首先定义pillar
[root@web1 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
[root@web1 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。
[root@web1 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
[root@web1 base]# salt-ssh '*' state.sls set-hostname test=True
