Manages system-wide and per-user RVMs and manages installed Rubies. Several lightweight resources and providers (LWRP) are also defined.
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.
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 user_installs
attribute list. For example:
node['rvm']['user_installs'] = [
{ 'user' => 'wigglebottom',
'default_ruby' => 'rbx',
'rubies' => ['1.9.2', '1.8.7']
}
]
See below for more details.
If you want to manage your own RVM environment with the provided LWRPs,
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.
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 user_installs
attribute list. For example:
node['rvm']['user_installs'] = [
{ 'user' => 'wigglebottom' }
]
See the Resources and Providers section for more details.
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.
- 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.
Tested on 0.10.2/0.10.4 and 0.9.16 but newer and older versions (of 0.9.x)
should work just fine. Due to the rvm_gem
implementation, versions 0.8.x
of Chef currently will not work (see GH-50).
File an issue if this isn't the case.
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)
- mac_os_x_server (See Platform Notes)
- suse (openSUSE, SLES)
- centos
- amazon (2011.09)
- scientific
- redhat
- fedora
Please report any additional platforms so they can be added.
This cookbook suggests the 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.
This cookbook depends on the following external cookbooks:
If you are installing JRuby then a Java runtime will need to be installed. The Opscode java cookbook can be used on supported platforms.
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.
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
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
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
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-rvm/v0.9.0
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.
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
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.
Installs the RVM gem and initializes Chef to use the Lightweight Resources and Providers (LWRPs).
Use this recipe explicitly if you only want access to the LWRPs provided.
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..
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.
Installs the RVM codebase for a list of users (selected from the
node['rvm']['user_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.
Installs the RVM codebase for a list of users (selected from the
node['rvm']['user_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.
An optional recipe if Chef is installed in a non-RVM Ruby in a
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.
An experimental recipe that patches the gem_package resource
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. 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! This is either brilliant or the dumbest idea ever, so feedback is appreciated.
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-2.0.0-p0"
. To disable a default Ruby from being
set, use an empty string (""
) or a value of "system"
.
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-2.0.0-p0"
. To disable a default Ruby from being
set, use an empty string (""
) or a value of "system"
.
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 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 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 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 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 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 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.
An example used on a build box might be:
node['rvm']['rvmrc'] = {
'rvm_project_rvmrc' => 1,
'rvm_gemset_create_on_use_flag' => 1,
'rvm_trust_rvmrcs_flag' => 1
}
The default is an empty hash: {}
.
A list 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']['user_installs'] = [
{ 'user' => 'jdoe',
'upgrade' => "head",
'default_ruby' => 'ree',
'rvm_gem_options' => "",
'global_gems' => [
{ 'name' => 'bundler',
'version' => '1.1.pre.7'
},
{ 'name' => 'rake' },
{ 'name' => 'rubygems-bundler',
'action' => 'remove'
}
]
},
{ 'user' => 'jenkins',
'version' => '1.7.0',
'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' => {
'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'
},
{ 'name' => 'rubygems-bundler',
'action' => 'remove'
}
]
}
]
The default is an empty list: []
.
The URL that provides the RVM installer.
The default is "https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer"
.
A specific git branch to use when installing system-wide. For example:
node['rvm']['branch'] = "crazy"
The default is "stable"
which corresponds to the stable release branch.
A specific tagged version or head of a branch to use when installing
system-wide. This value is passed directly to the rvm-installer
script and
current valid values are:
"head"
- the default, last git commit on a branch- a specific tagged version of the form
"1.2.3"
.
You may want to use a specific version of RVM to prevent differences in deployment from one day to the next (RVM head moves pretty darn quickly).
Note that if a version number is used, then "none"
should be the value
of the branch
attribute. For example:
node['rvm']['version'] = "1.13.4"
node['rvm']['branch'] = "none"
The default is "head"
.
Determines how to handle installing updates to the RVM framework system-wide.
The value of this string is passed to rvm get
. The possible values include:
"none"
,false
, ornil
: will not update RVM and leave it in its current state.- Any other value is passed to
rvm get
as described on the upgrading page. For example:"latest"
,"stable"
, and"branch mpapis/shoes"
.
The default is "none"
.
The path prefix to RVM in a system-wide installation.
The default is "/usr/local/rvm"
.
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 GIDs in other cookbooks. If left at the default value,
the RVM installer will create this group as normal.
The default is default
.
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: []
.
These options are passed to the gem command in an RVM environment. In the interest of speed, rdoc and ri docs will not be generated by default. To re-enable the documentation generation set:
node['rvm']['rvm_gem_options'] = "--rdoc --ri"
The default is "--no-rdoc --no-ri"
.
Can enable or disable installation of a default Ruby and additional Rubies system-wide. For example:
node['rvm']['install_rubies'] = "false"
The default is "true"
.
Note: This remains a legacy setting and will be deprecated in the next minor version release.
Can enable or disable installation of a default Ruby and additional Rubies per user. For example:
node['rvm']['user_install_rubies'] = "false"
The default is "true"
.
Note: This remains a legacy setting and will be deprecated in the next minor version release.
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.
If using the vagrant
recipe, this sets the path to the package-installed
chef-solo binary.
The default is "/opt/ruby/bin/chef-solo"
.
