Squall

A Ruby library for working with the OnApp REST API.

Squall has been tested on MRI versions 1.9.3, 2.0.0, 2.1.2 and 1.9-compatible JRuby.

Documentation is available in TomDoc format.

Install

To install Squall using Bundler:

echo "gem 'squall'" >> Gemfile
bundle install

To install Squall globally using RubyGems:

gem install squall

Configuration

You have two main options for configuring Squall.

Directly in a config block:

require 'squall'

Squall.config do |c|
  c.base_uri 'https://onappurl.com' # Root level URI for OnApp instance
  c.username 'username'             # OnApp username
  c.password 'topsecret'            # OnApp password
  c.debug     true                  # Toggle HTTP/Faraday debugging (prints to $stderr)
end

Squall can load configuration from a yaml file:

# .squall.yml
base_uri: 'https://onappurl.com'
username: 'username'
password: 'topsecret'
debug: false

To load it (by default it assumes ~/.squall.yml):

Squall.config_file("/path/to/.squall.yml")

It is also possible to change individual configuration settings on the fly.

Squall.configuration.debug(true)

Note: you will need to re-instantiate all modules after changing Squall's configuration.

Usage

Show the info for a VM:

vm = Squall::VirtualMachine.new
vm.show 1

Create a new VM:

vm = Squall::VirtualMachine.new

params = {
  label:             'testmachine',
  hypervisor_id:     5,
  hostname:          'testmachine',
  memory:            512,
  cpus:              1,
  cpu_shares:        10,
  primary_disk_size: 10,
  template_id:       1
}

vm.create params

Supported Methods

This gem partially implements the OnApp API v2.3.

The following OnApp modules have been added:

• Data store zones
• Firewall rules
• Hypervisors
• Hypervisor zones
• IP addresses
• IP address joins
• Networks
• Network zones
• Users
• User groups
• Roles
• Statistics
• Templates
• Transactions
• Virtual machines
• Whitelists
• Disks

The following still need to be added:

• Billing plans
• Currencies
• Network interfaces
• Template groups
• Software licenses
• Resolvers
• VM autoscaling
• Load Balancers
• CDN edge servers
• CDN resources
• CDN edge groups
• Backups
• Autobackup Presets
• Schedules
• SSH keys
• Alerts
• Logs
• System configuration

Tests

Squall uses rspec for tests. To run:

bundle exec rake # Runs all tests
bundle exec rspec spec/squall/[module]_spec.rb # Runs tests for a specific module

Squall uses VCR to cache server responses to test against. To test via live http connections, pass RERECORD=1 into test command. NOTE: since OnApp does not currently support a test environment this is not recommended unless you know what you're doing, as it will destroy live data!

Known issues:

1. VirtualMachine#change_user currently breaks the parser on an invalid user_id because OnApp returns html instead of JSON
2. VirtualMachine#create is currently broken in certain cases.
3. FirewallRule#edit and #create break the parser by returning invalid JSON

Note on Patches/Pull Requests

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
