Learning Puppet — Resources and the RAL

Official FAQ

自定义fact实现的四种方式介绍

** Resources: Imagine a system’s configuration as a collection of many independent atomic units; call them “resources.” * 资源可分类 * 资源类型描述抽离于它的具体操作步骤 * Puppet 指定资源的期望状态，而不是直接指定具体操作 * 以上三点组成 Puppet 的资源抽象层 （RAL）， RAL 包括 **types（高级别抽象模型） 和 providers（平台相关实现），这样可以使用平台无关的方式来描述资源得期望状态。

每个资源（Resource ）的描述包括： resource type, one** title, a number of **attributes, each attribute has a value

    user { 'dave':
      ensure     => present,
      uid        => '507',
      gid        => 'admin',
      shell      => '/bin/ksh',
      home       => '/home/dave',
      managehome => true,
    }
 

This syntax is called a resource declaration

Resource Types : puppet_core_types_cheatsheet.pdf, the type references

puppet describe : The puppet describe subcommand can list info about// the currently installed resource types// on a given machine.

puppet resource: Puppet includes a command called puppet resource, which can interactively inspect and modify resources on a single system. Usage:

# puppet resource <TYPE> [<NAME>] [ATTRIBUTE=VALUE ...]

.pp: Puppet programs are called “manifests,” and they use the .pp file extension.
