Question

我正在尝试通过Puppet（与Hiera）创建一个文件和一个符号链接。我在Ubuntu 16.04上运行，我正在使用所有最新的模块。该文件被称为＆＃34; a＆＃34;并且链接被称为＆＃34; b＆＃34;。这些文件不直接相关。

我有一个节点的init.pp文件：

define hiera::files (
    $ensure,
    $content= "",
    $target="/./.",
    $mode = "",
    $owner = "root",
    $force = "false" ) {

  file { $title:
    ensure  => $ensure,
    owner   => $owner,
    force   => $force,
    content => $content,
    mode    => $mode,
    target  => $target,
  }
}

create_resources('hiera::files', hiera_hash('files', {}))

node "default" {
  hiera_include('classes')
}

还有一个包含相应数据的node.yaml文件：

files:
   /etc/a.txt:
   ensure: "present"
   mode: "2770"
   owner: "simon"
   content: "[d] \n type = sss \n resource = samba_1"

/etc/b:
   ensure: "link"
   target: "/usr/share/b"
   mode: "777"

我尝试了其他变体，但我总是收到错误消息，指出content，source，target不能指定多个变体。两者都有可能吗？不是为了同一个文件，而是为了我想要的单独文件吗？

hiera::files 默认值是这里的问题，因为即使您未在Hiera哈希中指定content和target，它们也是设置：

define hiera::files ( $ensure, $content= "", $target="/./.", $mode = "",   $owner = "root", $force = "false" ){

将$content和$target默认值更改为undef，因此如果您要使用它们，则必须指定它们。

define hiera::files ( $ensure, $content = undef, $target = undef, $mode = "",   $owner = "root", $force = "false" ){

如果您确实需要这些默认值，那么您需要一种方法来避免在包含内容的文件上设置target，并在content的文件/符号链接上设置target，例如< / p>

define hiera::files ( $ensure, $content = undef, $target = undef, $mode = "",   $owner = "root", $force = "false" ){
  # Provide a default empty content value when ensure => present, and no content is given
  $real_content = $ensure ? {
    "present" => $content ? {
      undef   => "",
      default => $content,
    },
    default   => undef,
  }

  # Provide a default /./. target value when ensure => link, and no target is given
  $real_target = $ensure ? {
    "link"  => $target ? {
      undef   => "/./.",
      default => $target,
    },
    default => undef,
  }

  file { $title:
    ensure => $ensure,
    owner => $owner,
    force => $force,
    content => $real_content,
    mode => $mode,
    target => $real_target,
  }
}

或者最好使用单独的定义来明确行为。
