vagrant

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "ubuntu-12.04-x64"
  config.omnibus.chef_version = "11.6.0"

  end
end

cookbook(apt-get update)

site-cookbooks/apt_get_update/recipe/default.rb
log "start update apt-get"
execute "update package index" do
  command "apt-get update"
end.run_action(:run)
log "end   update apt-get"

cookbook(jenkins-tomcat)

site-cookbooks/jenkins_tomcat/files/default/jenkins.xml

※デフォルトでjenkins-tomcat packageが作成する内容に加えて
Contextタグにreloadable="true"属性を追加している。
これにより、warが最新化されると自動で再デプロイされる。
