Serverspec init

サーバーテストツール
http://serverspec.org/resource_types.html

With Serverspec, you can write RSpec tests for checking your servers are configured correctly.
Serverspec tests your servers’ actual state by executing command locally, via SSH, via WinRM, via Docker API and so on. So you don’t need to install any agent softwares on your servers and can use any configuration management tools, Puppet, Ansible, CFEngine, Itamae and so on.

vagrant fileをつくり、サーバーを二つ起動します。

    node.vm.box = "bento/centos-6.7"
    node.vm.hostname = "host"
    node.vm.network :private_network, ip: "192.168.33.13"
