## Setup
### Setup Requirements
This module assumes nodes running Ubuntu 14.04 (Trusty) with either Puppet Enterprise or Puppet.
More information related to the setup requirement are available in the present guide [Setup requirements](https://support.ba.infn.it/redmine/projects/automaticocp/wiki/TestbedPuppet)
More information related to the setup requirements are available in the following guide - [Setup requirements](https://support.ba.infn.it/redmine/projects/automaticocp/wiki/TestbedPuppet)
This module depends on Hiera.
### Beginning with iaas module
To ensure high availability, three Service nodes, three Storage nodes, two Controller nodes and two Network nodes must be deployed, be sure to have ten available servers. In addition, a number of Compute nodes are also to be available for the deployment.
To ensure high availability of the infrastructure, three Service nodes, three Storage nodes, two Controller nodes and two Network nodes must be deployed. Please make sure you have available at least ten servers.
In addition, a number of Compute nodes must also to be available for the deployment.
The present module supports multiple external networks.
## Usage
The nodes should be deployed in the following order: Service nodes, Storage nodes, Controller nodes, Network nodes and then Compute nodes.
The nodes should be deployed in the following order(USARE ordered-list): Service nodes, Storage nodes, Controller nodes, Network nodes and then Compute nodes.
### Hiera Configuration
The first step to using the iaas module is to configure hiera with specific settings pointing to your installation.
In this module, the `examples` directory contains sample 'common.yaml' file with all of the settings required by this module.
Before using the module you need to collect all the inforamtion regarding your infrastructure: (unordered list) - hostnames, networks (admin, management, data..etc), ...
The first step in using the iaas module is to configure Hiera with the specific settings of your infrastructure.
You can find in the `examples/` directory a sample 'common.yaml' file with all of the settings required by the module.
These configuration options include Service settings, Storage settings, Network settings, OpenStack core settings and related passwords.
If any of these settings are undefined or not properly set, your deployment may fail.
### Site configuration
The second step to using the iaas module is to configure manifest file with specific settings pointing to your installation.
The second step is to configure the manifest file with specific settings pointing to your installation.
In this module, the `examples` directory contains sample 'site.pp' file according to your deployment.
These configuration options include Service variables and node-specific configuration settings.
If any of these settings are undefined or not properly set, your deployment may fail.
