在augeas中修改yml文件

标签: puppet puppet-enterprise augeas

我正在尝试通过/etc/elasticsearch/elasticsearch.yml资源修改/设置puppet清单中的augeas文件,但它无效。有人可以解释我应该指定的lens文件吗?我是否需要为此安装额外的东西或默认安装中包含所需的镜头?

我正在尝试更改键值对:

 key1.key2:  value
 eg:


cluster.name: cms-es

我的代码:

  augeas { "elastic_config":
  context => "/files/etc/elasticsearch/elasticsearch.yml",
  changes => [
  "set 'network.host:' ipaddress_eth0",
  "set 'cluster.name:' cms-es",
  "set 'node.name:' ec2_hostname",
  "set 'bootstrap.mlockall:' true",
 ],
}

Augeas目前无法编辑YAML文件,因为无法使用Augeas镜头描述YAML语法。它需要修改Augeas的核心来支持它(以支持一致的标识,这对于这种格式是强制性的。)

不是最好的解决方案,但如果你只依赖冒号分隔的配置文件,我只是为了这个镜头。

复制&将以下内容粘贴到/usr/share/augeas/lens/colonvars.aug中(或使用auges模块自动执行此操作)。

(start code)
    augtool> set /augeas/load/Colonvars/lens "Colonvars.lns"
    augtool> set /augeas/load/Colonvars/incl "/etc/elasticsearch/elasticsearch.yml"
    augtool> load

    augtool> get /files/etc/elasticsearch/elasticsearch.yml/cluster.name
    /files/etc/elasticsearch/elasticsearch.yml/cluster.name = elk

    augtool> set /files/etc/elasticsearch/elasticsearch.yml/node.name elk-node-0
    augtool> save
    Saved 1 file(s)

    $ grep node.name /etc/elasticsearch/elasticsearch.yml
    node.name: elk-node-0

module Colonvars =

   let colon = del /[ \t]*:[ \t]*/ ": "
   let entry = Build.key_value_line Rx.word colon (store Rx.space_in)
   let lns   = (Util.empty | Util.comment | entry)*

以下是如何使用它(基于您的示例):

augeas { "elastic_config":
    incl => "/etc/elasticsearch/elasticsearch.yml",
    lens => "Colonvars.lns",
    changes => [
        "set network.host ipaddress_eth0",
        "set cluster.name cms-es",
        "set node.name ec2_hostname",
        "set bootstrap.mlockall true",
    ]
}
