salt pillar - storing global data in pillar

[size=large]saltstack 學習之pillar[/size]

【基本介紹】

Pillar is an interface for Salt designed to offer global values that can be distributed to all minions. Pillar data is managed in a similar way as the Salt State Tree.

pillar是用來存儲全局變量的，格式跟state類似

【配置】

檔案：/etc/salt/master

配置pillar的路徑

【原則】

pillar namespace

1.merge content from multiple pillar files,so long as conflicts are avoided(整合變量忽略沖突的)

【使用】

salt '*' pillar.items 還回所有的pillar

使用方法：{{ pillar['foo'] }}

{{ salt['pillar.get']('foo', 'qux') }}

在state裡面使用pillar

[code="linux"]

# cat top.sls

base:

'*':

- packages

# cat packages.sls

hn: hostname

# cat /srv/salt/sls_config/test.sls

This is test:

cmd.run:

- name: {{ pillar['hn']}}

#

[/code]
