【问题描述】：

我正在尝试从标准操作码 nagios 食谱生成 nagios hosts.cfg 文件。使用标准配方，我不断从以下几行中得到相同的错误：

    Chef::Mixin::Template::TemplateError (undefined method `[]' for nil:NilClass) on line #19:

     17:   if node['cloud'].nil? && !n['cloud'].nil?
     18:     ip = n['cloud']['public_ipv4'].include?('.') ? n['cloud']['public_ipv4'] : n['ipaddress']
     19:   elsif !node['cloud'].nil? && n['cloud']['provider'] != node['cloud']['provider']
     20:     ip = n['cloud']['public_ipv4'].include?('.') ? n['cloud']['public_ipv4'] : n['ipaddress']
     21:   else
     22:     ip = n['ipaddress']

完整的文件在这里：

原文件注释如下：

    <% # decide whether to use internal or external IP addresses for this node
    # if the nagios server is not in the cloud, always use public IP addresses for cloud nodes.
    # if the nagios server is in the cloud, use private IP addresses for any
    #   cloud servers in the same cloud, public IPs for servers in other clouds
    #   (where other is defined by node['cloud']['provider'])
    # if the cloud IP is nil then use the standard IP address attribute.  This is a work around
    #   for OHAI incorrectly identifying systems on Cisco hardware as being in Rackspace

【问题讨论】：

能否请您提供有关您的节点配置的相关信息？你有node['cloud'] 设置吗？你想达到什么目的？
我在寻找节点“云”，但它不是一个属性，但它看起来确实是我看过的其他 SO 的搜索选项。 /n 根据原始文档，这也在上下文中。（添加上面的大小）
请不要忘记将答案标记为正确！ :)

【解决方案1】：

我没有尝试解决此问题，而是采取了以下解决方法：

    define host {
    use server
    address <%= node['ipaddress'] %>
    host_name <%= node[node['nagios']['host_name_attribute']] %>
    hostgroups <%= node['nagios']['server_role'] %>,<%= node['os'] %>
    }

这有效，而不是使用云 ip 配置。
