Lee Hambley c344bc40b2 Enable filtering server list when querying. 
This patch makes it possible to do something like:

    server 'example.com', some_property: true
    on(:all, filter: :some_property) do |h|
      # ...
    end

This is the shorthand syntax which checks the host properties for anything
truthy matching the key name given. Symbols and strings are supported here.

If a more complex match should be made, then a continuation can be given in
the place of the smybol:

    server 'example.com', some_property: true
    on(:all, filter: lambda { |h| h.properties.some_property }) do |h|
      # ...
    end

The keys `filter` and `select` are aliases of one another. Either may be used
interchangably.

An execption is raised if the filter removes all matching servers.

Add this line to your application's Gemfile:

gem 'capistrano', github: 'capistrano/capistrano', branch: :v3

And then execute:

$ bundle --binstubs

Capify:

$ cap install

This creates the following files:

  • config/deploy/production.rb

To create different stages:

$ cap install STAGES=local,sandbox,qa,production

Usage

$ cap -vT

$ cap staging deploy
$ cap production deploy

$ cap production deploy --dry-run
$ cap production deploy --prereqs
$ cap production deploy --trace

Configuration

# config/deploy.rb
set :application, 'example app'

# config/deploy/production.rb
set :stage, :production

ask :branch, :master

role :app, %w{example.com example2.com}
role :web, %w{example.com}
role :db, %w{example.com}

# the first server in the array is considered primary
