如何检查人偶中是否存在目录 [英] How to check if a directory exists in puppet

问题描述

尝试使用 puppet 在 rpi 上创建自动启动目录.仅当该位置不存在时才应该 mkdir.

Trying to create an autostart directory on a rpi using puppet. It is supposed to mkdir only if the location doesn't exist.

这是当前代码:

exec { "mkdir_autostart":
command => "mkdir /home/pi/.config/autostart",
unless => "[ -d /home/pi/.config/autostart ]",
path    => "/usr/local/bin/:/bin/",
}

这是我得到的:

err: Failed to apply catalog: Parameter unless failed on Exec[mkdir_autostart]: 
'[ -d  /home/pi/.config/autostart ]' is not qualified and no path was specified.
Please qualify the command or specify a path.

也尝试过使用 onlyif 语句，但产生了同样的错误.我做错了什么?

Also tried with onlyif statement, but that generated the same error. What am I doing wrong?

添加路径(path => "/usr/local/bin/:/bin/", )，现在得到:

Added path (path => "/usr/local/bin/:/bin/",) and now get:

err: /Stage[main]/auto::Sign/Exec[mkdir_autostart]: Could not evaluate: Could not find command '['

推荐答案

您应该使用文件"类型:

You should use the "file" type:

file { "/home/pi/.config/autostart":
   ensure => directory
}

但如果出于任何原因，您想保留exec"类型，请使用 test -d/home/pi/.config/autostart

But if for any reason, you want to keep your "exec" type, use test -d /home/pi/.config/autostart
