函數參考-人偶中的create_resources

Question

請參閱https://docs.puppetlabs.com/references/latest/function.html#createresources

# 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)

閱讀此函數的說明create_resources ，但不確定在create_resources(user, $myusers)之后會create_resources(user, $myusers)什么結果

它是否使用指定的uid，gid和groups創建兩個用戶nick和dan ？

更新：

網絡上的一些解釋。

Listing 12-79. Hiera lookup of sysadmin hash
root@puppet-master-hiera-ubuntu:/etc/puppet/data# hiera sysadmins
{"spencer"=>{"uid"=>1861, "groups"=>"root", "gid"=>300}, "william"=>{"uid"=>11254,
"groups"=>"root", "gid"=>300}}

   Now we can use a function called create_resources() to generate Puppet resources from this hash, as shown in

Listing 12-80. create_resources example

$sysadmins = hiera('sysadmins')

create_resources(user, $sysadmins)

    Listing 12-81 shows the output.

Listing 12-81. Applying the create_resources example from Listing 12-80

root@puppet-master-hiera-ubuntu:/etc/puppet# puppet apply create_resources.pp
Notice: Compiled catalog for puppet-master-hiera-ubuntu.green.gah in environment production in
0.11 seconds
Notice: /User[spencer]/ensure: created
Notice: /User[william]/ensure: created
Notice: Finished catalog run in 0.32 seconds

我無法在我的環境中正確設置和證明它，但是上面的示例給出了答案，它確實在create_resources函數中使用哈希創建用戶帳戶。

Answer 1

create_resources只會映射

# 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)

成

  user{'nick':
    uid    => '1330',
    gid    => allstaff,
    groups => ['developers', 'operations', 'release'], },
  }
  user{'dan':
    uid    => '1308',
    gid    => allstaff,
    groups => ['developers', 'prosvc', 'release'], },
  }

因此，這些用戶將被傳遞給用戶提供者。 您可以使用配方輕松地對其進行測試，以創建一個users.pp文件，並使用puppet apply --noop對其進行測試：

# puppet apply --noop users.pp 
Notice: Compiled catalog for yourfqdn in environment production in 0.15 seconds
Notice: /Stage[main]/Main/User[nick]/ensure: current_value absent, should be present (noop)
Notice: /Stage[main]/Main/User[dan]/ensure: current_value absent, should be present (noop)

請注意，如果用戶已經存在，puppet apply不會做任何事情
