A Chef cookbook to provide a unified interface for installing Ruby and running things with it. This README covers the 2.x version of the cookbook, the 1.x version is very different and no longer supported.
To install the latest available version of Ruby 2.x and then use it to install some gems:
ruby_runtime '2'
ruby_gem 'rake'
bundle_install '/path/to/Gemfile' do
without 'development'
deployment true
end
Chef 12 or newer is required.
Attributes are used to configure the default recipe.
node['poise-ruby']['install_ruby']
– Install a Ruby runtime. (default: true)node['poise-ruby']['install_chef_ruby']
– Create aruby_runtime
using the:chef
provider. Doesn't actually install anything. (default: true)
The default recipe installs Ruby based on the node attributes. It is entirely
optional and can be ignored in favor of direct use of the ruby_runtime
resource.
The ruby_runtime
resource installs a Ruby interpreter.
ruby_runtime 'any' do
version ''
end
:install
– Install the Ruby interpreter. (default):uninstall
– Uninstall the Ruby interpreter.
version
– Version of Ruby to install. If a partial version is given, use the latest available version matching that prefix. (name properties)
The poise-ruby
library offers an additional way to pass configuration
information to the final provider called "options". Options are key/value pairs
that are passed down to the ruby_runtime provider and can be used to control how it
installs Ruby. These can be set in the ruby_runtime
resource using the options
method, in node attributes or via the
ruby_runtime_options
resource. The options from all sources are merged
together in to a single hash.
When setting options in the resource you can either set them for all providers:
ruby_runtime 'myapp' do
version '2.1'
options dev_package: false
end
or for a single provider:
ruby_runtime 'myapp' do
version '2.1'
options :system, dev_package: false
end
Setting via node attributes is generally how an end-user or application cookbook will set options to customize installations in the library cookbooks they are using. You can set options for all installations or for a single runtime:
# Global, for all installations.
override['poise-ruby']['options']['dev_package'] = false
# Single installation.
override['poise-ruby']['myapp']['version'] = '2.2'
The ruby_runtime_options
resource is also available to set node attributes
for a specific installation in a DSL-friendly way:
ruby_runtime_options 'myapp' do
version '2.2'
end
Unlike resource attributes, provider options can be different for each provider. Not all providers support the same options so make sure to the check the documentation for each provider to see what options the use.
The ruby_runtime_options
resource allows setting provider options in a
DSL-friendly way. See the Provider Options section for more
information about provider options overall.
ruby_runtime_options 'myapp' do
version '2.2'
end
:run
– Apply the provider options. (default)
resource
– Name of theruby_runtime
resource. (name property)for_provider
– Provider to set options for.
All other property keys will be used as options data.
The ruby_execute
resource executes a Ruby script using the configured runtime.
ruby_execute 'myapp.rb' do
user 'myuser'
end
This uses the built-in execute
resource and supports all the same properties.
:run
– Execute the script. (default)
command
– Script and arguments to run. Must not include theruby
. (name property)ruby
– Name of theruby_runtime
resource to use. If not specified, the most recently declaredruby_runtime
will be used.
For other properties see the Chef documentation.
The ruby_gem
resource is a subclass of the standard gem_package
resource to
install the gem with the configured runtime.
ruby_gem 'rake' do
version ' 10.4.2'
end
All actions and attributes match the standard gem_package
resource with the
addition of a ruby
attribute matching ruby_execute
.
The bundle_install
resource installs gems based on a Gemfile using
bundler.
bundle_install '/path/to/Gemfile' do
deployment true
jobs 3
end
The underlying bundle
command will run on every converge, but notifications
will only be triggered if a gem is actually installed.
:install
– Runbundle install
. (default):update
– Runbundle update
.
path
– Path to a Gemfile or a directory containing a Gemfile. (name property)binstubs
– Enable binstubs. If set to a string it is the path to generate stubs in.bundler_version
– Version of bundler to install. If unset the latest version is used.deployment
– Enable deployment mode.gem_binary
– Path to the gem binary. If unset this uses theruby_runtime
parent.jobs
– Number of parallel installations to run.retry
– Number of times to retry failed installations.ruby
– Name of theruby_runtime
resource to execute against.user
– User to run bundler as.vendor
– Enable local vendoring. This maps to the--path
option in bundler, but that attribute name is already used.without
– Group or groups to not install.
The system
provider installs Ruby using system packages. This is currently
only tested on platforms using apt-get
and yum
(Debian, Ubuntu, RHEL, CentOS
Amazon Linux, and Fedora) and is the default provider on those platforms. It
may work on other platforms but is untested.
ruby_runtime 'myapp' do
provider :system
version '2.1'
end
dev_package
– Install the package with the headers and other development files. (default: true)rubygems_package
– Install rubygems from a package. This is only needed for Ruby 1.8. (default: true on RHEL 6)package_name
– Override auto-detection of the package name.package_upgrade
– Install using action:upgrade
. (default: false)package_version
– Override auto-detection of the package version.version
– Override the Ruby version.
The chef
provider uses the Ruby environment included in the Omnibus packages.
Great care should be taken when using this provider.
ruby_runtime 'myapp' do
provider :chef
version '2.1'
end
version
– Override the Ruby version.
The ruby_build
provider uses ruby-build
to compile and install Ruby. It can be found in the
poise-ruby-build cookbook.
