1. View minion001 host use:

2.-e,--Pcre matches the host with regular expressions

Test if the host that has minion starts is connected

[Email protected] ~]# salt-e ' ^minion ' test.ping minion001:trueminion002:true[[email protected] ~]#

3.-l,--list, filtered in the form of a list of host IDs, similar in format to Python lists

Get System Information for minion001,minion002

[[email protected] ~]# salt -l  ' minion001, minion002 '  grains.items osfullnameminion002:    ----------     ssds:    biosreleasedate:        01/23/2012     biosversion:        6.00     cpu_flags:        - fpuminion001:    -- --------    SSDs:    biosreleasedate:         01/23/2012    biosversion:         6.00    cpu_flags:        - fpu         - vme        - de 

4.-g,--grain, matching filtering based on grains information of the host being controlled

The format is: ' <grain value>:<glob expression> '

Example: Filter the kernel for Linux host: Can be written, ' Kernel:linux '

[Email protected] ~]# salt-g ' osrelease:6.4 ' cmd.run ' python-v ' Minion001:python 2.6.6minion002:python 2.6.6[[em AIL protected] ~]#

If you need to mate with a regular expression, use the parameter--grain-pcre, tested only after the colon <glob expression> can use regular

[email protected] ~]# Salt--grain-pcre ' [a-z]+:linux ' test.ping No minions matched the target. No command was sent, no Jid was assigned. [[email protected] ~]# Salt--grain-pcre ' kernel:[a-z]+ ' test.ping minion001:trueminion002:true[[email p Rotected] ~]#

5.-i,--pillar matching filtering based on pillar information of the host being controlled

Format: "Object Name: Object Value"

Filter: ' APACHE:HTTPD ' "Nginx:root:/data"

Pending test ...

6.-n,--Nodegroup, filtering based on grouping in master configuration file/etc/salt/master on the host side

The definition of a group supports regular expressions, grain, conditional operations, etc.

7.-c,--compound, matching host information for different rules according to the conditional operator Not,and,or

Probe ID starts with minion, and the system is connected to the CentOS host

[Email protected] ~]# salt-c ' [email protected]^minion and [email protected]:centos ' test.ping Minion002:trueminio N001:true[[email protected] ~]#

8.-s,--IPCIDR match based on the IP address or IP subnet of the host being controlled

[Email protected] ~]# salt-s ' 192.168.224.142 ' test.pingminion001:true[[email protected] ~]# salt-s ' 192.168.224.0/ ' test.ping Minion002:trueminion001:true[[email protected] ~]#
