|
||
|
|
Takes a resource type, title, and a list of attributes that describe a
|
||
|
|
resource.
|
||
|
|
|
||
|
|
user { 'dan':
|
||
|
|
ensure => present,
|
||
|
|
}
|
||
|
|
|
||
|
|
This example only creates the resource if it does not already exist:
|
||
|
|
|
||
|
|
ensure_resource('user, 'dan', {'ensure' => 'present' })
|
||
|
|
|
||
|
|
If the resource already exists but does not match the specified parameters,
|
||
|
|
this function will attempt to recreate the resource leading to a duplicate
|
||
|
|
resource definition error.
