saltstack模式匹配

salt匹配规则有多种，对应各种不同的场景，相关参数如下图所示。现总结如下：

1、正则匹配

[root@salt-master~]#salt-E'salt-minion(01|02).contoso.com'test.ping
salt-minion01.contoso.com:
True
salt-minion02.contoso.com:
True
[root@salt-master~]#salt-E'salt-minion0[1-2].contoso.com'test.ping
salt-minion02.contoso.com:
True
salt-minion01.contoso.com:
True

2、列表匹配

[root@salt-master~]#salt-L'salt-minion01.contoso.com,salt-minion02.contoso.com'test.ping
salt-minion01.contoso.com:
True
salt-minion02.contoso.com:
True

3、Grains匹配

saltstack Grains项可以通过如下命令获取：

root@salt-master~]#salt'salt-minion01.contoso.com'grains.items
salt-minion01.contoso.com:

当然，也可以就某一个Grains项进行查询，如下所示：

[root@salt-master~]#salt'salt-minion01.contoso.com'grains.itemos
salt-minion01.contoso.com:
----------
os:
CentOS
[root@salt-master~]#salt'salt-minion01.contoso.com'grains.itemkernelrelease
salt-minion01.contoso.com:
----------
kernelrelease:
2.6.32-431.el6.x86_64
[root@salt-master~]#salt'salt-minion01.contoso.com'grains.itemhost
salt-minion01.contoso.com:
----------
host:
salt-minion01

获取到上述Grains项之后，就可以有目的的进行匹配了，示例如下：

[root@salt-master~]#salt-G'os:CentOS'test.ping
salt-minion02.contoso.com:
True
salt-minion01.contoso.com:
True
[root@salt-master~]#salt-G'kernelrelease:2.6.32-431.el6.x86_64'test.ping
salt-minion02.contoso.com:
True
salt-minion01.contoso.com:
True

4、组匹配

首先，编辑master的配置文件，并添加如下内容：

vim /etc/salt/master

nodegroups:

testgroup1: 'L@salt-minion01.contoso.com,salt-minion02.contoso.com'

testgroup2: 'G@os:CentOS and G@domain:contoso.com'

testgroup3: 'G@os:CentOS and E@salt-minion01.*'

然后就可以根据master配置中定义中的组进行匹配，示例如下：

[root@salt-master~]#salt-Ntestgroup1test.ping
salt-minion01.contoso.com:
True
salt-minion02.contoso.com:
True
[root@salt-master~]#salt-Ntestgroup2test.ping
salt-minion01.contoso.com:
True
salt-minion02.contoso.com:
True
[root@salt-master~]#salt-Ntestgroup3test.ping
salt-minion01.contoso.com:
True

5、复合匹配

[root@salt-master~]#salt-C'G@os:CentOSandE@salt-minion02*'test.ping
salt-minion02.contoso.com:
True
salt-minion01.contoso.com:
True
[root@salt-master~]#salt-C'G@host:salt-minion01orL@salt-minion02.contoso.com'test.pingsalt-minion01.contoso.com:
True
salt-minion02.contoso.com:
True
[root@salt-master~]#salt-C'G@host:salt-minion01andG@domain:contoso.com'test.ping
salt-minion01.contoso.com:
True

6、CIDR匹配

[root@salt-master~]#salt-S'192.168.49.0/24'test.ping
salt-minion01.contoso.com:
True
salt-minion02.contoso.com:
True
[root@salt-master~]#salt-S'192.168.49.101'test.ping
salt-minion01.contoso.com:
True

7、Pillar匹配（暂时省却，后续添加）
