Api调用方式
piller组件定义与客户端相关的任何数据(定义在master端),定义好的数据可以被其他组件调用(如state,api)
说通俗了,一句话,就是ansible vars里定义的变量,可以在整个playbook中引用,只不过pillar中只有指定的minion自己能看到自己的数据。
启用piller功能并查看

【root@k8s_master ~】# systemctl restart salt-master

pillar 在sls中的使用
(1)定义pillar的主目录
【root@k8s_master ~】# cat /etc/salt/master |grep -v '^#|^$'
file_roots:
base:
- /rootpillar_opts: True #开启pillar功能
pillar_roots: #主目录
base:
- /srv/pillar
【root@k8s_master ~】# systemctl restart salt-master
#创建pillar目录
【root@k8s_master ~】# install -d /srv/pillar
其他参数
(1)pillar 源,salt支持引入pillar外部资源,例如从数据库导入pillar值,默认是关闭的
ext_pillar_first: False
(2)开启pillar gitgs ssl验证
pillar_gitfs_ssl_verify: True
(3)开启pillar render 错误信息
pillar_safe_render_error: True
(4)设置pillar配置合并策略
pillar_source_merging_strategy: smart
(2)定义入口文件top.sls及要引用的变量文件
即定义pillar的数据覆盖被控主机的范围(要执行的主机),''代表所有主机,及储存变量的文件(data.sls)
示例及测试:
【root@k8s_master pillar】# pwd
/srv/pillar
【root@k8s_master pillar】# ls
data.sls top.sls
【root@k8s_master pillar】# cat top.sls
base:
'':
- data
【root@k8s_master pillar】# cat data.sls
appname: master1
flow:
maxconn: 30000
maxmem: 1G
#测试
【root@k8s_master pillar】# salt 'k8s_master' pillar.data appname flow
k8s_master:
----------
appname:
master1
flow:
----------
maxconn:
30000
maxmem:
1G
如果显示不出结果,可用salt 'k8s_master' saltutil.refresh_pillar(saltutil.sync_all) 刷新pillar数据
【root@k8s_master pillar】# salt -I 'appname:master1' test.ping
k8s_master:
True
测试得出的结果可在state/模板等文件引用,引用方式如下:
格式:
{ { pillar变量 }}
#获取appname的值
{ { pillar【'appname'】 }} (一级字典)
#获取maxconn的值
{ { pillar【'flow'】【'maxconn'】 }} (二级字典)
{ { salt【'pillar.get'】('flow:maxconn',{})}}(二级字典)
pillar与jinja和grains的使用示例
【root@k8s_master pillar】# tree
.
├── data.sls
├── package.sls
├── top.sls
└── users
└── init.sls
1 directory, 4 files
【root@k8s_master pillar】# cat users/init.sls
hdfs:
namenode: 192.168.122.201
stadbynode: 192.168.122.202
hbase:
master: 192.168.122.201
【root@k8s_master pillar】# cat top.sls
base:
'':
- data
- package
- test.test ##此处表示根目录下test目录下的test.sls文件(即,/srv/pillar/test/test.sls)【详细见saltstack sls随笔】
- users #此处表示users目录,top.sls会知己恩引用users 目录下的 init.sls(所有)文件 【详细见saltstack sls随笔】
【root@k8s_master pillar】# cat data.sls
appname:
master1
flow:
maxconn: 30000
maxmem: 1G
【root@k8s_master pillar】# cat package.sls
pkgs: # 模块名称
{% if grains【'os'】 == 'CentOS' %} # 使用jinja模板,通过grains筛选主机
apache: httpd # 安装包名称
git: git
{% elif grains【'os'】 == 'SUSE' %}
apache: apache2
git: git-core
{% endif %}
查看结果:
【root@k8s_master pillar】# salt 'k8s_master' saltutil.refresh_pillar #刷新
k8s_master:
True
【root@k8s_master pillar】# salt 'k8s_master' pillar.items #获取数据
k8s_master:
----------
