问题描述
假设我有:
$files = ["file1", "file2"]
exec { "exec1" :
command => "mycommand";
}
file { $files :
ensure => present;
}
我想使用 ->
和 ~>
结构来控制通知/要求执行顺序,如下所示:
And I want to use the ->
and ~>
constructs to control the notify/require order of execution, like so:
Exec["exec1"] -> File[$files]
我该怎么做?
如果我执行上述操作,我会得到 Could not find resource 'File[file1]File[file2]'
(当然,对于真实文件路径).我尝试将 $files
变量包装在引号和 {} 中,但无济于事.
If I do the above, I get Could not find resource 'File[file1]File[file2]'
(for real file paths, of course). I've played with wrapping the $files
variable in quotes and {}s, but to no avail.
将资源名称的数组变量放入排序链的语法是什么?
What's the syntax for putting an array variable of resource names into an ordering chain?
推荐答案
您可以使用 来自 RIPienaar 的这个很棒的提示列表:
首先定义一个处理链接的函数,然后将您的数组传递给该函数.
该函数将为数组中的每个项目调用一次.
First define a function that handles the chaining, then pass in your array to the function.
The function will get called once for each item in the array.
代码采样时间:
exec { "exec1":
command => "/bin/echo 'i am the very model of a modern major general'";
}
file {
"/var/tmp/file1":
ensure => present;
"/var/tmp/file2":
ensure => present;
}
define chaintest() {
notify{"Calling chaintest with ${name}": }
Exec["exec1"] -> File["${name}"]
}
$files = ["/var/tmp/file1","/var/tmp/file2"]
chaintest{$files: }
'puppet apply test.pp' 在 Ubuntu 12.04 上的 puppet 2.7.11 上的输出给出:
The output of 'puppet apply test.pp' on puppet 2.7.11 on Ubuntu 12.04 gives:
notice: Calling chaintest with /var/tmp/file1
notice: /Stage[main]//Chaintest[/var/tmp/file1]/Notify[Calling chaintest with /var/tmp/file1]/message: defined 'message' as 'Calling chaintest with /var/tmp/file1'
notice: /Stage[main]//Exec[exec1]/returns: executed successfully
