在Puppet中定义函数时收到错误。 C:\Windows\system32> puppet agent --test --server davidhromyk.test.5.puppet.lrscorp.net --masterport 8937 --ssldir C:\Temp\davidhromyk.test.5.puppet.lrscorp.net Info: Using configured environment 'internal' Info: Retrieving pluginfacts Info: Retrieving plugin Info: Retrieving locales Info: Loading facts Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Unknown function: 'driver_name'. (file: /home/david.hromyk/.puppetlabs/etc/code/environments/internal/modules/windows_print_server/manifests/init.pp, line: 12, column: 41) on node ops-dev-print01.lrscorp.net Warning: Not using cache on failed catalog Error: Could not retrieve catalog; skipping run
这是我的模块配置。
class windows_print_server (
$printers,
){
exec { 'Install-PrintServices':
command => 'Install-WindowsFeature -Name @("print-services","Print-LPD-Service")',
unless => '& { exit ((Get-WindowsFeature -Name Print-Services).installed -eq $false) }',
provider => powershell,
}
$printers.each |Integer $index, Hash $printer| {
exec { "add printer driver ${printer.driver_name} for ${printer.name}":
command => "Add-PrinterDriver -Name ${printer.driver_name}",
unless => "Get-PrinterDriver -Name ${printer.driver_name}",
}
exec { "add printer port $printer.port_name for ${printer.name}":
command => "Add-PrinterPort -Name ${printer.port_name}",
unless => "Get-PrinterPort -Name ${printer.port.name}",
}
exec { "add printer $$printer.name for $printer.name":
command => "Add-Printer -Name ${printer.name}",
unless => "Get-Printer -Name ${printer.name}",
}
}
}
这是我的希拉配置。

}
我相信在某个地方，我缺少$ {printer.driver_name}的init.pp语法。不确定执行此操作的正确方法。与$ {printer [“ name”]}相似吗？
从哈希访问值的语法[]在键周围使用方括号运算符：
$printer['driver_name']
在大多数情况下，键周围的引号是可选的，因为Puppet会将裸露的单词识别为字符串（这是Puppet语言的一般特征，并非特定于哈希键）。
要将值插值到字符串中，需要$用大括号将所有内容括起来：
$printers.each |Integer $index, Hash $printer| {
exec { "add printer driver ${printer[driver_name]} for ${printer[name]}":
command => "Add-PrinterDriver -Name ${printer[driver_name]}",
unless => "Get-PrinterDriver -Name ${printer[driver_name]}",
}
