如何在 Puppet 2.7 中将数组转换为逗号分隔的字符串

问题描述：

我使用的是 Puppet 2.7，我需要将数组转换为逗号分隔的列表.

I am using Puppet 2.7 and I need to convert an array to comma separated list.

$hosts_fqdn= ['host1','host2','host3']

我需要将其转换为所需的结果:'host1,host2,host3'

And I need to convert it to desired result: 'host1,host2,host3'

我猜 Puppet 3.2 提供了 lambda 表达式 - reduce.但不幸的是，这在 2.7 中是不可能的.

I guess that Puppet 3.2 offers lambda expression - reduce. But unfortunately that is not possible with 2.7.

答

Function join from puppetlabs/stdlib:

join($hosts_fqdn,",")
