Arrays 木偶阵

我想知道如何解决以下puppet问题：我想基于字符串数组创建几个文件。复杂的是，我想用以下文件创建多个目录：

dir1/
    fileA
    fileB
dir2/
    fileA
    fileB
    fileC

问题是文件资源标题必须是唯一的。因此，如果我将文件名保留在一个数组中，我需要以自定义方式迭代该数组，以便能够用目录名对文件名进行后缀：

$file_names = ['fileA', 'fileB']
$file_names_2 = [$file_names, 'fileC']

file {'dir1': ensure => directory }
file {'dir2': ensure => directory }

file { $file_names: path = 'dir1', ensure =>present, }
file { $file_names_2: path = 'dir2', ensure =>present, }

这不起作用，因为文件资源标题冲突。因此，我需要在文件标题中添加目录名，但是，这将导致文件数组被连接起来，而不是被视为多个文件

啊

file { "${file_names}-dir1": path = 'dir1', ensure =>present, }
file { "${file_names_2}-dir2": path = 'dir1', ensure =>present, }

如何解决这个问题而不必重复文件资源本身。

谢谢，我试过了。您可以以此为例，根据您的具体需要进行修改

并创建目录和文件：

ls /var/tmp/dir*/
/var/tmp/dir1/:
fileA  fileB

/var/tmp/dir2/:
fileA  fileB  fileC
