試した手順

1. 環境構築

1. ひな形作成

$ capify .

1. deploy.rb修正

$ vi config/deploy.rb
# 以下の内容を記述
set :application, "hoge"
set :user, "ec2-user"
#set :password, "hoge"

ssh_options[:keys] = %w(/home/hoge/.ssh/key.pem)
ssh_options[:auth_methods] = %w(publickey)

# socks5プロキシを使う場合
#require 'net/ssh/proxy/socks5'
#sshproxy = Net::SSH::Proxy::SOCKS5.new('hoge', 
#                                       1080,

#                                       :password => 'hoge')
#ssh_options[:proxy] = sshproxy

role :ec2, "XXX.compute.amazonaws.com"

task :hw, :roles => [:ec2] do
  run "echo HelloWorld! $HOSTNAME"
end
