Why?

Current version of Ansible (1.7.1) does not merge hashes in the include_vars task even if told so via hash_behaviour = merge in your ansible.cfg. ansible/ansible#9116

This action plugin will merge hashes no matter how you have configured your hash_behaviour.

How to setup:

Save include_vars_merged.py to library/plugins/action/include_vars_merged.py

Save include_vars_merged to library/custom/include_vars_merged

Terraform, CoreOS, and Digital Ocean

Let's use Terraform to easily get a CoreOS cluster up on Digital Ocean. In this example we will get a 5 node CoreOS cluster up and running on the Digital Ocean 8GB size.

Install Terraform

Grab a copy of Terraform for your platform from http://www.terraform.io/downloads.html. Follow the instructions at http://www.terraform.io/intro/getting-started/install.html by getting Terraform in your PATH and testing that it works.
