Kevin Carter 271ff6a09c Add project directory to overlay inventories 
The use of an overlay inventory has now been added to a stand alone
directory which should help deployers understand how this could work
within their environments. Inventory configuration has been updated to
show this working in the various projects that have tests and could
benefit from an overlay inventory.

Overlay Ansible inventories

To deploy any of the operational tooling within an existing OpenStack-Ansible deployment environment, or any environment that is using Ansible, it's possible to use an overlay inventory to deploy systems without having to make configuration changes in an environment or it's given inventory.

An overlay inventory is nothing more than a second inventory source which contains meta groups that reference other groups as children.

This project folder contains reference overlay inventories that can be used to deploy all of the tested operational tooling.

####### What's currently included

  • elk_metrics_6x
  • grafana
  • osquery
  • skydive

Deploying | The environment

The example overlay inventory file osa-integration-inventory.yml in this directory is being used in this example to deploy all of the operational tooling in an already online OpenStack-Ansible deployed cloud.

The use of overlay inventories requires modern versions of Ansible. In this deployment example the embedded Ansible solution is being used to ensure all of the requirements are met.
