Vulcano CLI

Test your Server, VM, or workstation.

Small example: Write a your checks in test.rb:

describe file('/proc/cpuinfo') do
  it { should be_file }
end

describe ssh_config do
  its('Protocol') { should eq('2') }
end

Run this file locally:

vulcano exec test.rb

Installation

Requires Ruby ( >1.9 ).

To simply run it without installation, you must install bundler:

bundle install
bundle exec bin/vulcano help

To install it as a gem locally, run:

gem build vulcano.gemspec
gem install vulcano-*.gem

You should now be able to run:

vulcano --help

Usage

exec

Run tests against different targets:

# run test locally
vulcano exec test.rb

# run test on remote host on SSH
vulcano exec test.rb -t ssh://user@hostname

# run test on remote windows host on WinRM
vulcano exec test.rb -t winrm://Administrator@windowshost --password 'your-password'

# run test on docker container
vulcano exec test.rb -t docker://container_id

detect

Verify your configuration and detect

id=$( docker run -dti ubuntu:14.04 /bin/bash )
vulcano detect -t docker://$id

Which will provide you with:

{"family":"ubuntu","release":"14.04","arch":null}

Custom resources

You can easily create your own resources. Here is a custom resource for an application called Gordon and save it in gordon_config.rb:

require 'yaml'

class GordonConfig < Vulcano.resource
  name 'gordon_config'

  def initialize
    @path = '/etc/gordon/config.yaml'
    @config = vulcano.file(@path).content
    @params = YAML.load(@config)
  end

  def method_missing(name)
    @params[name.to_s]
  end
end

Include this file in your test.rb:

require_relative 'gordon_config'

Now you can start using your new resource:

describe gordon_config do
  its('Version') { should eq('1.0') }
end

Tests

Runner

Runner tests will make sure the backend execution layer behaves as expected. These tests will take a while, as a lot of different operating systems and configurations are being tested.

You will require:

• vagrant with virtualbox
• test-kitchen
• docker

Run all tests via

rake test:runner

# configure concurrency:
CONCURRENCY=3 rake test:runner

This will go to test/runner and run kitchen test. You can test specific operating systems and configurations via test-kitchen.
