Moonshine Multi Server

A plugin for Moonshine

A plugin for deploying one application to multiple servers

Instructions

• Install the Moonshine
• Configure servers for capistrano setting the appropriate role(s). Here is an example config/deploy.rb:

  server 'web.example.com', :web, :primary => true
  server 'app.example.com', :app, :primary => true
  server 'db.example.com', :db, :primary => true

• Install the Moonshine Multi Server plugin:

Rails 2: script/plugin install https://github.com/railsmachine/moonshine_multi_server.git
Rails 3: script/rails plugin install https://github.com/railsmachine/moonshine_multi_server.git

• After the plugin is installed, generate some manifests!

Rails 2: script/generate moonshine:multi_server web app db
Rails 3: script/rails generate moonshine:multi_server web app db

• create a manifest for each role:
  • app/manifests/application_manifest_.rb
  • app/manifests/database_manifest_.rb
  • app/manifests/web_manifest_.rb
• Add the stacks you need to each manifest. Here is an example app/manifests/application_manifest.rb:

require "#{File.dirname(__FILE__)}/../../vendor/plugins/moonshine/lib/moonshine.rb"
class ApplicationManifest < Moonshine::Manifest::Rails
  include Moonshine::MultiServer
  recipe :standalone_application_stack
end

• Add one bit to your capistrano config/deploy.rb

namespace :moonshine do
  task :apply do
    moonshine.multi_server_apply
  end  
end

TODO

• Document MySQL allowed hosts
• Document *_servers helpers
• More thorough examples
• Examples with having more than app,web,db roles
• Generator?!
• script/generate moonshine_multi_server app web db util
• build capistrano servers from *_servers datas
