Paratrooper-chef

A capistrano recipe to execute chef-solo in each server. All of you can use chef-solo remotely without chef-server.

Installation

Add this line to your application's Gemfile:

gem 'capistrano-paratrooper-chef'

And then execute:

$ bundle

Or install it yourself as:

$ gem install capistrano-paratrooper-chef

Usage

This recipe will execute chef-solo through paratrooper:chef task.

To setup paratrooper-chef for your application, add following in you config/deploy.rb.

# in "config/deploy.rb"
require 'capistrano-paratrooper-chef'

And then, put your chef-kitchen files to config/ directory. by default, paratrooper-chef uses following files and directories.

  • config/Berksfile
  • config/Cheffile
  • config/solo.rb
  • config/site-cookbooks
  • config/roles
  • config/environments
  • config/data_bags
  • config/data_bag_key

Finally, run capistrano with paratrooper:chef task. Then chef-solo runs at remote host.

$ cap paratrooper:chef

Setup chef-solo to remote hosts

Paratrooper-chef includes another task to setup chef-solo to remote hosts. To enable it, add following in your config/deploy.rb.

# in "config/deploy.rb"
require "capistrano-paratrooper-chef/omnibus_install"

This recipe will install chef-solo using omnibus-installer during deploy:setup task.

Another way, you want to install chef-solo as gem package, use following lines.

# in "config/deploy.rb"
require "capistrano-paratrooper-chef/install"

This recipe will install chef-solo using gem command during deploy:setup task. Of cource, capistrano-paratrooper-chef/install requires ruby and rubygems are available.

Define attributes for specific host

Paratrooper-chef supports switching attributes for each host. Put definition to config/nodes/#{hostname}.json.

If there are no defitions for host, paratrooper-chef uses config/solo.rb as attributes.

Chef roles Auto discovery

Chef roles auto discovery appends roles of chef to run_list of each host. To enable auto discovery, set :chef_roles_auto_discovery true (as defualt, it is disabled).

# in "config/deploy.rb"
set :chef_roles_auto_discovery, true

This feature makes name-based relations with role of capistrano and chef's one::

  • Discovering role definitions of chef from role-names of capistrano that server is assigned
  • Run chef with discovered roles at each server
  • Be able to play different roles of chef for each server

For example, 'web.example.com' plays :web role:

set :web, 'web.example.com'

And, there is role defition named 'web.json'.

# config/roles/web.json
{
  "nginx" : {
    # ...
  },
  "run_list" : [
    "recipe[nginx]",
  }
}

Then, paratrooper-chef detects automatically these relation, and append 'role[web]' to run_list of web.example.com . (do not effect to other hosts)
