Application definition

Application definitions look a lot like a defined resource, but are also similar to a traditional Puppet profile. They describe a collection of components that make an entire system, but unlike profiles, are not tied down to a single node. These application definitions describe a configured state of one or more nodes, broken down by application components. 

 

 

Application definitions will resemble defined types, with a few key differences:

• They are titled application instead of define.
• Each resource must be name spaced within the module:

# Application used instead of 'class' or 'define'
application 'example' (
  $var,
) {

# app1 exports its database configuration items
  example::app1 {
    config => $var,
    export => Database['app1'],
  }

# app2 both imports the previous database and exports its own type: Application
  example::app2 {
    config  => $var,
    consume => Database['app1'],
    export  => Application['app1'],
  }
