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 ",
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",

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,
}
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
