list and the LWRPs will be available
to use in other cookbooks. See the **Resources and Providers** section for
more details.

### <a name="usage-other"></a> Other Use Cases

* If node is running in a Vagrant VM, then including `recipe[rvm::vagrant]`
in your run_list can help with resolving the *chef-solo* binary on subsequent
provision executions.
* If you want other Chef cookbooks to install RubyGems in RVM-managed Rubies,
you can try including `recipe[rvm::gem_package]` in your run_list. Please
read the recipe details before attempting.

## <a name="requirements"></a> Requirements

### <a name="requirements-chef"></a> Chef

Tested on 11.6.0 but newer and older versions (of 10/11)
should work just fine. Due to the `rvm_gem` implementation, versions 0.8.x
of Chef currently will **not** work (see [GH-50][gh50]).

File an [issue][issues] if this isn't the case.

### <a name="requirements-platform"></a> Platform

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

* ubuntu (10.04/10.10/11.04/12.04)
* debian (6.0)
* mac_os_x (10.6/10.7) (See [Platform Notes](#platform-notes-osx))
* mac_os_x_server (See [Platform Notes](#platform-notes-osx))
* suse (openSUSE, SLES)
* centos
* amazon (2011.09)
* scientific
* redhat
* fedora
* gentoo

Please [report][issues] any additional platforms so they can be added.

### Platform Notes

#### <a name="platform-notes-osx"></a> OSX

This cookbook suggests the [homebrew](http://community.opscode.com/cookbooks/homebrew) cookbook, which is needed to install
any additional packages needed to compile ruby. RVM now ships binary rubies,
but will require homebrew to install any additional libraries.

### <a name="requirements-cookbooks"></a> Cookbooks

This cookbook depends on the following external cookbooks:

* [chef\_gem][chef_gem_cb]

If you are installing [JRuby][jruby] then a Java runtime will need to be
installed. The Opscode [java cookbook][java_cb] can be used on supported
platforms.

## <a name="installation"></a> 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][chef_repo] is also assumed.

### <a name="installation-berkshelf"></a> Using Berkshelf

[Berkshelf][berkshelf] is a way to manage a cookbook or an application's
cookbook dependencies. Include the cookbook in your Berksfile, and then run
`berks install`. To install using Berkshelf:

    gem install berkshelf
    cd chef-repo
    berks init
    echo "cookbook 'rvm', github: 'fnichol/chef-rvm'" >> Berksfile
    berks install

### <a name="installation-librarian"></a> Using Librarian-Chef

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

    gem install librarian-chef
    cd chef-repo
    librarian-chef init
    cat >> Cheffile <<END_OF_CHEFFILE
    cookbook 'rvm',
      :git => 'git://github.com/fnichol/chef-rvm.git', :ref => 'v0.9.0'
    END_OF_CHEFFILE
    librarian-chef install

### <a name="installation-kgc"></a> Using knife-github-cookbooks

The [knife-github-cookbooks][kgc] 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-rvm/v0.9.0

### <a name="installation-gitsubmodule"></a> As a Git Submodule

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

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

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

### <a name="installation-tarball"></a> 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-rvm/tarball/v0.9.0 | tar xfz - && \
      mv fnichol-chef-rvm-* rvm

### <a name="installation-platform"></a> From the Opscode Community Platform

This cookbook is not currently available on the site due to the flat
namespace for cookbooks. There is some community work to be done here.

## <a name="recipes"></a> Recipes

### <a name="recipes-default"></a> default

Installs the RVM gem and initializes Chef to use the Lightweight Resources
and Providers ([LWRPs][lwrp]).

Use this recipe explicitly if you only want access to the LWRPs provided.

### <a name="recipes-system-install"></a> system_install

Installs the RVM codebase system-wide (that is, into `/usr/local/rvm`). This
recipe includes *default*.

Use this recipe by itself if you want RVM installed system-wide but want
to handle installing Rubies, invoking LWRPs, etc..

### <a name="recipes-system"></a> system

Installs the RVM codebase system-wide (that is, into `/usr/local/rvm`) and
installs Rubies, global gems, and specific gems driven off attribute metadata.
This recipe includes *default* and *system_install*.

Use this recipe by itself if you want RVM system-wide with Rubies installed,
etc.

### <a name="recipes-user-install"></a> user_install

Installs the RVM codebase for a list of users (selected from the
`node['rvm']['installs']` hash). This recipe includes *default*.

Use this recipe by itself if you want RVM installed for specific users in
isolation but want each user to handle installing Rubies, invoking LWRPs, etc.

### <a name="recipes-user"></a> user

Installs the RVM codebase for a list of users (selected from the
`node['rvm']['installs']` hash) and installs Rubies, global gems, and
specific gems driven off attribute metadata. This recipe includes *default*
and *user_install*.

Use this recipe by itself if you want RVM installed for specific users in
isolation with Rubies installed, etc.

