ServerSpec Notes

These are snippets of auto-generated from ServerSpec. The serverspec-init only auto-generates base functionality with cmd, exec, ssh, and winrm backends with some optional vagrant support for dyanmic inventory on ssh backend.

There are additional backends available from SpecInfra, but these are not supported and only documented in O'Reilly book for Serverspec: The Definitive Guide by Gosuke Miyashita (ISBN978-4-87311-709-6), which is in Japanese only:

Spec Helper

Windows CMD

require 'serverspec'
set :backend, :cmd

Unix Exec

require 'serverspec'
set :backend, :exec

Windows WinRM

require 'serverspec'
require 'winrm'

set :backend, :winrm

user = <username>
pass = <password>
endpoint = "http://#{ENV['TARGET_HOST']}:5985/wsman"

winrm = ::WinRM::WinRMWebService.new(endpoint, :ssl, :user => user, :pass => pass, :basic_auth_only => true)
winrm.set_timeout 300 # 5 minutes max timeout for any operation
Specinfra.configuration.winrm = winrm

SSH w/o Vagrant

require 'serverspec'
require 'net/ssh'

set :backend, :ssh

if ENV['ASK_SUDO_PASSWORD']
  begin
    require 'highline/import'
  rescue LoadError
    fail "highline is not available. Try installing it."
  end
  set :sudo_password, ask("Enter sudo password: ") { |q| q.echo = false }
else
  set :sudo_password, ENV['SUDO_PASSWORD']
end

host = ENV['TARGET_HOST']

options = Net::SSH::Config.for(host)

options[:user] ||= Etc.getlogin

set :host,        options[:host_name] || host
set :ssh_options, options

SSH w Vagrant

require 'serverspec'
require 'net/ssh'
require 'tempfile'

set :backend, :ssh

if ENV['ASK_SUDO_PASSWORD']
  begin
    require 'highline/import'
  rescue LoadError
    fail "highline is not available. Try installing it."
  end
  set :sudo_password, ask("Enter sudo password: ") { |q| q.echo = false }
else
  set :sudo_password, ENV['SUDO_PASSWORD']
end

host = ENV['TARGET_HOST']

`vagrant up #{host}`

config = Tempfile.new('', Dir.tmpdir)
config.write(`vagrant ssh-config #{host}`)
config.close

options = Net::SSH::Config.for(host, [config.path])

options[:user] ||= Etc.getlogin

set :host,        options[:host_name] || host
set :ssh_options, options

SSH Unused Options (Default)

set :disable_sudo, true
set :env, :LANG => 'C', :LC_MESSAGES => 'C'
set :path, '/sbin:/usr/local/sbin:$PATH'
