README

Role Name
=========

A brief description of the role goes here.
The role **ocp-inventory** generates an OpenShift installation inventory using custom variables.
It can be invoked direectly by bastion hosts before deployment of nodes.

Requirements
------------

Since the role is a simple inventory file generator, no specific requirements are needed.

Role Variables
--------------

The inventory customization is all based on role variables. This is an easier approach than polulating all the
inventory from scratch since most of them are simple booleans that enable/disable features.
Some further tuning of the generated inventory file could be needed after running the playbook.

Example Playbooks
----------------

Including some example of how to use the role for single master or multi master deployments.
Playbook with prompted variables can be implemented using vars_prompt.
**IMPORTANT**: single and double quotes used in node labels must be escaped.
