Saltstack--pillar

5. Pillar
pillar and grains are not the same, they are defined on the master and are some information that is defined for minion. Like some of the more important data (passwords) can exist in pillar, you can also define variables and so on.

View the pillar value for the specified minion (the version I tested is empty):
Salt ' client.aming.com ' Pillar.items

Configure the Custom pillar

Vim/etc/salt/master//operation on Master

Locate the following configuration:
pillar_roots:
Base:
-/srv/pillar
remove the front siren.
Mkdir/srv/pillar
Vi/srv/pillar/test.sls//content is as follows
conf:/etc/123.conf

Vi/srv/pillar/top.sls//content is as follows
Base:
' client.aming.com ':
-Test

Module name cannot be a number

Restart Master
/etc/init.d/salt-master Restart

after the pillar configuration file is changed, we can get the new pillar state by refreshing the pillar configuration:
Salt ' * ' saltutil.refresh_pillar

Verify:

Salt ' * ' Pillar.item test

Pillar can also be used as a matching object for salt. Like what

Salt-i ' conf:/etc/123.conf ' test.ping
