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', gid => allstaff, groups => ['developers', 'operations', 'release'], }, 'dan' => { uid => '1308', gid => allstaff, groups => ['developers', 'prosvc', 'release'], }, } 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. Virtual and Exported resources may be created by prefixing the type name with @ or @@ respectively. For example, the $myusers hash may be exported in the following manner: create_resources("@@user", $myusers) The $myusers may be declared as virtual resources using: create_resources("@user", $myusers) ENDHEREDOC raise ArgumentError, ("create_resources(): wrong number of arguments (#{args.length}; must be 2 or 3)") if args.length > 3 raise ArgumentError, ('create_resources(): second argument must be a hash') unless args[1].is_a?(Hash) if args.length == 3 raise ArgumentError, ('create_resources(): third argument, if provided, must be a hash') unless args[2].is_a?(Hash) end type, instances, defaults = args defaults ||= {} resource = Puppet::Parser::AST::Resource.new(:type => type.sub(/^@{1,2}/, '').downcase, :instances => instances.collect do |title, params| Puppet::Parser::AST::ResourceInstance.new( :title => Puppet::Parser::AST::Leaf.new(:value => title), :parameters => defaults.merge(params).collect do |name, value| Puppet::Parser::AST::ResourceParam.new( :param => name, :value => Puppet::Parser::AST::Leaf.new(:value => value)) end) end) if type.start_with?
