即使订阅的create_resource没有运行，puppet Exec也会一直运行

Question

我附上了工头的报告截图，下面粘贴的是我遇到问题的课程。

如果难以查看整个代码，我会突出显示Exec部分未按预期运行

exec { $service:
    path => ["/usr/bin/","/usr/sbin/","/bin"],
    subscribe  => Domain_ip_map[$domain_ip_map_titles],
    command => "sudo service nagios restart",   
}

上述Exec[$service]订阅Domain_ip_map[...]，Exec['purge-config-files']通知require => File['deployconfig.cfg']。

由于deployconfig.cfg文件没有变化，File['deployconfig.cfg']没有运行，因此没有通知，因此Exec['purge-config-files']和自定义Domain_ip_map资源不会跑。到目前为止，一切都按预期工作。但是最后一部分Exec[$service]订阅了Domain_ip_map。

  

Domain_ip_map未运行时，Exec[$service]如何执行   成功吗？

class testclass ( $data = {
        item1 => {
                domain      => 'testdomain.com',
                ipaddress   => '1.1.1.1',
        },
},
$baseconfigdir   = '/usr/local/servers',
$config_file_host = '/usr/local/test.cfg',
$config_file_service = '/usr/local/test_service.cfg' ) {

validate_hash($data)

$domain_ip_map_titles = keys($data)

file { "${baseconfigdir}": 
  ensure => directory,
}

exec { 'purge-config-files':
  command => "/bin/rm -f ${baseconfigdir}/*",
  notify => Domain_ip_map[$domain_ip_map_titles],
  require => File['deployconfig.cfg'],
  refreshonly => true,
}

file { 'deployconfig.cfg':
    ensure  => file,
    path    => '/home/deployconfig.cfg',
    mode    => '0644',
    owner   => 'root',
    group   => 'root',
    content => "test",    
    notify  => Exec['purge-config-files'],
} 

#problem here, its subscribed to Domain_ip_map, but even if Domain_ip_map doesn't run, Exec['$service'] always execute, how???
exec { $service:
    path => ["/usr/bin/","/usr/sbin/","/bin"],
    subscribe  => Domain_ip_map[$domain_ip_map_titles],
    command => "sudo service nagios restart",   
}

create_resources(domain_ip_map, $data)
}

define domain_ip_map($domain, $ipaddress)  {
nagios_host { $domain:
  ....
}

nagios_service { "check_ping_${domain}":
  ....
}   

}
