标签能更好的让puppet识别一段代码。同时,客户端也可以执行指定的tag,而不需要全部都执行。
tag元参数,用于标签资源;
tag函数,用于标签容器;
tagged函数,用于判断一个容器,是否有某个标签,即用于检查tag函数。
puppet的自动分配标签分两种:资源和容器。默认是以自己的类型,作为标签名。
资源自动分配标签的特点:
①自己的资源类型;
②title;
③所在容器的类型;
④所在容器的tital和每个命名空间;
⑤继承的tag。
容器自动分配标签的特点:
①自己的类型;
②title和每个命名空间;
注:凡title的内容有“/”,该title不会被添加为标签名。
#title含/ file {"/tmp/filebucket": ensure => file, content => "hello wrold", } |
#title不含/ file {"filebucket": path => "/tmp/filebucke ", |
①.tag元参数:
一般用于,各种资源,可以使用数组。
格式:
tag => "标签名", tag => ["标签名1",…, "标签名n"], |
注:可放入到任何一类资源。
例:
# cron { "run-puppet": command => "/usr/sbin/puppet agent --server=master.perofu.com --test >/dev/null 2>&1", minute => inline_template("<%= (hostname+name).hash.abs % 60 %>"), tag => "cron_test", [root@master manifests]# crontab -l # HEADER: This file was autogenerated at Fri Mar 21 15:24:59 +0800 2014 by puppet. # HEADER: While it can still be managed manually, it is definitely not recommended. # HEADER: Note particularly that the comments starting with 'Puppet Name' should # HEADER: not be deleted, as doing so could cause duplicate cron jobs. [root@master ~]# puppet agent --server=master.perofu.com --test --tags cron_test info: Caching catalog for master.perofu.com info: Applying configuration version '1395386333' notice: /Stage[main]//Cron[run-puppet]/ensure: created notice: Finished catalog run in 0.04 seconds # HEADER: This file was autogenerated at Fri Mar 21 15:43:55 +0800 2014 by puppet. # Puppet Name: run-puppet 32 * * * * /usr/sbin/puppet agent --server=master.perofu.com --test >/dev/null 2>&1 |
②.tag函数:
tag函数可以为容器添加标签,类名,默认就是标签名,个人理解:容器差不多是类,因为类用的多。
如果用户想添加另外的tag,需要在class的第一行,进行定义。
class 类名{ tag("标签名") ……. |
#容器的标签名现在有两个:ssh和security class ssh{ tag("security") service{"sshd": ensure => running, enable => true, } |
③.tagged函数:
判断一个容器的标签,即tag函数,是否被定义过。
vi site.pp if tagged("sss"){ $a="The tag is sss" } else { $a="The tag is NONE" file {"/tmp/temp.txt" content => "$a", cat /tmp/temp.txt The tag is NONE |
