运行Puppet 3.8
我有两个定义:
define desktop::vinstall () {
package { $title:
ensure => installed,
allow_virtual => true,
configfiles => keep,
}
}
和
define desktop::vinstallwseeds () {
package { $title:
ensure => installed,
allow_virtual => true,
configfiles => keep,
require => File["/var/cache/debconf/pkg-${title}.seeds"],
responsefile => "/var/cache/debconf/pkg-${title}.seeds",
}
file { "/var/cache/debconf/pkg-${title}.seeds":
source => "puppet:///modules/desktop/pkg-${title}.seeds",
ensure => present,
}
}
想将这些转换为带有可选布尔参数的一个define语句,如:
define desktop::vinstallopt ( $queryresponse = 'false', ) {
package { $title:
ensure => installed,
allow_virtual => true,
configfiles => keep,
if $queryresponse == 'true' {
require => File["/var/cache/debconf/pkg-${title}.seeds"],
responsefile => "/var/cache/debconf/pkg-${title}.seeds",
}
}
file { "/var/cache/debconf/pkg-${title}.seeds":
source => "puppet:///modules/desktop/pkg-${title}.seeds",
ensure => present,
}
}
然后使用init.pp中的语句实例化它:
@desktop::vinstallopt { 'gdebi': queryresponse => 'false', }
但这样做会出错:
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Puppet::Parser::AST::Resource failed with argument error ArgumentError: Invalid resource type desktop::vinstallopt at /etc/puppet/modules/desktop/manifests/init.pp:40 on node machine.prvt.net
其中第40行具有上述语法。我是一个有木偶的新手,所以我很抱歉这是一个简单的语法问题。我试图从PuppetLabs文档和其他木偶用户那里找到一种方法来完成这项工作,到目前为止还没有运气。

您正尝试在资源声明中嵌入if
块。唉,这是不可能的。该块必须是全局的或在常规块中(例如,类主体,定义主体,lambda主体)。
在这种情况下,您希望"修改"可以这么说package
资源。我喜欢为此目的使用以下构造:
package { $title:
ensure => installed,
allow_virtual => true,
configfiles => keep,
}
if $queryresponse {
Package[$title] {
require => File["/var/cache/debconf/pkg-${title}.seeds"],
responsefile => "/var/cache/debconf/pkg-${title}.seeds",
}
}
请注意,此范围内仅允许此覆盖语法,因为require
和responsefile
属性最初没有分配任何值。