### <a name="recipes-vagrant"></a> vagrant

An optional recipe if Chef is installed in a non-RVM Ruby in a
[Vagrant][vagrant] virtual machine. This recipe adds the default *vagrant*
user to the RVM unix group and installs a `chef-solo` wrapper script so Chef
doesn't need to be re-installed in the default RVM Ruby.

### <a name="recipes-gem-package"></a> gem_package

An experimental recipe that patches the [gem_package resource][gem_package]
to use the `Chef::Provider::Package::RVMRubygems` provider. An attribute
`rvm/gem_package/rvm_string` will determine which RVM Ruby is used for
install/remove/upgrade/purge actions. This may help when using a third
party or upstream cookbook that assumes a non-RVM managed system Ruby.

**Note:** When this recipe is included it will force RVM to be
installed in the [compilation phase][compilation]. This will ensure that all
Rubies can be available if any `gem_package` resource calls are issued from
other cookbooks during the compilation phase.

**Warning:** [Here be dragons][dragons]! This is either brilliant or the
dumbest idea ever, so feedback is appreciated.

## <a name="attributes"></a> Attributes

### <a name="attributes-default-ruby"></a> default_ruby

The default Ruby for RVM installed system-wide. If the RVM Ruby is not
installed, it will be built as a pre-requisite. The value can also contain a
gemset in the form of `"ruby-1.8.7-p352@awesome"`.

The default is `"ruby-1.9.3-p547"`. To disable a default Ruby from being
set, use an empty string (`""`) or a value of `"system"`.

### <a name="attributes-user-default-ruby"></a> user_default_ruby

The default Ruby for RVMs installed per-user when not explicitly set for that
user. If the RVM Ruby is not installed, it will be built as a pre-requisite.
The value can also contain a gemset in the form of `"ruby-1.8.7-p352@awesome"`.

The default is `"ruby-1.9.3-p547"`. To disable a default Ruby from being
set, use an empty string (`""`) or a value of `"system"`.

### <a name="attributes-rubies"></a> rubies

A list of additional RVM system-wide Rubies to be built and installed. This
list does not need to necessarily contain your default Ruby as the
`rvm_default_ruby` resource will take care of installing itself. You may also
include patch info and a rubygems version. For example:

    node['rvm']['rubies'] = [
      "ree-1.8.7",
      "jruby",
      {
        'version' => '1.9.3-p125-perf',
        'patch' => 'falcon',
        'rubygems_version' => '1.5.2'
      }
    ]

The default is an empty array: `[]`.

### <a name="attributes-user-rubies"></a> user_rubies

A list of additional RVM Rubies to be built and installed per-user when not
explicitly set. This list does not need to necessarily contain your default
Ruby as the `rvm_default_ruby` resource will take care of installing itself.
For example:

    node['rvm']['user_rubies'] = [ "ree-1.8.7", "jruby" ]

The default is an empty array: `[]`.

### <a name="attributes-global-gems"></a> global_gems

A list of gem hashes to be installed into the *global* gemset in each
installed RVM Ruby sytem-wide. The **global.gems** files will be added to and
all installed Rubies will be iterated over to ensure full installation
coverage. See the `rvm_gem` resource for more details about the options for
each gem hash.

The default puts bundler and rake in each Ruby:

    node['rvm']['global_gems'] = [
      { 'name'    => 'bundler' },
      { 'name'    => 'rake',
        'version' => '0.9.2'
      },
      { 'name'    => 'rubygems-bundler',
        'action'  => 'remove'
      }
    ]

### <a name="attributes-user-global-gems"></a> user_global_gems

A list of gem hashes to be installed into the *global* gemset in each
installed RVM Ruby for each user when not explicitly set. The
**global.gems** files will be added to and all installed Rubies will be
iterated over to ensure full installation coverage. See the `rvm_gem`
resource for more details about the options for each gem hash.

The default puts bundler and rake in each Ruby:

    node['rvm']['user_global_gems'] = [
      { 'name'    => 'bundler' },
      { 'name'    => 'rake',
        'version' => '0.9.2'
      },
      { 'name'    => 'rubygems-bundler',
        'action'  => 'remove'
      }
    ]

### <a name="attributes-gems"></a> gems

A list of gem hashes to be installed into arbitrary RVM Rubies and gemsets
system-wide. See the `rvm_gem` resource for more details about the options for
each gem hash and target Ruby environment. For example:

    node['rvm']['gems'] = {
      'ruby-1.9.2-p280' => [
        { 'name'    => 'vagrant' },
        { 'name'    => 'veewee' },
        { 'name'    => 'rake',
          'version' => '0.9.2'
        }
      ],
      'ruby-1.9.2-p280@empty-gemset' => [],
      'jruby' => [
        { 'name'    => 'nokogiri',
          'version' => '1.5.0.beta.2'
        },
        { 'name'    => 'warbler' }
      ]
    }

The default is an empty hash: `{}`.

