basic heat examples
##- first.yaml
Creates a network
##- Second.yaml
Creates an instance on the private network, this network should be already created
##- Third.yaml
demostratrs how to execute scrips inside the deployed image using os-collect-config. It also demostrates how to create a glance image with the required software

An OS::Heat::SoftwareConfig resource - this encapsulates the config to be applied, e.g a script, puppet manifest, or any other config definition format you care to use. This is just a wrapper for the config to apply, optionally parameterized with input values, it doesn't actually configure anything.
An OS::Heat::SoftwareDeployment resource - this is the thing which actually applies the config from (1) - when it moves to and IN_PROGRESS state, it makes the config available to the specified server. By default, the deployment will stay in the IN_PROGRESS state until a signal is received via the Heat API, notifying the service of success (or failure..) applying the config.
An OS::Nova::Server resource - this is the instance (or physical server in the case of TripleO deploying via Nova and Ironic) being configured, it must contain some tools to support SoftwareConfig, as discussed below, and define the user_data_format property to enable SoftwareConfig.
##- Forth.yaml
Dermodtrates how execute scripts inside the deployed instance usiung cloud-init
as you cansee, the script is not a resource, its a parameter
