with_items标准循环

1.为不同用户定义不同组

---
- hosts: web2
  remote_user: root
  tasks:
    - user:
        name: "{{item.name}}"
        group: "{{item.group}}"
        password: "{{'123456'|password_hash('sha512')}}"
      with_items:
        - {name: "aa", group: "users"}
        - {name: "bb", group: "mail" }
        - {name: "cc", group: "wheel"}
        - {name: "dd", group: "root" }

运行

#  ansible-playbook add.yml

注意item.name 中间是点，组是自己存在的

 2.嵌套循环，循环添加多用户

---
- hosts: web2
  remote_user: root
  vars:
    un: [a, b, c]
    id: [1, 2, 3]
  tasks:
    - name: add users
      shell: echo {{item}}
      with_nested:
        - "{{un}}"
        - "{{id}}"