### <a name="attributes-user-gems"></a> user_gems

A list of gem hashes to be installed into arbitrary RVM Rubies and gemsets
for each user when not explicitly set. See the `rvm_gem` resource for more
details about the options for each gem hash and target Ruby environment. See
the `gems` attribute for an example.

The default is an empty hash: `{}`.

### <a name="attributes-rvmrc-env"></a> rvmrc\_env

A hash of system-wide `rvmrc` options. The key is the RVM setting name
(in String or Symbol form) and the value is the desired setting value.
If the value is set to `false` or `nil` then this value will not be
included. An example used on a build box might be:

    node.set['rvm']['rvmrc_env'] = {
      'rvm_project_rvmrc'             => 1,
      'rvm_gemset_create_on_use_flag' => 1,
      'rvm_trust_rvmrcs_flag'         => 1,
      'rvm_gem_options'               => false
    }

The default is: `{ "rvm_gem_options" => "--no-ri --no-rdoc" }`.

### <a name="attributes-installs"></a> installs

A hash of user specific RVM installation hashes. The `user_install` and
`user` recipes use this attribute to determine per-user installation settings.
The hash keys correspond to the default/system equivalents. For example:

    node["rvm"]["installs"] = {
      "jdoe" => {
        "rvmrc_env" => {
          "rvm_gem_options" => false
        },
        "action"          => "force",
        "default_ruby"    => "ree",
        "global_gems"     => [
          { "name"    => "bundler",
            "version" => "1.1.pre.7"
          },
          { "name"    => "rake" }
        ]
      },
      "jenkins" => {
        "installer_flags" => "--version 1.19.0",
        "default_ruby"  => "jruby-1.6.3",
        "rubies" => [
          "ree-1.8.7",
          "jruby",
          {
            "version" => "1.9.3-p125-perf",
            "patch" => "falcon",
            "rubygems_version" => "1.5.2"
          }
        ],
        "rvmrc_env"      => {
          "rvm_project_rvmrc"             => 1,
          "rvm_gemset_create_on_use_flag" => 1,
          "rvm_pretty_print_flag"         => 1
        },
        "global_gems"   => [
          { "name"    => "bundler",
            "version" => "1.1.pre.7"
          },
          { "name"    => "rake",
            "version" => "0.8.7"
          }
        ]
      }
    }

The default is an empty hash: `{}`.

### <a name="attributes-installer-url"></a> installer\_url

The URL that provides the RVM installer.

The default is `"https://get.rvm.io"`.

### <a name="attributes-installer-flags"></a> installer\_flags

The default string of arguments passed to an RVM installation script. The value
will be used as the default flag string for all
[rvm_installation][#resources-rvm-installation] resources.

The default is `"stable"`.

### <a name="attributes-group-id"></a> group_id

The Unix *GID* to be used for the `rvm` group. If this attribute is set,
the group will be created in the compilation phase to avoid any collisions
with expected *GID*s in other cookbooks. If left at the default value,
the RVM installer will create this group as normal.

The default is `default`.

### <a name="attributes-group-users"></a> group_users

A list of users that will be added to the `rvm` group. These users
will then be able to manage RVM in a system-wide installation.

The default is an empty list: `[]`.

### <a name="attributes-gem-package-rvm-string"></a> gem_package/rvm_string

If using the `gem_package` recipe, this determines which Ruby or Rubies will
be used by the `gem_package` resource in other cookbooks. The value can be
either a *String* (for example `ruby-1.8.7-p334`) or an *Array* of RVM Ruby
strings (for example `['ruby-1.8.7-p334', 'system']`). To target an underlying
unmanaged system Ruby you can use `system`.

The default is the value of the `default_ruby` attribute.

### <a name="attributes-vagrant-system-chef-solo"></a> vagrant/system_chef_solo

If using the `vagrant` recipe, this sets the path to the package-installed
*chef-solo* binary.

The default is `"/opt/ruby/bin/chef-solo"`.

usage.

##### Remove Ruby

    rvm_ruby "ree-1.8.7-2011.01" do
      action :remove
    end

**Note:** the RVM documentation mentions that this method is far preferred to
using uninstall since it purges almost everything.

##### Uninstall Ruby

### <a name="lwrps-rvmenvironment"></a> rvm_environment

This resource ensures that the specified RVM Ruby is installed and the optional
gemset is created. It is a convenience resource which wraps `rvm_ruby` and

##### Wrapping A Ruby CLI

    rvm_wrapper "sys" do
      ruby_string   "jruby@utils"
      binary        "thor"
    end

This will create a wrapper script called `sys_thor` in the `bin` directory
under `node['rvm']['root_path']`.

##### Wrapping A List Of Binaries

    rvm_wrapper "test" do
      ruby_string   "default@testing"
      binaries      [ "rspec", "cucumber" ]
      action        :create
