ec2-tags Ohai Plugin

An Ohai plugin for getting EC2 instance tags

Install & Usage Instructions

ec2-tags-ohai-plugin

Installation

In order to use this plugin you will need ensure that the following are in your
runlist:
- recipe[ec2-tags-ohai-plugin]

The recipe will install the required aws-sdk gem and the ec2-tags plugin at
compile time, so it is recommended that this is the first recipe in your runlist
so that the node data it creates can be consumed during the rest of the compilation.

Usage

Once the plugin has been installed by the ec2-tags-ohai-plugin recipe,
the instance tags will be available under node['ec2']['tags'] as a hash with
the tag key being the hash key, i.e
ruby
puts node['ec2']['tags']
{
'Name' => 'instance_name',
'my_custom_tag' => 'value'
}


The instances will need to have an IAM instance profile that allows at least
the EC2 DescribeTags endpoint to be called.
