salt 根据ip修改主机名

Posted 2021-01-09 lfdblog

首先定义pillar

[[email protected] pillar]# cat hostname.sls 
ip_hostname:
  10.1.1.1: web1
  10.1.1.2: web2
  10.1.1.3: mysql1
  10.1.1.4: redis1
  10.1.1.5: tomcat1
  10.1.1.6: dubbo1
  10.1.1.7: zabbix1

在top.sls中调用

[[email protected] pillar]# cat top.sls 
base:
  ‘*‘:
    - hostname

编写状态模块，根据ip通过pillar判断对应的主机名。

[[email protected] base]# cat set-hostname.sls 
{% set ip = salt[‘network.interface_ip‘](‘eth1‘) %}
alter_hostname:
  cmd.run:
    - name: hostnamectl  set-hostname {{ pillar[‘ip_hostname‘][ip] }}

测试执行

[[email protected] base]# salt-ssh  ‘*‘ state.sls set-hostname  test=True
