This function takes two mandatory arguments: a resource type, and a hash describing a set of resources. The hash should be in the form `{title => {parameters} }`: # A hash of user resources: $myusers = { 'nick' => { uid => '1330', group => allstaff, groups => ['developers', 'operations', 'release'], } 'dan' => { uid => '1308', group => allstaff, groups => ['developers', 'prosvc', 'release'], } } - create_resource(user, $myusers) + create_resources(user, $myusers) A third, optional parameter may be given, also as a hash: $defaults => { 'ensure' => present, 'provider' => 'ldap', } create_resources(user, $myusers, $defaults) The values given on the third argument are added to the parameters of each resource present in the set given on the second argument. If a parameter is present on both the second and third arguments, the one on the second argument takes precedence. This function can be used to create defined resources and classes, as well as native resources.
