人偶 3.8.x 变量无法应用于模板

Question

module/bareos_backup_client/manifests/init.pp:

class bareos_backup_client {
      @@file { "${fqdn}-bareos-client.conf":
            mode => 600,
            owner => bareos,
            group => bareos,
            path => "/etc/bareos/director.d/${fqdn}-client.conf",
            content => template("bareos_backup_client/bareos-dir-cliententry.erb"),
            tag => 'bareos-client',
            notify => Service[bareos-dir],

    }        
}

module/bareos_backup_client/templates/bareos-dir-cliententry.erb:

  <% if @clientrunbeforejob -%>
  ClientRunBeforeJob  = "<%=  @clientrunbeforejob %>"
  <% end -%>
  <% if @clientrunafterjob -%>
  ClientRunAfterJob = "<%=  @clientrunafterjob %>"
  <% end -%>

manifests/nodes/server_1.pp:

  include bareos_backup_client
  $clientrunbeforejob = "apple"

为什么clientrunbeforejob变量不能注入erb模板？

Answer 1

您尝试使用 dynamic scoping。这多年来一直没有奏效，这是有充分理由的！

您可能希望将此值作为 class parameter.

传递

class bareos_backup_client($clientrunbeforejob) {
  ...
}

然后像这样声明它

class { 'bareos_backup_client':
  clientrunbeforejob => 'apple'
}
