【基本介绍】
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是用来存储全局变量的，格式跟state类似
【配置】
文件：/etc/salt/master
配置pillar的路径
##### Pillar settings #####
##########################################
# Salt Pillars allow for the building of global data that can be made selectively
# available to different minions based on minion grain filtering. The Salt
# Pillar is laid out in the same fashion as the file server, with environments,
# a top file and sls files. However, pillar data does not need to be in the
# highstate format, and is generally just key/value pairs.
pillar_roots:
base:
- /srv/salt/pillar
#ext_pillar:
# - hiera: /etc/hiera.yaml
# - cmd_yaml: cat /etc/salt/yaml
# The pillar_gitfs_ssl_verify option specifies whether to ignore ssl certificate
# errors when contacting the pillar gitfs backend. You might want to set this to
# false if you're using a git backend that uses a self-signed certificate but
# keep in mind that setting this flag to anything other than the default of True
# is a security concern, you may want to try using the ssh transport.
#pillar_gitfs_ssl_verify: True
# The pillar_opts option adds the master configuration file data to a dict in
# the pillar called "master". This is used to set simple configurations in the
# master config file that can then be used on minions.
#pillar_opts: True
【原则】
pillar namespace
1.merge content from multiple pillar files,so long as conflicts are avoided(整合变量忽略冲突的)
【使用】
salt '*' pillar.items 还回所有的pillar
使用方法：{{ pillar['foo'] }}
{{ salt['pillar.get']('foo', 'qux') }}
在state里面使用pillar
[root@vpn pillar]# cat top.sls
base:
'*':
- packages
[root@vpn pillar]# cat packages.sls
hn: hostname
[root@vpn pillar]# cat /srv/salt/sls_config/test.sls
This is test:
cmd.run:
- name: {{ pillar['hn']}}
[root@vpn pillar]#
