ansible迭代子变量

需求

在某台机器上创建多个用户组，g1 g2 g3 创建用户user1 属于g1组，user2属于g2组，user3属于g3组。

需求实现

1. 编写yaml文件

---
- hosts: all
  remote_user: root

  tasks:
    - name: create group
      group: name={{ item }}
      loop:
        - g1
        - g2
        - g3
    - name: create users
      user: name={{ item.name }} group={{ item.group }}
      loop:
        - { name: "test1", group: "g1" }
        - { name: "test2", group: "g2" }
        - { name: "test3", group: "g3" }
...

2. ansible运行
