saltstack grains

Posted 2020-10-20 FRESHMANS

saltstack的grains类似于ansible的setup模块，主要作用为手机客户端的主机基本信息（cpu，内核，os，virtual等）

 

[[email protected]_master ~]# cat /etc/salt/master |grep -v "^#\|^$"
cachedir: /var/cache/salt/master
auto_accept: True
file_recv: True
file_roots:
  base:
    - /root
nodegroups:
   master1: ‘[email protected]_master‘
   agents: ‘[email protected]_node1,k8s_node2‘

查看主机的详细信息

salt -N ‘master1‘ grains.items

 

 

查看所有键

[[email protected]_master ~]# salt -N master1 grains.ls

[[email protected]_master ~]# salt -N master1 grains.item ipv4
k8s_master:
    ----------
    ipv4:
        - 10.1.14.0
        - 127.0.0.1
        - 172.17.0.1
