在资源"template[/etc/awslogs//cwlogs.cfg]]上执行操作"创建"时出错

我正在尝试执行厨师运行，但一直收到标题中的错误。日志输出如下所示；

我试着查看类似问题的现有答案，但它们都发现了不同的问题，似乎无法反映我的情况。

有人有什么建议吗？

Answer 1

问题是has上的.each将返回|key, value|。您只是在抓取key，它是一个字符串。然后调用string['something']，它需要对字符串进行索引。

如果您将第29行改为：

<% node['cloudwatch-cookbook']['cwlogs']['logfiles'].values do |group| -%>

你应该很乐意去。
