如何解决 Chef 类型错误：使用 node.normal "no implicit conversion of String into Integer"？

Question

我目前正在测试一本新的厨师食谱，用于zabbix监视，并使用本食谱使我的第一个成功的'厨师'。但是，我被迫更改其中一个属性，因为它将从服务器更改为服务器。我决定使用数据袋，并且很难检索和分配属性。

这是数据袋的内容：

    [user@workstation chef-repo]# knife data bag show zabbix_psk psk_syslog
    WARNING: Unencrypted data bag detected, ignoring any provided secret options.
    id:  psk_syslog
    psk: PSK 060

我没有在属性文件中分配属性，而是在食谱中分配： default.rb

keyvalue = data_bag('zabbix_psk')
node.normal['zabbix_agentd']['psk_number'] = keyvalue['psk_syslog']['psk']

然后我将其分配在模板中：

TLSPSKIdentity=<%= node['zabbix_agentd']['psk_number'] %>

当我尝试厨师时，我会收到以下错误并转储：

TypeError

我很难理解default.rb中的node.sormal分配有什么问题。我是厨师和Ruby的新手，所以我非常感谢您的帮助。我还应该注意，我无法使用方法 get_databag_item ;这种方法显然不存在？

data_bag('zabbix_psk')返回包中项目名称的数组，而不是所有项目中的数据。您需要data_bag_item('zabbix_psk', 'psk_syslog')，然后调整您对返回的值的使用。
