Linode Ruby API

INSTALLATION:

Make sure gemcutter.org is in your gem sources list, then:

 % sudo gem install linode

To run tests you will need both rspec and mocha installed.

RUNNING:

Consult the Linode API guide here: http://www.linode.com/api/autodoc.cfm
You will need to get an API key (check your account profile).

Here is an annoyingly exhaustive IRB session where I play around with the API:

irb> require 'rubygems'
irb> require 'linode'
irb> api_key = 'TOPSECRETAPIKEY'
irb> l = Linode.new(:api_key => api_key)
=> #<Linode:0x100e03c @api_key="TOPSECRETAPIKEY">

irb> result = l.test.echo(:foo => 'bar', :baz => 'xyzzy')
=> #<OpenStruct baz="xyzzy", foo="bar">
irb> result.foo
=> "bar"

irb> result.baz
=> "xyzzy"

irb> result = l.avail.datacenters
=> [#<OpenStruct datacenterid=2, location="Dallas, TX, USA">, #<OpenStruct datacenterid=3, location="Fremont, CA, USA">, #<OpenStruct datacenterid=4, location="Atlanta, GA, USA">, #<OpenStruct datacenterid=6, location="Newark, NJ, USA">]
irb> s = _

irb> result.first
=> #<OpenStruct datacenterid=2, location="Dallas, TX, USA">
irb> result.first.location
=> "Dallas, TX, USA"
irb> l.avail.datacenters.collect {|i| i.location }

irb> l.avail.datacenters.collect {|i| i.datacenterid }
