SaltStack(四)Grains&Pillar

Grains

minion的静态属性信息，分为core grains和custom grains

core grains

查看grains列表

➜  ~ sudo salt 'AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6' grains.items
➜  ~ sudo salt 'AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6' grains.ls   

获取某个属性

➜  ~ sudo salt 'AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6' grains.item zmqversion
AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6:
    ----------
    zmqversion:
        4.1.4

➜  ~ sudo salt 'AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6' grains.get zmqversion
AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6:
    4.1.4

custom grains

自定义grains有多个地方可以定义:

1. Core grains.
2. Custom grains in /etc/salt/grains.
3. Custom grains in /etc/salt/minion.
4. Custom grain modules in _grains directory, synced to minions.

/etc/salt/minion配置文件当中

# Custom static grains for this minion can be specified here and used in SLS
# files just like all other grains. This example sets 4 custom grains, with
# the 'roles' grain having two values that can be matched against.
grains:
  roles:
    - webserver
    - memcache
  deployment: datacenter4
  cabinet: 13
  cab_u: 14-15

配置完成后，需要刷新一下

➜  ~ sudo salt 'AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6' saltutil.sync_grains
AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6:
➜  ~ sudo salt 'AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6' grains.get roles       
AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6:
    - webserver
    - memcache

Tips: 若配置错误，minion会挂掉

/etc/salt/grains配置，简单配置了一个app信息

app:
  loc: hangzhou
  name: ZHJY

➜  ~ sudo salt 'AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6' saltutil.sync_grains
AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6:
➜  ~ sudo salt 'AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6' grains.get app      
AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6:
    ----------
    loc:
        hangzhou
    name:
        ZHJY

Pillar

存放在master端的数据结构信息，由/srv/pillar/top.sls文件进行统管控制

base:
  '*':
    - log

添加了一个log的配置在/etc/pillar/log.sls

# /srv/pillar/log.sls
# 日志配置
Logger:
  # 日志存放路径，当前目录的log文件夹
  Path: "/tmp/cloudboot/logs"
  # 日志打印等级，[debug, info, warn, err, off]
  Level: "debug"
  # 最大存放时间，7天，超过7天的日志会删除
  MaxAge: 7
  # 日志分割时间，24小时，日志以1天为单位分割，一天一个文件
  RotationTime: 24

查看pillar列表

➜  pillar sudo salt 'AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6' pillar.items
AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6:
    ----------
    Logger:
        ----------
        Level:
            debug
        MaxAge:
            7
        Path:
            /tmp/cloudboot/logs
        RotationTime:
            24

刷新pillar

➜  salt sudo salt '*' saltutil.refresh_pillar

使用jinjia动态参数配置

通用

输出为json的时候数据结果不会进行合并，添加static参数

➜  ~ sudo salt '*' grains.get fqdn_ip4 --out=json         
{
    "AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6": [
        "172.18.0.2"
    ]
}
{
    "E84B4F5F-0000-0000-BBD1-FA294FBCB7D5": [
        "172.18.0.3"
    ]
}
➜  ~ sudo salt '*' grains.get fqdn_ip4 --out=json --static
{
    "AAAAAAAA-0000-0000-BBD1-FA294FBCB7D6": [
        "172.18.0.2"
    ], 
    "E84B4F5F-0000-0000-BBD1-FA294FBCB7D5": [
        "172.18.0.3"
    ]
}
