当我定义(?)一个资源,例如为了确保dir结构,有没有可用的循环?
When I define(?) a resource e.g. to ensure dir structure, are there any loops available?
像:
for X in [app1,app2] do: file { '/opt/app/' + X: ensure => directory, owner => 'root', group => 'root', mode => '0644', }我有几十个目录,我真的厌倦了声明它在木偶..它将需要15 LOC的bash。
I have tens of directories and I am really tired with declaring it in puppet.. It would take 15 LOC of bash.
任何想法?
推荐答案在木偶语言中,没有任何循环。
In the puppet language, no there are no loops.
但是您可以使用数组而不是标题的简单字符串,并使用相同的参数声明多个资源:
But you can use an array instead of a simple string for the title and declare several resources at the same time with the same params:
$b = '/opt/app' file { [ "$b/app1", "$b/app2" ]: ensure => directory, owner => 'root', group => 'root', mode => 0644, }您还可以通过不同的参数声明同一类型的许多资源使用; 结束每个资源,这比重复文件和 { s和} s:
You can also declare many resources of the same type with different params by ending each resource with a ;, which is a bit more compact than repeating the file and the {s and }s:
file { [ "$b/app1", "$b/app2" ]: ensure => directory, owner => 'root', group => 'root', mode => 0755; [ "$b/app1/secret", "$b/app2/secret" ]: ensure => directory, owner => 'root', group => 'root', mode => 0700; }在具体的文件中,您可以设置源代码并使用递归:
In the specific case of files, you can set up a source and use recursion:
file { "/opt/app": source => "puppet:///appsmodule/appsdir", recurse => true; }(这将需要该木马的目录结构的源代码用作来源)
(that would require having a source of that directory structure for puppet to use as the source)
您可以定义新的资源类型多次重用参数的一部分:
You can define a new resource type to reuse a portion of the param multiple times:
define foo { file { "/tmp/app/${title}": ensure => directory, owner => 'root', mode => 0755; "/tmp/otherapp/${title}": ensure => link, target => "/tmp/app/${title}", require => File["/tmp/app/${title}"] } } foo { ["app1", "app2", "app3", "app4"]: }从Puppet 2.6开始,有一个可用的Ruby DSL,具有所有循环功能要求: www.puppetlabs/blog/ruby-dsl/
Starting with Puppet 2.6, there's a Ruby DSL available that has all the looping functionality you could ask for: www.puppetlabs/blog/ruby-dsl/ (I've never used it, however). In Puppet 3.2, they introduced some experimental loops, however those features may change or go away in later releases.
