Hiera价值无法以木偶轮廓接收

Question

1. 我创建了一个proxy_match.yaml文件作为默认hiera datalocation一个hiera源文件。
2. 该proxy_match.yaml在hiera层次添加
3. 仰望hiera轮廓数据

在哪里，我在想什么，我不能够接收hiera数据值，因此出现错误提到波纹管。

其中，proxy_match是创造了新的环境

hierafile 1个/etc/puppetlabs/code/environments/proxy_match/hiera.yaml

version: 5
defaults:
  # The default value for "datadir" is "data" under the same directory as the hiera.yaml
  # file (this file)
  # When specifying a datadir, make sure the directory exists.
  # See https://docs.puppet.com/puppet/latest/environments.html for further details on environments.
  # datadir: data
  # data_hash: yaml_data


hierarchy:
  - name: "environment specific yaml"
    path: "proxy_match.yaml"
  - name: "Per-node data (yaml version)"
    path: "nodes/%{::trusted.certname}.yaml"
  - name: "Other YAML hierarchy levels"
    paths:
      - "common.yaml"

proxy_match.yaml海尔数据源文件

这是命名为proxy_match.yaml在herarchy /etc/puppetlabs/code/environments/proxy_match/data/proxy-match.yaml的YAML hiera源

---
profiles::apache::servername: "taraserver.com"
profiles::apache::port: "80"
profiles::apache::docroot: "/var/www/tarahost"

在外形hiera查找

$servername  = hiera('profiles::apache::servername',{})
  $port        = hiera('profiles::apache::port',{})
  $docroot     = hiera('profiles::apache::docroot',{})
  class profile::apache{
    #configure apache
    include apache
    apache::vhost{$servername:
      port    => $port,
      docroot => $docroot,
    }
  }

＃错误：

Answer 1

您所定义的类定义之外的变量。当木偶加载一个类，类之前你有这些行会被忽略。

你应该在你的个人资料类：

class profiles::apache (
  String $servername,
  Integer $port,
  String $docroot,
) {
  include apache
  apache::vhost { $servername:
    port    => $port,
    docroot => $docroot,
  }
}

请注意，我用的automatic parameter lookup功能，将您的变量，而不是显式调用到hiera功能。
