Puppet : How to use [class Section]2024/09/12

	It's possible to manage some resources by using [class] section like follows.
[1]	It's an example to define and use [sample01] class.

root@dlp:~ #

vi /usr/local/etc/puppet/code/environments/production/manifests/class.pp

class sample01 {
  file { '/home/testfile7.txt':
    ensure  => file,
    owner   => 'root',
    group   => 'wheel',
    mode    => '0644',
    content => 'This is the puppet test file.',
  }
  user { 'serverworld':
    ensure     => present,
    home       => '/home/serverworld',
    managehome => true,
    password   => '$6$v/Mo7qyDFJU9d*****',
    }
}
node 'node02.srv.world' { include 'sample01' }

[2]	It's an example to use inheritance of a class. The [sample01] and [sample02] class are both applied to [node02.srv.world] by this manifest.

root@dlp:~ #

vi /usr/local/etc/puppet/code/environments/production/manifests/class.pp

class sample01 {
  file { '/home/testfile7.txt':
    ensure  => file,
    owner   => 'root',
    group   => 'wheel',
    mode    => '0644',
    content => 'This is the puppet test file.',
  }
  user { 'serverworld':
    ensure     => present,
    home       => '/home/serverworld',
    managehome => true,
    password   => '$6$v/Mo7qyDFJU9d*****',
    }
}
class sample02 inherits sample01 {
  file { '/home/testfile8.txt':
    ensure  => file,
    owner   => 'root',
    group   => 'wheel',
    content => 'test file #8',
  }
}
node 'node02.srv.world' { include 'sample02' }
