Compound matchers

Compound matcher

A combination of many target definitions that can be combined with boolean operators.

Compound matchers allow very granular minion targeting using any of the previously discussed matchers. The default matcher is a glob, as usual. For matching via anything other than glob, preface it with the letter denoting the match type. The currently implemented "letters" are:

Letter	Meaning	Example
G	Grains glob match	G@os:Ubuntu
E	PCRE Minion id match	E@web\d+\.(dev|qa|prod)\.loc
P	Grains PCRE match	P@os:(RedHat|Fedora|CentOS)
L	List of minions	L@minion1.example.com,minion3.domain.com or bl*.domain.com
I	Pillar glob match	I@pdata:foobar
S	Subnet/IP addr match	S@192.168.1.0/24 or S@192.168.1.100
R	Range cluster match	R@%foo.bar

Matchers can be joined using boolean and, or, and not operators.

For example, the following command matches all minions that have a hostname that begins with "webserv" and that are running Debian or it matches any minions that have a hostname that matches the regular expression web-dc1-srv.*:

salt -C 'webserv* and G@os:Debian or E@web-dc1-srv.*' test.ping

That same example expressed in a top file looks like the following:

base:
  'webserv* and G@os:Debian or E@web-dc1-srv.*':
    - match: compound
    - webserver
