create_resources - 不能轉換成字符串哈希

Question

我使用elasticsearch-logstash模塊從

https://forge.puppetlabs.com/elasticsearch/logstash

這是我hiera看起來像......

--- 
classes: 
    - 'profile::logstash' 


profile::logstash::conf: 
    package_url: "https://download.elasticsearch.org/logstash/logstash/packages/centos/logstash-contrib-1.4.2-1_efd53ef.noarch.rpm" 

，這是從配置文件logstash.pp

class profile::logstash { 

    $conf = hiera('profile::logstash::conf',{}) 


    validate_hash($conf) 


    create_resources('logstash',$conf) 

} 

我得到這個錯誤...

Error: can't convert String into Hash at /tmp/vagrant-puppet-2/modules-0/profile/manifests/logstash.pp:10 on node pw-idx-11.local 
Wrapped exception: 
can't convert String into Hash 
Error: can't convert String into Hash at /tmp/vagrant-puppet-2/modules-0/profile/manifests/logstash.pp:10 on node pw-idx-11.local 

UPDATE：

使用這個固定....

class profile::elasticsearch { 

    class { '::elasticsearch': 
    version => '1.1.1-1' 
    } 

    $elasticsearch_configs = hiera_hash('profile::elasticsearch::instance',{}) 

    validate_hash($elasticsearch_configs) 

    create_resources(elasticsearch::instance,$elasticsearch_configs) 

    package { 'java-1.7.0-openjdk.x86_64': 
    ensure => 'installed' 
    } 

} 

Answer 1

這就是做這件事的複雜的方式，怎麼樣

class profile::logstash($conf = {}) { 
    validate_hash($conf) 
    create_resources('logstash',$conf) 
} 

假設你的網站.pp你已經有

hiera_include('classes') 

參見在https://ask.puppetlabs.com/question/3608/parametrized-classes-with-hiera_includeclasses/

Answer 2

你的數據的示例不適合使用與create_resources，一個希望將嵌套散列。

data_identifier: 
    resource_title1: 
    res1_param1: value 
    res1_param2: value 
    resource_title2: 
    res2_param1: value 
    ... 

由於您的數據是平面散列，因此無法從中創建資源。您可能需要添加資源標題圖層。
