2.4-saltstack Pillar

Pillar

Pillar and grains are not the same, they are defined on the server 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.wyp.com ' pillar.items

Configure custom pillar on server

Vim/etc/salt/mster

Locate the following configuration:

Pillar_roots:

Base: #空两个空格

-/srv/pillar #继续空两个空格, YAML format. Fixed notation

Remove the previous # number

Mkdir/srv/pillar

VI/SRV/PILLAR/TEST.SLS//content as follows, customize some pillar information, the module name cannot start with a number.

Conf:/etc/123.conf

VI/SRV/PILLAR/TOP.SLS//content is as follows, the total Portal configuration file, otherwise the above configuration does not take effect.

Base

' Client.wyp.com ': #客户端列表

-Test #加载test

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: no reboot required

Salt ' * ' saltutil.refresh_pillar

Verify:

Salt ' * ' Pillar.items

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
