scalr cookbook

A library to access Scalr Global Variables using the local Scalr agent, szradm.

Requirements

Add the Scalr cookbook to your dependencies. In metadata.rb:

depends 'scalr', '~> 0.2.0'

Make sure the Scalr cookbook is available on your node. If you're using a Berksfile to manage your recipe, you can add:

cookbook 'scalr', git: 'https://github.com/scalr-tutorials/scalr-cookbook.git'

Usage

In your recipes, providers and resources, use:

Scalr.global_variables

This will return a Hash of your Global Variables.

If szradm is not available in your development environment, you can override Global Variables using attributes.

To do this, update your call to Scalr.global_variables to include the node:

Scalr.global_variables node

And then define the attributes (see below).

Attributes

Set default[:scalr][:override_gv] to a Hash, and you'll be served those variables instead of Scalr's Global Variables.

If this attribute is defined, the library will not hit szradm.
