标签：puppet tag
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；
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。
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": ensure => file, content => "hello wrold", path => "/tmp/filebucke ", }
|
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 [root@master manifests]# crontab -l # HEADER: This file was autogenerated at Fri Mar 21 15:43:55 +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. # Puppet Name: run-puppet 32 * * * * /usr/sbin/puppet agent --server=master.perofu.com --test >/dev/null 2>&1 |
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。
格式：
class 类名{ tag("标签名") ……. } |
例：
#容器的标签名现在有两个：ssh和security class ssh{ tag("security") service{"sshd": ensure => running, enable => true, } } |
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 |
