使用augeas with puppet将属性添加到根节点

Question

所以我正在尝试做一些看起来与" 通过augeas向XML根节点添加属性的问题"相同的问题,但是提供的答案对我不起作用.没有insert命令,我收到此错误消息(在puppet agent -t --debug --verbose模式下):

Debug: Augeas[context.xml](provider=augeas): /augeas/files/usr/share/tomcat/conf/context.xml/error/message = Failed to match

Debug: Augeas[context.xml](provider=augeas): Closed the augeas connection
Error: /Stage[main]/mytomcat::Hardening::Context-xml/Augeas[context.xml]: Could not evaluate: Saving failed, see debug

这基本上就是我们在其他帖子中看到的内容.使用insert命令,这是我正在使用的相关代码:

class mytomcat::hardening::context-xml {
  require ::augeas
  augeas{ 'context.xml':
    lens    => 'Xml.lns',
    incl    => '/usr/share/tomcat/conf/context.xml',
    changes => [
      'ins #attribute before Context/#text',
      'set Context/#attribute/allowLinking false', 
    ],
  }
}

这给了我这个错误:

Debug: Augeas[context.xml](provider=augeas): sending command 'ins' with params ["#attribute", "before", "/files/usr/share/tomcat/conf/context.xml/Context/#text"]
Debug: Augeas[context.xml](provider=augeas): Closed the augeas connection
Error: /Stage[main]/mytomcat::Hardening::Context-xml/Augeas[context.xml]: Could not evaluate: Error sending command 'ins' with params ["#attribute", "before", "/files/usr/share/tomcat/conf/context.xml/Context/#text"]/Error sending command 'ins' with params ["#attribute", "before", "/files/usr/share/tomcat/conf/context.xml/Context/#text"]

我尝试使用touch代替insert,基于Augeas 的" Puppet Type Reference "页面,使用以下代码:

class mytomcat::hardening::context-xml {
  require ::augeas
  augeas{ 'context.xml':
    lens    => 'Xml.lns',
    incl    => '/usr/share/tomcat/conf/context.xml',
    changes => [
      'touch Context/#attribute',
      'touch Context/#attribute/allowLinking',
      'set Context/#attribute/allowLinking false', 
    ],
  }
}

但后来我收到错误信息:

Error: /Stage[main]/mytomcat::Hardening::Context-xml/Augeas[context.xml]: Could not evaluate: Unknown command touch

编辑:我尝试做一个clear而不是触摸,但这似乎是一个NOOP命令,并没有给我一个不同于本文最顶部显示的第一个结果.

所以,我做不到touch,使用完整的XPath尝试设置属性不起作用,因为你必须在#text节点之前添加#attribute节点,clear看起来是一个NOOP,然后当我尝试做推荐的"插入"命令也不起作用.

知道这里出了什么问题以及如何解决它？
