Question

我对puppet很新。我配置了hiera文件，其路径为/etc/puppetlabs/puppet/hiera.yaml，因此

version: 5

hierarchy: []

backends:
  - yaml

yaml:
  - datadir: /etc/puppetlabs/puppet/some_dir

我收到此错误

 Warning: The function 'hiera' is deprecated in favor of using 'lookup'. See https://docs.puppet.com/puppet/5.3/reference/deprecated_language.html
       (file & line not available)
    Error: Evaluation Error: Error while evaluating a Function Call, Lookup of key 'user_dir' failed:  The Lookup Configuration at '/etc/puppetlabs/puppet/hiera.yaml' has wrong type, unrecognized key 'backends'
      The Lookup Configuration at '/etc/puppetlabs/puppet/hiera.yaml' has wrong type, unrecognized key 'yaml' at /etc/puppetlabs/code/environments/production/manifests/site.pp:30:17 on node puppet,some_cluster_DNS.internal

最初，我为密钥:backends: :yaml:提供了这种格式，但它似乎不是5版本的常规格式，因此我删除了{{1}签名

有人有想法吗？

首先，就该警告而言，如果您使用的是Hiera＆gt; = https://puppet.com/docs/puppet/4.10/hiera_use_function.html，则必须从Hiera lookup函数切换到Puppet hiera函数。 / p>

其次，就该错误而言，我会参考有关如何设置Hiera 5配置文件的文档：https://puppet.com/docs/puppet/4.10/hiera_config_yaml_5.html

使用正确的格式，您的配置文件将如下所示：

# /etc/puppetlabs/puppet/hiera.yaml
version: 5

defaults:
  - data_hash: yaml_data
  - datadir: /etc/puppetlabs/puppet/some_dir

hierarchy: []

在Hiera 5中不允许在最后一行（为datadir后端指定特定的yaml_data）尝试执行的操作。如果要为datadir指定datadir一个特定的后端，那么你需要为该后端指定层次结构的级别（或者只是后端的datadir;你可以用它来自定义几个矩阵的深度）并在那里指定hierarchy: - name: yaml data data_hash: yaml_data datadir: /etc/puppetlabs/puppet/some_dir paths: - "%{trusted.certname}.yaml" - common.yaml。例如：

package main

import (
    "fmt"
    "encoding/json"
)


type b struct {
    Name string  `json:"name"`
    Description string
    Url string
}

type a struct {
    *b
    MimeType string  `json:"mimeType"`
}

func main() {
    bc := b{"test", "testdecription", "testurl"}
    ac := a{nil, "jpg"}

    ac.b = &bc

    js, _ := json.Marshal(ac)

    fmt.Println(string(js) )
}

puppet hiera无法读取yaml文件
